The USGS/Smithsonian Weekly Volcano Report, with news from Guatemala, Colombia, PNG and more!

Before it gets lost in the mists of time/finals, here is the weekly volcano report brought to us by the USGS and the Smithsonian Global Volcanism Program.

Highlights (not including Mayon, Soufriere Hills or Piton de La Fournaise):

  • Fuego in Guatemala produced ash plumes that reached 4.1-4.7 km / 13,500-15,400 ft along with avalanches of volcaniclastic debris.
  • Also in Guatemala, lava flows erupted from Pacaya, traveling hundreds of meters from the main vent area.
  • Manam in PNG produced an 3 km / 10,000 foot ash plume as part of its renewed activity this year.
  • The lava dome on Nevado del Huila in Colombia continues to glow – and produce significant ash, one with a plume that reached 7 km / 23,000 feet.
