Tungurahua Volcano, Ecuador: possible lava flow

Sunday Aug 19, 2012 09:59 AM | BY: T

Thermal images taken of the lava flow and mobilized incandescent blocks tumbling down from a notch in the crater wall on the northwestern flank of the volcano Tungurahua. (S. Vallejo / IGEPN)

Current seismic signal (RETU station) with saturated tremor visible on the spectrogram (IG)
At 19h36 (local time) on 18 August, a possible lava flow from the summit crater and incandescent lava blocks continuously tumbling down were observed using thermal imagery.
The lava flow which some observers also reported seeing by naked eye is emerges from a breach in the sidewall of the crater on the upper NW flank and directed towards the Cusu gorge.
Apparently the lava flow stopped after nearly 4 hours of motion, but bad weather conditions make detailed observations difficult.
Preceding the effusion of the new flow, there had been a strong increase of activity since 16 August including seismic tremor, steam and ash emissions and loud explosions audible in nearby towns such as Ambato.
