SI/USGS Weekly Volcano Activity Report for 8/12-18/2009

Busy today with scouting out some field location for the class I'll be teaching this fall. Here's this week's USGS/SI Weekly Volcano Report. The report is a little more eventful than last week's, so enjoy!


Kliuchevskoi Volcano in Kamchatka, taken summer of 2009 by Theresa Kayzar.

Highlights include:

  • Three volcanoes on the Kamchatka Peninsula are currently producing ash plumes: Kliuchevskoi, Koryaksky and Shiveluch. Shiveluch has been having the most intense eruptions, but the former two are both producing ash-and-steam plumes that reach over 3 km / 10,000 feet.
  • Talang in Indonesia saws its warning level raised from 2 to 3, with a 3-km exclusion zone set to prevent tourists from getting too close.
  • Minor amounts of ash were produced by Popocatépetl, near Mexico City.
  • It seems that Pagan in the Mariana Islands had a brief eruption, as satellite observations detected a 2-hour-long "thermal anomaly" last week.
  • Reventador in Ecuador produced a new lava flow that was accompanied by seismic tremors, volcanic bombs and ash plumes.

Shiveluch volcano in Russia. Image courtesy of KVERT. Over this past weekend, Shiveluch in Kamchatka experienced a plinian eruption, producing a 7-km / 23,000 foot ash column. The NASA Terra satellite caught a great image of the ash plume over the snowy landscape of the Kamchatkan Peninsula on…
Sally Sennert from the Smithsonian Institution sent me an email to say that this week's USGS/Smithsonian Institute Weekly Volcanic Report will be delayed due to the inclement weather in the Washington DC area. She can't connect with the server, so the report can't be updated on the Smithsonian…

Theresa Kayzar took a great picture of that volcano.

I am guessing she was high up on another volcano - yet below the tree line. The clouds curling around the volcano near ground level - it just makes for a great, very unique volcano picture.

[OT] So which volcano won the Volcano Profile Poll?

I voted Karymsky because the Kamchatcka peninsula looks so beautiful - like in that photo above. :)
