The Global Volcanism Program has put together a bumper Weekly Volcanic Activity Report for 8-14 September 2010. Sally Kuhn Kennert of the GVP compiled the report. Some highlights:

  • Nevado del Huila: alert level raised following increase in seismicity and gas/ash emissions
  • Soufrière Hills: several small-to-moderate pyroclastic flows descended the dome and took parts of it down with them
  • Arenal: rumbled its way through August with gas emissions, strombolian eruptions and avalanches
  • Sinabung: threw ash plumes up to 4.3-4.6 km altitude
