Villarrica volcano (Chile): activity summary 24-31 March 2015 (strombolian activity)
Donnerstag Apr 02, 2015 11:05 | VON: T
OVDAS-SERNAGEOMIN reported that during 24-25 March gas-and-ash emissions at Villarrica decreased but the magnitude of the continuous seismic tremor slightly increased. Crater incandescence overnight was observed.
By the evening of 25 March Strombolian activity was confined to the crater and a gas plume rose 700 m above the crater rim. Seismicity fluctuated but increase overall. The lava lake had returned and was about 1,000 degrees Celsius.
During 26-27 March Strombolian activity ejected tephra out of the crater to distances of about 500 m, and a gas plume rose more than 800 m. During an overflight on 27 March scientists noted that material which measured 1,110 degree Celsius originated from two vents.
During 28-31 March a gas-and-ash plume rose from the crater and Strombolian explosions ejected tephra from the crater; several explosions starting at 2200 on 30 March, and continuing the next morning, ejected tephra 300 m above the crater and as far as 500 m from the crater onto the flanks.
The Alert Level remained at Orange (the second highest level on a four-color scale) and the public was warned to stay outside of a 5-km radius around the crater and away from drainages.

Weak incandescence from mild strombolian activity in the summit crater of the volcano has become visible at night. [mehr]
Sonntag, Mär 22, 2015
The volcano is having phases of increasingly intense, continuous ash emissions, probably caused by deep-seated strombolian activity. No or little incandescence has been visible last night. [mehr]
