Since 1818, at least 55 eruptions have been recorded (10 of which resulted in fatalities) consisting of both lava flows and pyroclastic flows. All historical eruptions have had a VEI of 2 or 3. Semeru has been in a state of near-constant eruption from 1967 to the present. At times, small eruptions happen every 20 minutes or so.
In 2014, there are as many as 25 non-native plants in Mount Semeru National Park, which threaten the endemic local plants. The foreign plants were imported by a Dutch botanist named Van Steenis, in the colonial era. They include Foeniculum vulgare mill, Verbena brasiliensis, chromolaena odorata, and Salvinia molesta.
Mud erosion from surrounding vegetable plantations are also making problem of silting of Ranu Pane Lake, which the lake becomes smaller and shallower. Research predicted the lake will disappear in about 2025, except the kind of vegetables plantation is replaced with more ecological plantations.
Semeru is regularly climbed by tourists, usually starting from the village of Ranu Pane to the north, but though non-technical it can be dangerous. mainly because of the poisonous gases on Mount Semeru.
Autochrome process
The Autochrome Lumière is an early color photography process. Patented in 1903 by the Lumière brothers in France and first marketed in 1907, it was the principal color photography process in use before the advent of subtractive color film in the mid-1930s.
Between 1909 and 1931, a collection of 72,000 Autochrome photographs, documenting life at the time in 50 countries around the world, was created by French banker Albert Kahn. The collection, one of the biggest of its kind in the world, is housed in The Albert Kahn Museum on the outskirts of Paris. A new compilation of images from the Albert Kahn collection was published in 2008. Several images from the Albert Kahn Collection have been already published in this blog
The National Geographic Society made extensive use of Autochromes and other mosaic color screen plates for over twenty years. 15,000 original Autochrome plates are still preserved in the Society's archives.
In the U.S. Library of Congress's huge collection of American Pictorialist photographer Arnold Genthe's work, 384 of his Autochrome plates were among the holdings as of 1955.
Many photographers used it anonymously as well.

GUNUNG MERBABU BY ISODORUS VAN MENS
Gunung Merbabu (3,145m -10, 318ft) is a dormant stratovolcano in Central Java province on the Indonesian island of Java. The name Merbabu could be loosely translated as 'Mountain of Ash' from the Javanese combined words; Meru means "mountain" and awu or abu means "ash".
The active volcano Gunung Merapi is directly adjacent on its south-east side, while the city of Salatiga is located on its northern foothills. A 1,500m high broad saddle lies between Merbabu and Merapi, the site of the village of Selo, Java and highly fertile[citation needed] farming land.
There are two peaks; Syarif (3,119 m) and Kenteng Songo (3,145 m). Three U-shaped radial valleys extend from the Kenteng Songo summit in northwesterly, northeastly and southeastly directions.
Two known moderate eruptions occurred in 1560 and 1797. The 1797 event was rated 2: Explosive, on the Volcanic Explosivity Index. An unconfirmed eruption may have occurred in 1570.
Geologically recent eruptions originated from a North Northwest-South Southeast fissure system that cut across the summit and fed the large-volume lava flows from Kopeng and Kajor craters on the northern and southern flanks, respectively.
Merbabu can be climbed from several routes originating from the town of Kopeng on the north east sideside, and also from Selo on the southern side. A climb from Kopeng to Kenteng Songo takes between 8 and 10 hours.[citation needed]
An area of 57 kmІ at the mountain has been declared a national park in 2004.

GUNUNG LAWU PAINTED BY ARTHUR ELAND
Gunung Lawu ( 3,265 m - 10,712 ft)
Indonesia (Java)
In "Mountains in Indonesia", oil on canvas, 1912, Private collection
The mountain
Gunung
Lawu is a massive compound stratovolcanostraddling the border between
East Java and Central Java, Indonesia. The north side is deeply eroded
and the eastern side contains parasitic crater lakes and parasitic
cones. A fumarolic area is located on the south flank at 2,550 m. The
only reported activity of Lawu took place in 1885, when rumblings and
light volcanic ash falls were reported. The recent study provided
insights into geothermal heat flow suggesting that Mt. Lawu is still
active today.
Mount Lawu is the home of the God Parwatarajadewa(also
called Hyang Girinatha in the manuscript Serat Centhini). The New
Javanese manuscript Serat Manikmaya states that Mount Lawu is part of
the eighteen sacred mountains of Central Java, and scholars agree that
it had great religious significance to the Hindus of Java. Poerbatjaraka
stated that the original name of Lawu is Katong, which means God. The
name Katong is likely associated with the ruins of Mount Meru,
the sacred five peaked mountain and center of the universe. This
assosiation makes it likely that it is a seat of God, for which it is
named. The last mention of this name was in the reign of Bhre Kertabhumi
(1474-1478), and the first mention of Mount Lawu was in the Bhujangga
Manik in the early 16th century, which indicates the name change took
place between the 15th and 16th centuries, coinciding with the Islamic
invasion.
