All times are local (unless otherwise noted)
During 11 March-16 June 2002 at Talang, seismicity was dominated by small explosion earthquakes (table 4). A thin white plume reached 50-100 m above the summit and sometimes drifted E. Hotspring temperatures were 42-64°C. As of 13 May, the Volcanological Survey of Indonesia (VSI) reported that no seismic data were available because of a broken seismograph. During April and early May seismicity had been decreasing. Talang remained at Alert Level 2 (on a scale of 1-4) throughout the report period.

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.
