GEOLOGIC HISTORY
Talang, which forms a twin volcano with the extinct Pasar
Arbaa volcano, has two crater lakes on its flanks. The
largest of these is 1 x 2 km wide Danau Talang. No
historical eruptions have occurred from the summit of the
volcano, which lacks a crater.
Historic Activity:
- Eruptions have occurred in 1833, 1843, 1845, 1876,
1963, 1967, and 1968.
- All historical eruptions from Gunung Talang volcano
have involved small-to-moderate 19th-century explosive
activity originating from a series of small craters in a
valley on the upper NE flank.
- Solfataric activity occurrs within a valley NNE of
the summit.
- The last reported eruptions were small upper NE flank
explosions in 1967 and 1968.
Recent Activity:
- Increased thermal activity began in May 1986 within
the solfatara field. The area of thermal activity has
grown in area but temperatures remain within the normal
range (92°-97° C).
- Increased temperatures in thermal areas and gas
plumes from summit were reported in Sept 2001.
