Koryaksky (Koryak) in Russia
Yesterday in the USGS/SI update, I mentioned the current eruption going on at Koryaksky (a.k.a. Koryak). Today, the NASA Earth Observatory has some images of the plume from the Russian volcano heading out to the east over the Peninsula. The plume itself looks fairly diffuse and mostly whitish steam rather than laden with grey/brown ash. The last significant eruption from Koryaksky was a VEI 3 eruption in 1956-57 that produced ash fall and pyroclastic flows from the volcano.
One thing that is noted on the EO page is this snippet:
MODIS captured this plume days…
eklemetti | August 26, 2009The slow summer for volcanic eruptions continue. Only 11 updates in this week's USGS/SI report. Thanks again to SI's Sally Kuhn Sennert for compiling the news!
Highlights this week include (not including Kilauea) include:
Tungurahua in Ecuador produced some minor lahars on August 21 to go with steam-and-gas emissions.
Popocatépetl in Mexico produced an ash plume that reached ~8.2 km / 27,000 feet on August 20 and continued to produce steam-and-ash plumes throughout the week following.
Over on the Kamchatka Peninsula, both Koryaksky and Shiveluch produced significant ash plumes (reaching 3-5…
eklemetti | August 19, 2009Busy 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.

Some more information is coming out about the activity at Koryak (aka Koryaksky) in Kamchatka. Russian geologist Alexei Ozerov says that the activity at Koryak (note: the image in the article linked here appears to have nothing to do with Koryak) has started with more power than the last known eruption of the volcano in 1956. He also mentions that the volcano is already a danger to aviation in the area (as the closing of the Petropavlosvk-Kamchatsky Airport suggested).
We also have some great images of the volcano, showing the vent on the side of the volcano (see above). It is hard to tell…

News is filtering in that Koryak (aka Koryaksky) Volcano in Kamchatka might be heading towards an explosive eruption. The details are scarce, but it seems that a breach on the northwest slopes of the volcano might cause an explosive eruption, however, it is not clear why this is. All this talk has caused the Petropavlosvk-Kamchatsky Airport (~13 miles northeast) to close in fears of this potential activity.
Koryak is yet another potentially active volcano on the Kamchatka Peninsula, along with currently active Bezymianny, Kliuchevskoi, Karymsky and Shiveluch. The last eruption at Koryak…
