COFRE DE PEROTE / NAUPA-TECVUTÉPTL SKETCHED BY ALEXANDER VON HUMBOLDT

 

ALEXANDER VON HUMBOLDT (1769-1859),
Cofre de Perote/ Naupa-Tecutépetl (4,282 m (14,049 ft)
Mexico

 The mountain
Cofre de Perote, also known by its Nahuatl names Naupa-Tecutépetl ,  meaning something like "Place of Four Mountain" or "Mountain of the Lord of Four Places", is an inactive volcano located in the Mexican state of Veracruz, at the point where the Trans-Mexican Volcanic Belt, home to all of Mexico's highest peaks, joins the Sierra Madre Oriental. Cofre de Perote is Mexico's eighth highest mountain summit.
Cofre de Perote is a shield volcano, shaped very differently from the stratovolcanic Pico de Orizaba, which lies about 50 km (31 mi) to the southeast. A cofre is a coffer, and the name alludes to a volcanic outcropping on the shield which constitutes the peak of the mountain. To the north is the town of Perote, Veracruz, after which the mountain is named. The area surrounding the volcano was protected by the Mexican government as a national park, known as Cofre de Perote National Park (Parque Nacional Cofre de Perote), in 1937.

The artist
Friedrich Wilhelm Heinrich Alexander von Humboldt was a Prussian geographer, naturalist, explorer, and influential proponent of Romantic philosophy and science. He was the younger brother of the Prussian minister, philosopher, and linguist Wilhelm von Humboldt (1767–1835). Humboldt's quantitative work on botanical geography laid the foundation for the field of biogeography. Humboldt's advocacy of long-term systematic geophysical measurement laid the foundation for modern geomagnetic and meteorological monitoring.
Between 1799 and 1804, Humboldt travelled extensively in Latin America, exploring and describing it for the first time from a modern scientific point of view. His description of the journey was written up and published in an enormous set of volumes over 21 years. Humboldt was one of the first people to propose that the lands bordering the Atlantic Ocean were once joined (South America and Africa in particular). Humboldt resurrected the use of the word cosmos from the ancient Greek and assigned it to his multi-volume treatise, Kosmos, in which he sought to unify diverse branches of scientific knowledge and culture. This important work also motivated a holistic perception of the universe as one interacting entity.
On their way back to Europe from Mexico on their way to the United States, Humboldt and his fellow scientist Aimé Bonpland stopped in Cuba for a while. After their first stay in Cuba of three months they returned the mainland at Cartagena de Indias (now in Colombia), a major center of trade in northern South America. Ascending the swollen stream of the Magdalena River to Honda and arrived in Bogotá on July 6, 1801 where they met Spanish botanist José Celestino Mutis, the head of the Royal Botanical Expedition to New Granada, staying there until September 8, 1801. Mutis was generous with his time and gave Humboldt access to the huge pictorial record he had compiled since 1783. Humboldt had hopes of connecting with the French sailing expedition of Baudin, now finally underway, so Bonpland and Humboldt hurried to Ecuador. They crossed the frozen ridges of the Cordillera Real, they reached Quito on 6 January 1802, after a tedious and difficult journey.
Their stay in Ecuador was marked by the ascent of Pichincha and their climb of Chimborazo, where Humboldt and his party reached an altitude of 19,286 feet (5,878 m). This was a world record at the time, but a thousand feet short of the summit. Humboldt's journey concluded with an expedition to the sources of the Amazon en route for Lima, Peru.
At Callao, the main port for Peru, Humboldt observed the transit of Mercury. On 9 November and studied the fertilizing properties of guano, rich in nitrogen, the subsequent introduction of which into Europe was due mainly to his writings.

