Gunung Gamping
Indonesia (Java) 

 In Gunung Gamping near Yogyakarta, 1853-1854, Ledien Univsersity Library 

The mountain
Gunung Gamping (250 m)  is a hill  located in the province of Jawa Timur, in the southwestern part of the country, 800 km east of the capital Jakarta, Indonesia  The top of Gunung Gamping is 534 meters above sea level ( or 250 meters above the surrounding terrain) . The width at the base is 2.7 km. The terrain around Gunung Gamping is mainly hilly. The highest point nearby is 965 meters above sea level, 7.3 km southeast of Gunung Gamping. Around Gunung Gamping, it is quite sparsely populated, with 28 inhabitants per square kilometer.  with mainly green-green deciduous forest grows.  Savann climate prevails in the area. The annual average temperature in the funnel is 21 ° C. The warmest month is March, when the average temperature is 22 ° C, and the coldest is July, at 20 ° C.  The rainy month is January, with an average of 498 mm rainfall , and the driest is August, with 33 mm rainfall. 

The artist
Friedrich Franz Wilhelm Junghuhn was a German-Dutch botanist and geologist, who studied medicine in Halle and in Berlin from 1827 to 1831, meanwhile publishing  (1830) a seminal paper on mushrooms in Limnaea.  Junghuhn settled on Java, where he made an extensive study of the land and its people.  He discovered the Kawah Putih crater lake south of Bandung in 1837.
He published extensively on his many often highly adventurous expeditions and his scientific analyses.  Among his works is an important description and natural history in many volumes of the volcanoes of Java, Bijdragen tot de geschiedenis der vulkanen in den Indischen Archipel (1843).
He completed Die Topographischen und Naturwissenschaftlichen Reisen durch Java (Topographic and Scientific Journeys in Java) in 1845 and a first anthropological and topographical study of Sumatra, Die Bättalander auf Sumatra (Batak lands of Sumatra). in 1847.
In 1849, ill health forced his return to the Netherlands.  While in the Netherlands, Junghuhn began work on a four volume treatise published in Dutch and translated into German between 1850 and 1854: Java, deszelfs gedaante, bekleeding en inwendige struktuur. Junghuhn was an avid humanist and socialist. In the Netherlands he published anonymously his free-thinking manifesto Licht- en Schaduwbeelden uit de Binnenlanden van Java (Images of Light and Shadow from Java's interior) between 1853 and 1855. The work was controversial, advocating socialism in the colonies and fiercely criticizing Christian and Islamic proselytization of the Javanese people.  Junghuhn instead wrote of his preference for a form of Pandeism (pantheistic deism), contending that God was in everything, but could only be determined through reason.  The work was banned in Austria and parts of Germany for its "denigrations and vilifications of Christianity", but was a strong seller in the Netherlands where it was first published pseudonymously.  It was also popular in colonial Indonesia, despite opposition from the Dutch Christian Church there.
Recovered from his ills, Junghuhn returned to Java in 1855.  He remained on Java until his death from liver disease in 1864.  On his deathbed in his house near Lembang on the slopes of the volcano Tangkuban Perahu just north of Bandung, Java, it is said that Junghuhn asked the doctor to open the windows, in order to say goodbye to the mountains that he loved.
In Lembang there is a small monument to his memory in a grassy square named after him planted with some of his favorite trees among which the Cinchona. A minor item of trivia playing into polemical discussions of Junghuhn is his surname, literally translated as "young chicken".
The plants Cyathea junghuhniana and Nepenthes junghuhnii are named after Franz Junghuhn.

The Mountain 
Gunung Guntur  (2, 249 m) the  Thunder Mountain in Indonesian, is a  stratovolcano, located in Kampung Dukuh village, 3 km from the capital district Cipanas and 7 km from the capital city of Garut, in West Java, Indonesia.   Its last eruption dates back to 1847.
 The ridge of the mountain has a relatively unique shape. To the east, one could see the eruptions thunder until no large trees, and only sites lava flows.  The mountain has been  often used as inspiration by the artist.
From the top of the mountain thunder, the city of Regensburg can be seen.

