The Smithsonian Institution and United States Geological Survey Weekly Volcanic Activity Report, compiled by Sally Kuhn Sennert, has been issued for the week 1-7 June 2011. It’s been a lively volcanic week – highlights include:

  • Dieng Volcanic Complex: carbon dioxide emissions and seismicity both remain elevated
  • Popocatépetl: ash plumes reaching altitudes between 1 and 3 km create ashfall in nearby regions
  • Puyehue-Cordón Caulle: an eruption began on 4 June following intense seismicity
  • Kilaeua: two lava lakes were active during 1-7 June

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