MOUNT HAWKES / HAWKES HEIGHTS BY CHARLES HAMILTON SMITH

CHARLES HAMILTON SMITH (1776-1859),
Mount Hawkes / Hawkes Heights (2,000 m- 6,600 ft)
Antarctic (Coulman Island)

In Coulman Island, discovered Jan.4. 1844, watercolor on paper,

Yale Center for BRitish Art, New Haven, USA

The mountain
Mount Hawkes ( 2,000 m- 6,600 ft) also called  Hawkes Heights  is an ice-filled volcanic crater that dominates the southern part of Coulman Island, in the Ross Sea, Antarctica and marks the island's summit. The feature was named by the New Zealand Geological Survey Antarctic Expedition (NZGSAE), 1958–59, for Captain William M. Hawkes, U.S. Navy, who took a leading part in early air operations from Williams Field near McMurdo Station, including long range photo reconnaissance and supply flights, and the first air landing at the South Pole. He was commander of one of the two planes which made the historic first flight from Christchurch to McMurdo Station on December 17, 1955. His air photos proved of great value to two NZGSAE parties to this part of Victoria Land. Mount Hawkes is also named for Hawkes, who was assigned to Air Development Squadron Six (VX-6) in 1955–56.

The artist
Lieutenant-Colonel Charles Hamilton Smith, was an English artist, naturalist, antiquary, illustrator, soldier, and... spy as well !. His military career began in 1787, when he studied at the Austrian academy for artillery and engineers at Mechelen and Leuven in Belgium (his native country). Although his military service, which ended in 1820 and included the Napoleonic Wars, saw him travel extensively (including the West Indies, Canada, United States, Southern and Northern Europe and ...Antarctica).
As a prolific self-taught illustrator (over 38,000 drawings!) He left quite an important number of books of beautifully watercolored landscapes taken all around the world. those nooks of watercolors are nowadays in the collections of the Yale Center From British Art. Among them :
- Views of France, Volume I (81 watercolors), Views of France, Volume II (93 watercolors),
- Views of England and Wales, Volume I (82 watercolors), Views of England and Wales, Volume II (74 watercolors),
- Views of Northern Europe, Volume I (68watercolors) , Views of Northern Europe, Volume II (78) watercolors),
- Views of Polar Regions (75 watercolors) (see above)
- Views of Spain, Volume I (69 watercolors), Views of Spain, Volume II (72 watercolors), But one of his noteworthy achievements was an 1800 experiment to determine which color should be used for military uniforms. He is also known in military history circles for Costume of the Army of the British Empire, produced towards the end of the Napoleonic Wars and an accurate depiction of contemporary British uniform.
As an antiquarian, he also produced, in collaboration with Samuel Rush Meyrick, Costume of the Original Inhabitants of the British Islands, 1815, and The Ancient Costume of England, with historical illustrations of medieval knights, ladies, shipsm and battles.
He also wrote on the history of the Seven Years' War and The Natural history of dogs.
Quite a productive fellow !

MOUNT HADDINGTON BY CHARLES HAMILTON SMITH

Mount Haddington (1,630 m - 5,350 ft) 

Antarctica  (Ross Island) 

In Mount Haddington and Cape Gage from Views of Polar region, Watercolor and graphite, 
Yale Center for British Arts

The mountain 
Mount Haddington  (1,630 m - 5,350 ft) is a massive  high shield volcano comprising much of James Ross Island in Graham Land, Antarctica.  Mount Haddington was discovered on December 31, 1842 by the Ross expedition, a voyage of scientific exploration of the Antarctic from 1839 to 1843 led by James Clark Ross. Ross named the mountain after the Earl of Haddington, then First Lord of the Admiralty.
Mount Haddington is 60 km (37 mi) wide and has had numerous subglacial eruptions throughout its history, forming many tuyas. Some of its single eruptions were bigger in volume than a whole normal-sized volcano. Old eruption shorelines are widespread on the volcano's deeply eroded flanks.
Haddington formed along the Larsen Rift dominantly during the Miocene and Pliocene epochs but more recent eruptions have produced tuff cones on its slopes. The youngest tuff cones and pyroclastic cones on the eastern slope are situated below the summit icecap and may have formed in the last few thousand years. Effusive eruptions have created large deltas composed of hyaloclastite breccia and lava flows.

RANGITOTO VOLCANO BY JOHN BARR CLARK HOYTE

New Zealand (Rangitoto Island) 

 In Mount Ragitoto from St Georges' Bays Auckland, 1860, wash drawings,

 Alexander Turnbull Library 

The volcano

Rangitoto volcano   (260 m - 850 ft)  is a shield volcano  with a symetrical cone  situauted inthe center of  is a volcanic island in the Hauraki Gulf near Auckland, New Zealand. The 5.5 km wide island is an iconic and widely visible landmark of Auckland.  Rangitoto is the most recent and the largest (2311 hectares) of the approximately 50 volcanoes of the Auckland volcanic field.  It is separated from the mainland of Auckland's North Shore by the Rangitoto Channel. Since World War II, it has been linked by a causeway to the much older, non-volcanic Motutapu Island.

