During 19 November- 2 December seismicity at Talang was dominated by small explosion earthquakes. In addition, there was an increase in deep volcanic earthquakes in comparison to the previous week. During 19-25 November an increase in tectonic earthquakes was recorded. Thin plumes rose ~50 m above Gabuo Atas and Kepundan Panjang fumarole fields. The volcano remained at Alert Level 2 (on a scale of 1-4).
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.
