Based on visual observations, CVGHM reported that during 18-25 June thick brown ash plumes from Talang's Main Crater rose to an altitude of 3.1 km (10,200 ft) a.s.l. Diffuse white ash plumes rose to an altitude of about 3 km (10,000 ft) a.s.l. from the South Crater. The Alert Level remained at 2 (on a scale of 1-4).
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.