Rangitoto is Māori for  Bloody Sky, with the name coming from the full phrase Ngā Rangi-i-totongia-a Tama-te-kapua ("The days of the bleeding of Tama-te-kapua"). Tama-te-kapua was the captain of the Arawa waka (canoe) and was badly wounded on the island, after having lost a battle with the Tainui iwi (tribe) at Islington Bay.

The Painter 

John Barr Clark Hoyte was born in England, probably in London,  Nothing is known of Hoyte's education and artistic training and we are reduced to the obvious deduction that he was heir to the English tradition of topographic draughtsmanship and watercolour painting. Firm drawing underlies his landscapes, making it appropriate to group him with colonial surveyor–architect artists such as Edward Ashworth, Edmund Norman and George O'Brien.

During his years in New Zealand John Hoyte travelled assiduously in search of new scenes to exploit.   His pictorial exploration of the colony's principal dramatic landscapes was completed when he took a cruise circumnavigating the South Island in early 1877, exploring the coast of Fiordland with particular attention. New Zealand subjects would continue to inspire his production long after he had settled in Australia, where they shared his attention with coastal and mountain views drawn chiefly from the neighbourhood of Sydney.

Despite his apparent commercial success, however, Hoyte's standing, like that of George O'Brien, waned in the 1870s: a decade which marked a major shift in New Zealand colonial taste as the Turnerian Romantics such as Gully, J. C. Richmond and W. M. Hodgkins moved into greater prominence. They and their style were to dominate the following decades.

The artist

Charles Emilius Gold ) was a New Zealand soldier and artist. He was born in Woolwich, Kent, England on 6 January 1809. Gold purchased an ensign's commission in the 65th Regiment of Foot on 20 March 1828 and a lieutenant's commission on 28 October 1831; from 1830 until 1837 he was stationed in British Guiana and the West Indies; he served in Canada from 1838 till 1841. He rose, by purchase, to captain (1836) and major (1844) in the regiment, and was promoted to lieutenant colonel on 30 December 1845. While serving in Kingston, Canada, Gold married Eleanor Felicia Askin Geddes on 1 June 1839. They were to have 15 children.
In September 1846 the regiment was ordered to New Zealand and Gold and his family arrived at Auckland on 4 January 1847. He soon afterwards commanded a detachment of troops accompanying Governor George Grey to the Bay of Islands, in the aftermath of the northern war.
C. W. Richmond, who met him in 1857, described Gold as a 'pleasant gentlemanly soldierly fellow'. Garrison life during the years at Wellington was uneventful, but Eleanor Gold in particular cut a figure in the social life of the township, serving as hostess to her husband, and raising contributions for the Crimean patriotic fund.
During his periods of leisure Gold executed a number of idiosyncratic watercolour views, which show a rather childlike technique but in some cases a memorable, rhythmic vision of vegetation patterns. The paintings are largely of scenes around Wellington, Auckland and New Plymouth.

MAUNA KEA PAINTED BY CHARLES FURNEAUX

Mauna Kea   (4,207 m -13,802 ft) 

United States of America (Hawaii)

In  The village of Hilo and Mauna Kea,  oil on canvas, 1880s, Honolulu Art Museum

