So, I’m a little late with this thanks to a little hiatus, but I thought I would post the latest GVP Weekly Volcanic Activity Report. Thanks again to the Smithsonian, USGS and especially Sally Kuhn Sennert!

Some highlights include:

  • There were more ash explosions spotted at Ebeko in Kamchatka, producing ~1.8 km (5,900 foot) ash columns. This activity prompted KVERT to raise the Alert Status to Yellow. This goes along with news from a pile of other Kamchatka/Kuril Island volcanoes: Gorely, Tiatia, Karymsky, Kliuchevskoi and Shiveluch.
  • More activity at Arenal in Costa Rica – its almost always busy – including strombolian activity shaking windows up to 4 km from the vent.
  • Over in Hawai`i, activity at Kilauea continues, with the lava lake in the summit Halema`uma`u Crater and the growth of several rootless shield vents on the East Rift Zone.
  • Finally, light ash fall was observed around Soufriere Hills on Montserrat for the first time since February of this year – coincident with some seismicity underneath the volcano. Alert Status remains at 3 for the volcano.
