Villarrica volcano (Chile): paroxysm with lava fountains and tall ash plume
Tuesday Mar 03, 2015 17:39 PM | BY: T
Activity increased to a paroxysmal eruption this morning, as strombolian explosions merged into sustained tall lava fountains several hundreds of meters tall, feeding lava flows on the upper slopes of the volcano.
The ash plume rose approx. 3 km above the volcano and caused moderate ash fall in nearby areas. Red alert was declared in the municipalities of Villarrica, Pucón and Curarrehue in the La Araucanía region, as well as in Panguipulli in the Los Ríos region. More than 3300 people were evacuated.

Magma has reached the surface of the inner summit crater. Strombolian activity has formed a new small cone containing a small lava lake in its open vent. This followed a strong increase in volcanic tremor to about 20 times background level starting since Thursday. Glow from the volcano's top has become visible at night. ... [more]

Increasing activity at the volcano was reported by the Projecto Observación Visual Volcán Villarrica (POVI), suggesting that deep-seated strombolian activity has resumed in the summit crater. ... [more]

According to Projecto Observación Visual Volcán Villarrica (POVI), satellite images of Villarrica acquired on 25 July revealed a weak thermal anomaly. On 29 July observers photographed the crater and described a thermal anomaly on the S edge of the crater rim, in the same area from which a lava flow originated on 29 December 1971. They also heard deep degassing sounds. A second photograph showed a diffuse gas plume rising from the bottom of the crater, and ash and lapilli on the snow on the inner crater walls. ... [more]

Terrestrial and satellite observations confirm that for about 2 weeks weak explosive activity deep within the summit crater has resumed and indicates that magma might have begun to rise again within the volcano. ... [more]