The mountain 
Mauna Kea (4,207 m -13,802 ft) is a dormant volcano on the island of Hawaii. Its peak is the highest point in the state of Hawaii making the island of Hawaii the second highest island in the world.
Most of the mountain is underwater : when measured from its oceanic base, Mauna Kea is over 10,000 m (33,000 ft) tall and is the tallest mountain on Earth.
Mauna Kea is about a million years old, and has thus passed the most active shield stage of life hundreds of thousands of years ago. In its current post-shield state, its lava is more viscous, resulting in a steeper profile. Late volcanism has also given it a much rougher appearance than its neighboring volcanoes; contributing factors include the construction of cinder cones, the decentralization of its rift zones, the glaciation on its peak, and the weathering effects of the prevailing trade winds.
 Mauna Kea last erupted 6,000 to 4,000 years ago and is now considered dormant.
In Hawaiian mythology, the peaks of the island of Hawaii are sacred. An ancient law allowed only high-ranking aliʻi to visit its peak. Ancient Hawaiians living on the slopes of Mauna Kea relied on its extensive forests for food, and quarried the dense volcano-glacial basalts on its flanks for tool production. When Europeans arrived in the late 18th century, settlers introduced cattle, sheep and game animals, many of which became feral and began to damage the mountain's ecological balance.
With its high elevation, dry environment, and stable airflow, Mauna Kea's summit is one of the best sites in the world for astronomical observation. Since the creation of an access road in 1964, thirteen telescopes funded by eleven countries have been constructed at the summit.
The Mauna Kea Observatories are used for scientific research across the electromagnetic spectrum and comprise the largest such facility in the world. Their construction on a landscape considered sacred by Native Hawaiians continues to be a topic of debate.

The painter 
Charles Furneaux was born in Boston and became a drawing instructor in that area. For many years he lived in the town of Melrose, Massachusetts. In 1880, Furneaux moved to Hawaii, where he cultivated the friendship of King Kalakaua and other members of the Hawaiian royal family, from whom he later received several commissions. In the late 1880s, he was commissioned in Honolulu by Alexander Joy Cartwright, widely credited as the "father of baseball" and another dear friend of King Kalakaua, to paint the only oil portrait of his 72-year life. While living in Honolulu he taught at the private schools Punahou and St. Albans (now known as Iolani School). In 1885, he received the order of Chevalier of Kapiolani from King Kalakaua in 'recognition of his services in advancing Hawaiian art'. He died in Hawaii in 1913.
His reputation is mainly based on the paintings he executed in Hawaii, especially those of erupting volcanoes. The Bishop Museum (Honolulu), the Brooklyn Museum, the Honolulu Museum of Art, Iolani Palace (Honolulu) and Mount Holyoke College Art Museum (South Hadley, Massachusetts) are among the public collections holding works by Charles Furneaux.

PAVONIS MONS BY NASA MARS GLOBAL SURVEYOR

 NASA MARS GLOBAL SURVEYOR  (1996-2007), 

Pavonis Mons (14,000m / 14km - 46,000ft / 8,7 mi) 

MARS

The mountain 

Pavonis Mons (14,000m / 14km - 46,000ft / 8,7 mi)  latin for "peacock mountain" is a large shield volcano located in the Tharsis region of the planet Mars. It is the middle member of a chain of three volcanic mountains (collectively known as the Tharsis Montes) that straddle the Martian equator between longitudes 235°E and 259°E. The volcano was discovered by the Mariner 9 spacecraft in 1971 and was originally called Middle Spot. Its name formally became Pavonis Mons in 1973.

Using NASA Mars Global Surveyor  and Odyssey data, combined with developments in the study of glaciers, scientists suggest that glaciers once existed on Pavonis Mons and probably still do to some extent.  Evidence for this includes concentric ridges (moraines "dropped" by glaciers), a knobby area (caused by ice sublimating), and a smooth section that flows over other deposits (debris-covered glacial ice). The ice could have been deposited when the tilt of Mars changed the climate, thereby causing more moisture to be present in the atmosphere. Studies suggest the glaciation happened in the Late Amazonian period, the most recent period in Mars chronology. Multiple stages of glaciation probably occurred. The ice present today represents one more resource for possible future colonization of the planet.

