According to DVGHM, the eruption that began at Talang on 12 April ended on 14 April. During 14-17 April, the intensity of the activity at the volcano decreased so DVGHM reduced the Alert Level from 4, the highest level, to 3. People were permitted to return their homes near the volcano, but no one could enter within 1 km of the summit.
Geologic Background. 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.
