Weekly Report (6 July-12 July 2005)



0.979°S, 100.681°E; summit elev. 2575 m

All times are local (unless otherwise noted)

Small phreatic eruptions occurred at Talang on 2 and 3 July. The eruptions occurred at the main crater, and a crater on the volcano's S slope. Ash columns reached 300-500 m above the volcano (10,500-11,100 ft a.s.l.). Gabuo Atas, Gabuo Bawah, and Kapundan Panjang craters on the volcano's N slope emitted steam to low altitudes. Talang remained at Alert Level 2 (on a scale of 1-4). Visitors were not permitted to enter within a 1 km radius of the active craters.

Geological Summary. Talang, which forms a twin volcano with the extinct Pasar Arbaa volcano, lies ESE of the major city of Padang and rises NW of Dibawah Lake. Talang has two crater lakes on its flanks; the largest of these is 1 x 2 km wide Danau Talang. The summit exhibits fumarolic activity, but which lacks a crater. Historical eruptions have mostly involved small-to-moderate explosive activity first documented in the 19th century that originated from a series of small craters in a valley on the upper NE flank.