The mission
Mars Global Surveyor (MGS) was an American robotic spacecraft developed by NASA's Jet Propulsion Laboratory and launched November 7, 1996. Mars Global Surveyor was a global mapping mission that examined the entire planet, from the ionosphere down through the atmosphere to the surface.  As part of the larger Mars Exploration Program, Mars Global Surveyor performed monitoring relay for sister orbiters during aerobraking, and it helped Mars rovers and lander missions by identifying potential landing sites and relaying surface telemetry.
It completed its primary mission in January 2001 and was in its third extended mission phase when, on 2 November 2006, the spacecraft failed to respond to messages and commands. A faint signal was detected three days later which indicated that it had gone into safe mode. Attempts to recontact the spacecraft and resolve the problem failed, and NASA officially ended the mission in January 2007.
The Mars Orbiter Camera (MOC) science investigation used 3 instruments: a narrow angle camera that took (black-and-white) high resolution images (usually 1.5 to 12 m per pixel) and red and blue wide angle pictures for context (240 m per pixel) and daily global imaging (7.5 km per pixel). MOC returned more than 240,000 images spanning portions of 4.8 Martian years, from September 1997 and November 2006.[6] A high resolution image from MOC covers a distance of either 1.5 or 3.1 km long. Often, a picture will be smaller than this because it has been cut to just show a certain feature. These high resolution images may cover features 3 to 10 km long. When a high resolution image is taken, a context image is taken as well. The context image shows the image footprint of the high resolution picture. Context images are typically 115.2 km square with 240 m/pixel resolution.

MAUNA LOA PAINTED BY JULES TAVERNIER

The volcano 

Mauna Loa  (4,170m - 13, 680ft)  which means Long Mountain in Hawaiian, is one of five volcanoes that form the Island of Hawaii in the U.S. state of Hawaiʻi in the Pacific Ocean. The largest subaerial volcano in both mass and volume, Mauna Loa has historically been considered the largest volcano on Earth. It is an active shield volcano with relatively gentle slopes, with a volume estimated at approximately 18,000 cubic miles (75,000 km3), although its peak is about 120 feet (37 m) lower than that of its neighbor, Mauna Kea. Lava eruptions from Mauna Loa are silica-poor and very fluid, and they tend to be non-explosive.

Mauna Loa has probably been erupting for at least 700,000 years, and may have emerged above sea level about 400,000 years ago. The oldest-known dated rocks are not older than 200,000 years. The volcano's magma comes from the Hawaii hotspot, which has been responsible for the creation of the Hawaiian island chain over tens of millions of years. The slow drift of the Pacific Plate will eventually carry Mauna Loa away from the hotspot within 500,000 to one million years from now, at which point it will become extinct.

Mauna Loa's most recent eruption occurred from March 24 to April 15, 1984. No recent eruptions of the volcano have caused fatalities, but eruptions in 1926 and 1950 destroyed villages, and the city of Hilo is partly built on lava flows from the late 19th century. Because of the potential hazards it poses to population centers, Mauna Loa is part of the Decade Volcanoes program, which encourages studies of the world's most dangerous volcanoes. Mauna Loa has been monitored intensively by the Hawaiian Volcano Observatory since 1912. Observations of the atmosphere are undertaken at the Mauna Loa Observatory, and of the Sun at the Mauna Loa Solar Observatory, both located near the mountain's summit. Hawaii Volcanoes National Park covers the summit and the southeastern flank of the volcano, and also incorporates Kilauea, a separate volcano.

The painter 
Jules Tavernier was a French painter, illustrator, and an important member of Hawaii’s Volcano School.  He studied with the French painter, Félix Joseph Barrias (1822–1907). he left France in the 1870s and never  return. Tavernier was employed as an illustrator by Harper's Magazine, which sent him, along with Paul Frenzeny, on a year-long coast-to-coast sketching tour in 1873.
 Eventually, he continued westward to Hawaii, where he became quite famous as a landscape painter. He was fascinated by Hawaii’s erupting volcanoes—a subject that pre-occupied him for the rest of his life, which was spent in Hawaii, Canada and the western United States. Tavernier died on 18 May 1889 in Honolulu, Hawaii. He painted several version of the Kilauea erupting between 1880 and the end of his life.
Among the public collections holding paintings by Jules Tavernier are the Brigham Young University Museum of Art (Provo, UT), the Colorado Springs Fine Arts Center (Colorado Springs, CO), the Crocker Art Museum (Sacramento), the Gilcrease Museum (Tulsa, OK), Hearst Art Gallery (Saint Mary's College of California, Moraga, CA), the Honolulu Museum of Art, the Museum of Nebraska Art (Kearney, NE), the Oakland Museum of California, the San Diego Museum of Art, the Stark Museum of Art (Orange, TX), the Society of California Pioneers (San Francisco, CA), the Washington County Museum of Fine Arts (Hagerstown, MD) and the Yosemite Museum (Yosemite National Park).
After his death his art lived on in the hearts and homes of Hawaiians, and many more artists picked up on the volcano landscape theme he started. His Western art was mostly forgotten.
Fifty years after his death the Honolulu Advertiser remembered Jules Tavernier in December 1940 with the comment: “...to the generation which knew King Kalakaua, Tavernier recalls to mind some of the greatest paintings ever made of Hawaii volcanoes.”
At the beginning of the twenty-first century interest has reawakened in Tavernier's Western landscape art; museums are purchasing his pictures and prices for his oil paintings are increasing.
His students included D. Howard Hitchcock (1861–1943), Amédée Joullin (1862–1917), Charles Rollo Peters (1862–1917) and Manuel Valencia (1856–1935).

