Lliama volcano (Chile): likely false report of volcanic ash plume
VAAC Buenos Aires received a pilot report of a light ash plume between 10,000 and 25,000 ft altitude from the volcano this afternoon. However, this seems to be a false eruption report.

There are no other indications of an eruption and no ash could be seen on webcam and satellite imagery. Local press (who would pick up quickly on activity at one of Chile's most prominent volcanoes) nor SERNAGEOMIN have reported any unusual new activity. It is possible that wind has picked up dust (ash) from the volcano or that a weather cloud was mistaken for an ash plume.

The Chilean geological service SERNAGEOMIN raised the alert level of Llaima volcano from 3 to 4 on 25 April because of ‘the occurrence of earthquakes with high energy levels and tremor signals with durations of up to 20 minutes’, a volcanologist reported to a llocal newspaper. alles lesen

A new eruption started at Llaima volcano on 4 April 09. Lava fountains and stormbolian activity from the summit vents fed lava flows travelling down the slope of the volcano. ... alles lesen

It was reported that clouds had prevented visual observations of Llaima during 29 August-2 September. On 3 September, fumarolic plumes that originated from three points on the pyroclastic cones in the main crater drifted N. An explosion produced an ash plume that also drifted N; ash deposits on the N flank suggested previous emissions. On 4 September gas plumes from the main crater drifted W. Gas-and-steam plumes were emitted during 5-7 September. The Volcanic Alert Level remained at Yellow ... alles lesen

During 8-11 August, SERNAGEOMIN reported that fumarolic activity from the snow-free pyroclastic cones in Llaima's main crater was visible during periods of clear weather; resultant plumes drifted E. A 2-km long strip on the NE flank was black in color (snow-free) due to elevated temperatures. On 13 August, gas-and-ash plumes rose to an altitude of 3.3 km (10,800 ft) a.s.l. and drifted E. Later that day, incandescence from the crater accompanied the gas-and-ash emissions. ... alles lesen
