Based on information from CVGHM, the Darwin VAAC reported that on 19 and 20 March ash plumes from Talang rose 3.4-3.9 km (11,000-12,800 ft) a.s.l. CVGHM raised the Alert Level to 3 (on a scale of 1-4).

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.
