Active volcanoes / Aktive vulkaner:
Tangkubanperahu, Indonesia  

Tangkubanparahu, here from the east, forms the most prominent peak north of the city of Bandung.
The 2.084 m high summit of the volcano overlooks a broad crater complex, whose souther rim forms
the flat ridge left of the summit.

Tankubanparahu volcano blanket the area around Bandung.

Tangkubanparahu is a broad shield-like stratovolcano overlooking the former capital city of
Bandung, that was constructed within the 6 x 8 km Pleistocene Sunda caldera. The volcano's
low profile is the subject of legends referring to the mountain of the "upturned boat".
The age the caldera forming eruption exceeds the >40.000 year range of radiocarbon dating.
The rim of Sunda caldera forms a prominent ridge on the western side; elsewhere the caldera
rim is largely buried by deposits of Tangkubanparahu volcano. The dominantly small phreatic
historical eruptions recorded since the 19th century have originated from several nested
craters within an elliptical 1x1,5 km summit depression.
The position of the volcano is at 6°77 S and 107°60E

A second Indonesian volcano in addition to Talang, sprang to life on Wednesday in the wake
of a series of  terrifying quakes that have underlined theprecarious bond between the
archipelago and the violent geological forces raging beneath. However, it has not yet erupted,
It is still at level 3 in a scale of 1-4.

Tangkuban Perahu, a smouldering 2,076-metre (6,933 foot) mountain near the city of
Bandung on Java island, began rumbling overnight, prompting scientists to raise the status
of the volcano to “alert” and declare it off limits.

A day earlier, more than 20,000 people fled the slopes of the Talang volcano on Sumatra
island, as the peak spewed hot ash after being unsettled by huge tremors from the same
faultline that caused last year’s deadly tsunami.

At Java island’s Tangkuban Perahu, a popular tourist spot that has an access road leading
almost all the way to its crater, and there had been almost continuous activity overnight.

There have been hundreds of volcanic earthquakes recorded. And therefore this morning,
at 8:25 am, the status of the volcano has been raised to “alert’.

The broad summit of Tangkubanparahu volcano is seen in this aerial view
from the NW. The dashed line outlines an outer crater inside which a
younger crater complex (dotted line) was constructed. Frequent phreatic
eruptions have occured during historical time from the central cratercomplex.
Bukit Tunggul, an older volcano, forms the peak on the center horizon.
