CVGHM lowered the Alert Level at Talang to 2 (on a scale of 1-4) on 14 December based on visual observations and a decrease in the number of earthquakes. During 7-10 December, observations of the summit were limited by inclement weather. On 11 December, "smoke" rose to a maximum altitude of 3.3 km (10,800 ft) a.s.l. from the Main crater. Plumes were also observed from South crater and Gabuo Atas solfatara field. Visitors were advised not to go within a 2-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.
