Ebeko
eklemetti | July 8, 2010So, 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…
eklemetti | October 29, 2009The SI/USGS GVP site is back up and running - and they've posted a new weekly volcano activity report. Enjoy!
Highlights include:
Nevado del Huila in Colombia has been showing signs that a new eruption might be starting. Seismicity has increased and minor ash fall has been reported, leading to an increase in the alert level at the volcano to "orange" (high).
Ebeko in the Kuril Islands off Russia and Japan produced a ~8.8 km / 29,000 foot ash plume.
Thermal images of the crater at El Reventador in Ecuador show that hot material is filling in the dome complex - this followed ash-and-steam…
eklemetti | May 6, 2009All the eruptions fit to print from the Smithsonsian/USGS GVP Weekly Report.
A few highlights (not including Redoubt, Rinjani and Slamet):
Multiple ash plumes from Galeras (Colombia), some producing noticeable ash fall up to 35 km from the vent.
The Alert Level at Anak Krakatau, Indonesia was raised to 3 (out of 4) after a sharp increase in the number of explosions.
The Alert Level at Cleveland in Alaska was lowered from Yellow to "Unassigned" (no Green for Cleveland as there is no real-time seismic network for the volcano, thus no "background levels" to compare.)
Ebeko in Russia continues…
eklemetti | April 8, 2009Your weekly dose of volcanic activity. As a sidenote, you can now get placemarks for the weekly activity report via Google Earth. Select "Google Earth Placemarks" from the SI / USGS Weekly Volcanic Activity Report page.
Highlights of this week's report:
New explosions at Ebeko. See my article today for more details.
More evidence of increased activity at Nyamuragira and Nyiragongo, Congo. One interesting note is that scientists from the Goma Volcano Observatory noted that earthquake swarms usually precede eruption by 3-5 months.
I've seen very little news about this, but Pacaya in Guatemala…

To me, one volcanic arc about which I wish I knew more is the Kuril-Kamchatka arc. I'm well aware of how active it is, with giants composite volcanoes like Bezymianny, Koryak, Klyuchevskoi and many, many others. This arc of volcanoes, although in a sparsely populated part of the world, is important to monitor due to its proximity of air travel lanes to Asia. So, any time I find out a volcano in this area - usually one that I was previously unfamiliar - erupted, I am excited.
Today's example: Ebeko. Never heard of it. Yet, it is…