The slow drift of the Pacific Plate will eventually carry Mauna Loa away from the hotspot within 500,000 to one million years from now, at which point it will become extinct.

Mauna Loa's most recent eruption occurred from March 24 to April 15, 1984. No recent eruptions of the volcano have caused fatalities, but eruptions in 1926 and 1950 destroyed villages, and the city of Hilo is partly built on lava flows from the late 19th century. Because of the potential hazards it poses to population centers, Mauna Loa is part of the Decade Volcanoes program, which encourages studies of the world's most dangerous volcanoes. Mauna Loa has been monitored intensively by the Hawaiian Volcano Observatory since 1912. Observations of the atmosphere are undertaken at the Mauna Loa Observatory, and of the Sun at the Mauna Loa Solar Observatory, both located near the mountain's summit. Hawaii Volcanoes National Park covers the summit and the southeastern flank of the volcano, and also incorporates Kilauea, a separate volcano.

The painter 
Jules Tavernier was a French painter, illustrator, and an important member of Hawaii’s Volcano School.  He studied with the French painter, Félix Joseph Barrias (1822–1907). he left France in the 1870s and never  return. Tavernier was employed as an illustrator by Harper's Magazine, which sent him, along with Paul Frenzeny, on a year-long coast-to-coast sketching tour in 1873.
 Eventually, he continued westward to Hawaii, where he became quite famous as a landscape painter. He was fascinated by Hawaii’s erupting volcanoes—a subject that pre-occupied him for the rest of his life, which was spent in Hawaii, Canada and the western United States. Tavernier died on 18 May 1889 in Honolulu, Hawaii. He painted several version of the Kilauea erupting between 1880 and the end of his life.
Among the public collections holding paintings by Jules Tavernier are the Brigham Young University Museum of Art (Provo, UT), the Colorado Springs Fine Arts Center (Colorado Springs, CO), the Crocker Art Museum (Sacramento), the Gilcrease Museum (Tulsa, OK), Hearst Art Gallery (Saint Mary's College of California, Moraga, CA), the Honolulu Museum of Art, the Museum of Nebraska Art (Kearney, NE), the Oakland Museum of California, the San Diego Museum of Art, the Stark Museum of Art (Orange, TX), the Society of California Pioneers (San Francisco, CA), the Washington County Museum of Fine Arts (Hagerstown, MD) and the Yosemite Museum (Yosemite National Park).
After his death his art lived on in the hearts and homes of Hawaiians, and many more artists picked up on the volcano landscape theme he started. His Western art was mostly forgotten.
Fifty years after his death the Honolulu Advertiser remembered Jules Tavernier in December 1940 with the comment: “...to the generation which knew King Kalakaua, Tavernier recalls to mind some of the greatest paintings ever made of Hawaii volcanoes.”
At the beginning of the twenty-first century interest has reawakened in Tavernier's Western landscape art; museums are purchasing his pictures and prices for his oil paintings are increasing.
His students included D. Howard Hitchcock (1861–1943), Amédée Joullin (1862–1917), Charles Rollo Peters (1862–1917) and Manuel Valencia (1856–1935).

The mountain 

Piton de la Fournaise (Peak of the Furnace) is a shield volcano on the eastern side of Réunion island (a French department) in the Indian Ocean. It is currently one of the most active volcanoes in the world, along with Kilauea in the Hawaiian Islands (Pacific Ocean), Stromboli, Etna (Italy) and Mount Erebus in Antarctica. A previous eruption began in August 2006 and ended in January 2007. The volcano erupted again in February 2007, on 21 September 2008, on 9 December 2010, which lasted for two days and on 1 August 2015 A. An other one on 26 May 2016 ... the very last eruption just begun yesterday,  11 Septembre 2016. 

