CVGHM raised the Alert level for Talang from 2 to 3 (on a scale of 1-4) on 29 November based on visual observations and seismicity. Ash and steam plumes from multiple craters rose to altitudes of 3.1-4.1 km (10,200-13,500 ft) a.s.l. during 27-29 November. A strong smell of sulfur dioxide gas was also reported. Visitors and tourists were advised not to go within a 3-km radius of the summit.

Geological Summary. Talang is part of a large volcanic edifice just NW of Dibawah Lake. An older volcanic peak, Pasar Arbaao, is ~1.5 km W. The steep-sided Talang cone exhibits fumarolic activity but has no crater; it appears to have grown within a larger caldera. Recorded 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 NE flank.
