Tungurahua Volcano, Ecuador: possible lava flow

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.
