PVMBG reported that during 1 January-18 March diffuse white plumes rose at most 200 m above Talang’s Gabuo, Utama, Selatan, and Kapundan Panjang craters. Seismicity was low, no deformation was detected, and water temperatures had not significantly changed. On 20 March the Alert Level was lowered to 1 (on a scale of 1-4). Visitors and tourists were warned to stay away from the craters.
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.
