CVGHM raised the Alert level for Talang from 2 to 3 (on a scale of 1-4) on 29 November based on visual observations and seismicity. Ash and steam plumes from multiple craters rose to altitudes of 3.1-4.1 km (10,200-13,500 ft) a.s.l. during 27-29 November. A strong smell of sulfur dioxide gas was also reported. Visitors and tourists were advised not to go within a 3-km radius 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.
