The Smithsonian Institution and United States Geological Survey Weekly Volcanic Activity Reports enter their second decade of chronicling what the world’s volcanoes are up to with this week’s report, which covers 29 December 2010 to 4 January 2011 and is compiled by Sally Kuhn Sennert. Some selected highlights:

  • Etna: light ashfall, incandescence, vigorous strombolian activity
  • Manam: new eruptive episode – ash plumes, some dense; incandescence; pyroclastic flows
  • Stromboli: increase in the frequency and intensity of explosions from the S1 vent
  • Machín: increase in low-magnitude volcanic-tectonic seismicity recorded

Some highlights from the last week of volcanic activity courtesy the Global Volcanism Program and Sally Kuhn Sennert, including more seismic restlessness and ash venting at Soufrière Hills and some big bangs at Stromboli:

  • Soufrière Hills: seismic swarms, ash venting, ashfall, some rumbling and roaring
  • Stromboli: two major explosive events at the ever-active ‘Lighthouse of the Mediterranean’
  • Pacaya: an explosion produces ash and tephra fall, provoking small-scale evacuations