The volcano is located within Réunion National Park, a World Heritage site.

Piton de la Fournaise is often known locally as le Volcan (The Volcano); it is a major tourist attraction on Réunion island.  Due to his activity, the Piton de la Fournaise is constantly monitored by geophysical sensors (tiltmeters, extensometers, differential GPS receivers, etc.).  The data from those various sensors is sent to the Piton de la Fournaise Volcano Observatory, located in Bourg-Murat, northwest of the volcano.  The observatory, founded in 1978 following the Piton-Sainte-Rose flow, is operated by the Institut de Physique du Globe de Paris (Global Geophysics Institute of Paris), in association with CNRS ( National Institute of Scientific Resarch)  and the University of Réunion. The OVPF often publishes reports on Piton de la Fournaise's current activity via their website in French. RIGIC (the Réunion Island Geological Information Center) takes this information and translates it into English for distribution to the English-speaking scientific.

Climbing

A high quality forestry road, followed by a track (with lots of bumps), connects the highway of the plains in Bourg-Murat to the Pas de Bellecombe (Bellecombe Pass), where a parking lot and a snack bar are available to visitors.  The Pas de Bellecombe is situated over the caldera rim cliffs and offers a good point of view over the northeast part of the caldera.

A good stairway path descends from the pass to the caldera floor.  This path is closed for safety reasons during seismic events that may precede eruptions and during eruptions. White paint marks over rocks delimit a number of footpaths ascending the lava shield inside the caldera.  Visitors exploring the caldera should be in good physical condition, with hiking shoes and a supply of drinking water and food. They must be prepared to exercise caution, for the weather can change very quickly, moving from bright sunlight and heat (with risks of heatstroke) to dense fog with cold and rain. In dense fog, straying from paths is very risky. Visitors are advised to take the necessary precautions for sun, heat, cold and rain and not to stray from marked paths.  An excellent, albeit expensive, way to get a good sight of the volcano is to ride in the tourist helicopter flights offered by commercial companies on the island The lower parts of the Grand Brûlé can be visited from the N2 highway.  Lava flows that have crossed the road are indicated by signs.

Completely free access during eruptions was permitted until 1998; access has been limited since that date, being virtually banned at present.

The painter  

Jean-Baptiste Genevieve Marcellin Bory de Saint-Vincent is a French officer, naturalist and geographer, who was mainly interested in volcanology, botany and systematic.

During the las years of the 18th century (particularly agitated in France) , he learned the departure of a scientific expedition organized by the government and gets the job of chief zoologist aboard a participating corvettes then met Bernard Germain de Lacépède. Thus, after leaving the army, Jean Baptiste Bory de Saint-Vincent left Paris on September 30, arrived in Le Havre on 2 October and leaves town aboard one of the ships that captain Nicolas Baudin took  around the world from 1800 to 1804.  He stopped in Mauritius in March 1801.  From there, he reached l'Ile de la Réunion (ex Bourbon Island) where he performed in October and November 1801 ( "An X" in the Revolutionary Calendar)  the rise and the first general scientific description of the Piton de la Fournaise, the active volcano of the island.  It gives the name of the scientist Dolomieu he just learned the death to  one of the craters he describes as a nipple. It gives its own name to the  crater of the summit.  Back in France in 1802, he published Voyage dans les îles d'Afrique (Travel in african Islands). He continued his scientific career in parallel to a military career: he was elected correspondent of the Museum in August 1803 and the "correspond of  first class" of the Institute de France in the spring of 1808. In 1804, he published  Essais sur les iles fortunées  (Essay on the wealthy islands) et Voyage dans les quatre principales îles des mers d'Afrique (Travel in the four main islands of the African seas). The articles, written by international scientific luminaries, were illustrated by  lithographs printed by Duval Mercourt then Marcellin Jobard.  In 1828, he was appointed to head the commission scientific exploration of Morea, held in 1829-1830. In 1830 he appeared in an election to become a member of the Institute after the death of Lamarck. He died in 1846 а Paris and was buried in Père Lachaise Cemetery (49th division).
