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

- Continuing activity at Etna including strombolian eruptions, lava fountaining and lava flows
- Explosions at Fuego produced plumes that reached 0.6 km above the crater
- Plumes rose to 1 km above Puyehue-Cordón Caulle as low-level eruptive activity continues

Restless Tungurahua causes ash problems 6 March 2012
Posted by admin in activity reports, Ecuador, Tungurahua.comments closed
Tungurahua volcano in Ecuador is one of the world’s more active volcanoes, and it is certainly restless at the moment, with an upswing in activity and explosive eruptions being reported over the weekend. Activity continues at a ‘moderate’ level according to reports from Ecuador’s Instituto Geofísico: an explosion occurred in the early hours of Monday 5 March which produced ashfall in the Choglontus area, which lies ~13 km WSW of the volcano (IG report for 5 March 2012 PDF). Much of the region around Tungurahua has been covered in low cloud which has obscured views of the volcano: a weak emissions column in a westerly direction was visible on 5 March at an altitude of under 1 km. The bulletin for 6 March (PDF) reports the summit of Tungurahua is still obscured by cloud. Elevated seismicity has continued, with seven episodes of emission tremor and one explosion, so some eruptive activity has occurred today.
The ashfall from the current activity has been causing problems, with reports of crop damage in agricultural areas to the west of the Tungurahua.

Renewed activity at Tungurahua 4 March 2012
Posted by admin in activity reports, Ecuador, Tungurahua.comments closed
Ecuador’s Tungurahua volcano had a busy year in 2011, notably producing its biggest eruption for several years in April, and ending with a period of marked restlessness from November into January of this year including significant explosive events on 27 and 28 November 2011. Since then the level of activity has been rising and falling, with episodes of moderate activity including steam plumes and lahars throughout January and February interspersed with more active episodes involving significant ash plumes, strombolian activity and the eruption of significant quantities of incandescent material.
In bulletins issued yesterday Ecuador’s geological service, the Instituto Geofísico, reports a new upswing in activity at Tungurahua marked by the eruption of incandescent blocks, rumbling sounds and emission columns, and lava fountains reaching 500 metres above the crater. There are press reports of ashfall in nearby communities.
