The latest Smithsonian Institution and United States Geological Survey Weekly Volcanic Activity Report has been published by the Global Volcanism Program, covering the week 14-20 March 2012. The report is compiled by Sally Kuhn Sennert. Among the highlights of this week:

  • A plume, probably water vapour, seen from Iliamna, where seismicity remained elevated
  • Seismicity decreased at Nevado del Ruiz but significant gas emissions continued
  • Etna continued lively with lava flows and fountaining, and strong ash emission
  • Daily explosions at Shiveluch produced plumes which reached 3-5 km altitude

Emissions from Villarrica? 7 September 2010

Buenos Aires VAAC (home page; message archive) issued three advisories on 4 and 5 September 2010 reporting emissions from Villarrica volcano in Chile: on 4 September a thin ash plume, very light, was identified extending 60 nautical miles NE of the volcano (4 September 2130Z), and on 5 September continuous emission was reported, although it was noted that low clouds were hampering observations (5 September 0500Z). In each case the source of the information was GOES-12 satellite data. No further reports have been issued, and this activity remains unconfirmed.

(The Villarrica Visual Observation Project have a live webcam for Villarrica. There are also four Villarrica webcams accessible from the Observatorio Volcanológico de los Andes del Sur home page, although they do not always show up-to-date images.)

Chile: alert level raised at Llaima 6 March 2010

Posted by admin in activity reports, Chile, Llaima, Villarrica.

The Chilean state geological service SERNAGEOMIN carried out an overflight of Llaima volcano on 4 March, and in the light of the observations made have raised the alert level for Llaima from Yellow Level 3 to the slightly higher Yellow Level 4.

A bulletin issued on 5 March reports that there has been no major change in the activity or morphology of Llaima since the last analysis on 21 February (although the rate of gas emissions, mainly sulphur dioxide, has increased), there have been large rockfalls on the slopes and some cracking of the ice on the northern and northwestern flanks, ‘possibly due to the powerful movement generated by the earthquake of 27 February 2010). The bulletin also suggests that swarms of tectonic quakes near Llaima have been caused by the fault system responding to the 27 February earthquake. Within the volcano, ‘an increase in the amplitude and duration of seismic activity (tremor)’ , and seismic signals ‘suggesting movement of fluids through minor cracks of a superficial character’, have been detected since the afternoon of 4 March.

This seismic activity has led SERNAGEOMIN to raise the alert level to Yellow Level 4, and to recommend an exclusion zone of 4 km radius aroud the volcano. ONEMI have more details of the alert level for Llaima and the surrounding area in a bulletin issued today.

There are some suggestions in the (Argentine) press that Villarrica volcano has also had its alert level raised, but there is no confirmation of this from SERNAGEOMIN or OVDAS, or in Chilean press reports. The most recent SERNAGEOMIN verdict on Villarrica is in a report on the volcanic chain between San Fernando and Puerto Montt, also issued on 5 March, which describes its current behaviour as ‘normal fumarolic activity’. This morning’s webcam views seem to show fresh ash on Villarrica’s upper slopes, and incandescence has been visible from the crater at night. (More on Villarrica later.)

Chilean volcanoes: all quiet after the earthquake, reports SERNAGEOMIN 5 March 2010

Villarrica volcano 5 March 2010 (OVDAS Pucon webcam)
Villarrica volcano from the Pucón webcam, 5 March 2010 (OVDAS).

In the wake of the M8.8 earthquake of 27 February, which led to speculation about the quake’s possible effects on the local volcanoes, the Chilean state geological service SERNAGEOMIN carried out an evaluation of activity at the volcanoes that are currently monitored in Chile. On 3 March a special volcanic activity bulletin was issued reporting that there is nothing unusual going on at any of the monitored Chilean volcanoes: ‘the levels and characteristics of seismic activity at Llaima, Villarrica, Chaitén, Mocho-Choshuenco, Osorno, Carrán, Calbuco and San Pedro volcanoes have shown no significant changes associated with the seismic event and activity is currently stable’. The caldera webcam at Chaitén ‘shows that the dome remains stable’, and the cameras at Llaima ‘show no significant changes in the fumarolic activity or the morphology’ of the volcano. The Villarrica webcams show ‘no major morphological change in its surface’, and visual observations of Osorno, Calbuco and Yate ‘show no abnormal situations’. (Chilean volcano webcams can be accessed via the OVDAS website.)

An overflight of Villarrica and Mocho-Choshuenco volcanoes took place on 28 February, to ‘evaluate possible changes both in activity and in glaciers and flanks’. The overflight revealed a gas and water vapour fumarole at Villarrica: this activity is described as ‘within the normal state’ of the volcano. No activity was seen at El Mocho volcano. The bulletin also notes the following observations:

The icecap on Villarrica volcano showed some new cracks and fissures on the flanks of the principal cone near the summit, caused by the 27 February earthquake, although the dimensions were smaller than those routinely present in the icecap. In addition, some small falls of ice were observed on the south flank and a small snow avalanche on the north-west flank. In the upper part of the cone of Villarrica volcano and on the north, north-west and west flanks abundant falls of rock from the summit onto the icecap and, locally, on escarpments of the flanks. In the case of Mocho volcano, small cracks were observed only on the south-east flank of the cone, the rest of the icecap showed no changes.

The OVDAS Pucón webcam shows Villarrica producing a faint fumarole this morning (see picture above).