The mountain 
Gunung Merapi  or Mount Merapi (2,914m - 9,500 ft)  is an active stratovolcano located on the border between Central Java and Yogyakarta, Indonesia. It is the most active volcano in Indonesia and has erupted regularly since 1548. It is located approximately 28 kilometres (17 mi) north of Yogyakarta city which has a population of 2.4 million, and thousands of people live on the flanks of the volcano, with villages as high as 1,700 metres (5,600 ft) above sea level.
Smoke can often be seen emerging from the mountaintop, and several eruptions have caused fatalities. Pyroclastic flow from a large explosion killed 27 people on 22 November 1994, mostly in the town of Muntilan, west of the volcano.Another large eruption occurred in 2006, shortly before the Yogyakarta earthquake. In light of the hazards that Merapi poses to populated areas, it has been designated as one of the Decade Volcanoes....

GUNUNG GEDE BY FRANZ WILHEM JUNGHUHN


FRANZ WILHEM JUNGHUHN (1809-1864)
Gunung Gede  (2,958 m - 9,705ft
Indonesia (Java) 

Print, 1856, Leiden University Library

The mountain 
Gunung Gede or Mount Gede  (2,958 m - 9,705ftis a stratovolcano situated in West Java, IndonesiaIt contains two peaks: Mount Gede  (Big Mountain in Sundanese and Mount Pangrango. Three major cities, Cianjur, Sukabumi and Bogor, are located in the volcano complex at the east, south and northwest, respectively, along with suburban growth. Seven craters are located in the complex: Baru, Gumuruh (2,927 m), Lanang (2,800 m), Kawah Leutik, Ratu (2,800 m), Sela (2,709 m) and Wadon (2,600 m). 
Historical volcanic activity has been recorded since the 16th century. With the amalgamation and growth of Greater Jakarta with those 3 cities, dense suburban growth has engulfed the fringes of the volcano, home to roughly 4 million people. Though not listed as one of the Decade Volcanoes or thought to produce large eruptions, the huge populations nearby give a potential for severe destruction if indeed a large eruption did occur.
Gunung Gede is part of the Mount Gede Pangrango National Park.  It evolved from already existing conservation areas, such as Cibodas Botanical Gardens, Cimungkat Nature Reserve, Situgunung Recreational Park and Mount Gede Pangrango Nature Reserve, and has been the site of important biological and conservation research over the last century. In 1977 UNESCO declared it part of the World Network of Biosphere Reserves.

GUNUNG SUMBING BY FRANZ-WILHELM JUNGHUHN


FRANZ-WILHELM  JUNGHUHN (1809-1864) 
Gunung Sumbing  or Mount Sumbing (3,371m -11,060 ft
Indonesia  (Java)

In 1853-1854  - Engraving shown in Leiden University Library

The mountain 
Gunung Sumbing or Gurung Sumbing  (meaning Mount Sumbing) is a prominent 3,371 m (11,060 ft) high stratovolcano that lies across a 1400-m-high saddle from symmetrical Sundoro (3,136m) volcano in central Java. Prominent cones are located on the N and SE flanks, which is somewhat more dissected than Sundoro. An 800-m-wide horseshoe-shaped summit crater breached to the NE is partially filled by a lava dome that fed a lava flow down to 2400 m elevation. Emplacement of the dome followed the eruption of extensive pyroclastic flows down the NE flank. 
The only report of historical activity, in about 1730 CE, may have produced the small phreatic craters found at the summit. 
The announcement of an eruption in the Smithsonian/USGS Weekly Volcanic Activity Report (30 July-5 August 2008) was later found to be false. The Darwin Volcanic Ash Advisory Center (VAAC) noted that a pilot reported an eruption plume from Sumbing on 1 August 2008. The plume allegedly rose to an altitude of 4.9 km and drifted W. However, ash was not identified on satellite imagery. Center of Volcanology and Geological Hazard Mitigation (CVGHM) observers at the local observatory saw only non-eruptive processes at the volcano, and they noted brush fires in September and October. A common problem in this active region occurs when drifting plumes become linked to the wrong volcano. After discussing the field observations, both Darwin VAAC and Indonesia's CVG
M concluded the report was in error.  Ashes was not identified on satellite imagery.
