Based on information from CVGHM, the Darwin VAAC reported that on 19 and 20 March ash plumes from Talang rose 3.4-3.9 km (11,000-12,800 ft) a.s.l. CVGHM raised the Alert Level to 3 (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.
