Signs of enhanced activity at Gabuo Atas solfatara field were observed in May, when increased fuming was noted. The area of thermal activity has grown to cover ~10 hectares, but the temperatures of solfataras have remained in the normal range, between 92 and 97°C.
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.
