Here is the latest Smithsonian Institution and United States Geological Survey Weekly Volcanic Activity Report which covers the week 29 June – 5 July 2011, and is compiled by Sally Kuhn Sennert. Some of the highlights:

  • Kliuchevskoi: eruption produces a plume to 7 km altitude
  • Nabro: lava flows remain hot, brown ash plume rising from vent
  • Puyehue-Cordón Caulle: eruption continues, with active lava flows, and low white/grey plumes
  • Soputan: an apparent strombolian eruption produced 6 km plume and ashfall

The Smithsonian Institution and United States Geological Survey Weekly Volcanic Activity Report has been issued for the week 25-31 May 2011. The report is compiled by Sally Kuhn Sennert. Notable volcanic events this week include:

  • Dieng Volcanic Complex: evacuations following increase in gas emissions and seismic activity
  • Grímsvötn: an eruption characterized by explosive activity and ash plumes, with limited ashfall
  • Kilauea: the level of the Pu’u’O’o lava lake continued to fluctuate
  • Taal: water temperature, acidity and water level all rose in Taal’s Main Crater Lake, and there was an increase in seismic activity

Increased seismicity detected at Taal 30 September 2010

Posted by admin in activity reports, Philippines, Taal.

The highly active Philippine volcano Taal, situated on the island of Luzon, had a restless summer this year: the alert level was raised by Phivolcs on 8 June 2010 following earthquake swarms and increased steam emissions (further detailed coverage from Eruptions here and here), and was then lowered again on 2 August when Taal appeared to calm down somewhat.

Phivolcs is now reporting a renewed increase in seismic activity at Taal, although observations at the Main Crater and New Eruption areas of the volcano ‘indicated no anomalous observations in the thermal and surface manifestations of both areas’. The alert level has not been changed and remains at Level 1, but the restrictions on approaching the volcano remain in place.

A Philippine news story on Taal also notes that Phivolcs has detected four tremors around Mayon in the last 24 hours.

References to volcano alert levels on this blog are not authoritative and are not necessarily up to date. You should always check with official sources for the latest alert levels.
