Due to a decrease in seismicity at Talang during 24-28 April, DVGHM reduced the Alert Level from 3 to 2 (on a scale of 1-4) on 28 April. Visitors were still not permitted to enter within a 1 km radius of the crater.
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.
