eklemetti | June 21, 2010Africa is threatened by "scorching hot blobs of magma" according to the CSM.
Nothing like some fabulous headlines to make your day.

Oh my! Yes, again, it seems that the many people in the media seem to be very confused about the nature of magma when it is underground - always expecting giant vats of swirling, molten magma rising up to destroy us all. Very few have a good sense of the real state of the Earth's mantle - mostly solid. The article is in fact about a recent study…
eklemetti | June 20, 2010News for Monday!

A couple pieces of news from two Russian volcanoes on the Kamchatka Peninsula: (1) last week's report of activity at Gorely appears to be semi-substantiated with new photos on the KVERT website (Russian). The images from June 6 and 12 (2010) shows steam plumes coming from the volcano - one as tall as 500 meters. Now, this doesn't imply that an eruption occurred, but it might suggest activity on on the upswing. KVERT…
eklemetti | June 18, 2010This week went fast, didn't it?
The Baekdu caldera along the North Korean/Chinese border.
The NASA Earth Observatory have been giving us a steady diet of volcanic plumes over the last week, including PNG's Ulawun, Russia's Sarychev Peak (a very faint plume), both an ASTER and Terra image of the summit region at Kliuchevskoi and finally a mix of plume and clouds over PNG's Manam volcano.
I wanted to also mention a brief article I ran into on the Changbaishan/Baekdu caldera along the Chinese and North Korean border. Although short on specifics, this article mentions a number of interesting (…
eklemetti | June 17, 2010Have guests in town, so I'm a little busy, but you can hopefully keep entertained with the latest Smithsonian/USGS Global Volcanism Program Volcanic Activity Report.
Chile's Melimoyu volcano.
The highlights (not including Taal and Eyjafjallajökull) include:
Alaska's Cleveland volcano has been reduced to and alert status of "unassigned" (used when a volcano is not closely monitored so AVO doesn't know what exactly is "background") after a few weeks of activity. The same was done for the submarine volcano south of Sarigan in the Marianas Islands after no signs of activity since the eruption a…
eklemetti | June 14, 2010The crater lakes at the summit of Gorely volcano in Russia.
Possibly lost in the vuvuzela noise, but Eruptions readers over the weekend noted that Gorely on the Kamchatka Peninsula in Russia had its first eruption in over 20 years. The Russian media has a brief report mentioning that the volcano produced an ash plume that "stretched over a hundred kilometers" (horizontally). The plume was causing some disruptions of local air travel and threatening a geothermal plant, but no real other details beyond that were offered. So far, there has been no update about the possible eruption on the KVERT…
jgoldman | June 14, 2010I've decided I want to cover some recent research on social cognition in domesticated dogs. But first, we need some background. So here's a repost from the old blog.
Today I want to tell you about one of my most favorite studies, ever, of animals. Are you ready? It's a FIFTY YEAR LONG longitudinal study of captive silver foxes in Russia. Gather around, pour yourself a cup of your favorite beverage, get comfortable, and enjoy storytime.

eklemetti | June 9, 2010The latest update from the Smithsonian/USGS Global Volcanism Program!
Highlights (not including Taal, Eyjafjallajökull and Bezymianny) include:
Another thermal anomaly was spotted on an Kuril Island volcano - this one being Tiatia. The volcano has no seismic monitoring network, so the thermal anomaly is all that has been observed.
Lava flows and strombolian explosions continue at Guatemala's Pacaya. Some of the explosions have launched bombs hundreds of meters into the air.
Kliuchevskoi was another busy Russian volcano, with a large thermal anomaly and ash explosions that produced a plume at…
laelaps | June 7, 2010In the part of suburban New Jersey I grew up in, almost every other school took the cougar for its sports team mascot. There were the Carl H. Kumpf Middle School Cougars, the Cranford High School Cougars, and the Kean University Cougars, among others. Nevermind that cougars were extirpated from the state long ago - they were a top choice as symbols of the agility, cunning, and ferocity sports teams like to believe they channel. The use of such totems extends beyond sports. Exxon tells us we can "put a tiger in the tank" by using their fuel, and many people adorn themselves with clothing or…
eklemetti | June 3, 2010The level of news-frenzy on some of the recent volcanic eruptions has died down, but if you're looking to see information on the many rumbling going on worldwide, look no further. Here is this week's Volcanic Activity Report put together by Sally Kuhn Sennert of the Global Volcanism Program.
Highlights - not including Pacaya, Yasur, Tungurahua and our friend in Iceland - include:
The eruption in the Marianas apparently came from South Sarigan volcano - at least according to the best guess by folks who work in the Marianas. This submarine volcano apparently shows evidence of young lava flows,…
eklemetti | June 1, 2010Tungurahua in Ecuador erupting on May 31, 2010.
Two volcanoes along the edge of the north Pacific had explosive eruptions over the weekend. We have some more details on both of the eruptions, so I'll pass them on:
Bezymianny
KVERT is excited because they claim to have predicted the explosive eruption of Bezymianny almost to the day. They had been closely monitoring the volcano and issued this statement on May 20:
According to satellite data by AVO and KVERT staff, a temperature of
the thermal anomaly over the lava dome of Bezymianny volcano began
increasing from May 19 (from -1 (9:49 UTC) to…
eklemetti | May 31, 2010Undated image of Bezymianny in Kamchatka.
Eruptions reader M. Randolph Kruger just let us in on a significant eruption at Bezymianny in Kamchatka. The AVO/KVERT alert for the volcano suggests a fairly significant explosive eruption that might cause some snarls in the international air travel over the Kamchatka Peninsula. The KVERT statement:
A strong explosive eruption of Bezymianny volcano occurred from 12:34 till 12:50 UTC on May 31, according to seismic data. Ash fall in Kozyrevsk village is continuing. The volcano obscured by clouds. A big ash cloud remains over Kamchatka at present (NOAA…
lborkowski | May 24, 2010The New York Times' Clifford J. Levy reports on violence against at journalists investigating corruption in the Moscow suburbs:
Mikhail Beketov had been warned, but would not stop writing. About dubious land deals. Crooked loans. Under-the-table hush money. All evidence, he argued in his newspaper, of rampant corruption in this Moscow suburb.
"Last spring, I called for the resignation of the city's leadership," Mr. Beketov said in one of his final editorials. "A few days later, my automobile was blown up. What is next for me?"
Not long after, he was savagely beaten outside his home and left…
eklemetti | May 20, 2010The latest Weekly Volcanic Activity Report from our friends at the Smithsonian Global Volcanism Program and the USGS.
Highlights (not including Eyjafjallajökull - you can check the latest IMO update on that eruption and the latest VAAC ash advisories.):
Villarrica in Chile was raised from Alert Level 1 to 2 by the Chilean SERNAGEOMIN after an increase in seismicity, a rise in the lava lake levels at the summit and more vigorous fumarolic activity.
In the first update in a while, a small ash plume was noticed at Chaiten in Chile, rising to ~1.8 km (8,000 feet) from the new domes.
Karymsky in…
eklemetti | May 12, 2010Ah yes, a reminder that there are other volcanoes erupting around the world than Eyjafjallajökull - but yes, it is true! Here is the latest USGS/Smithsonian Global Volcanism Program Weekly Volcanic Activity Report!
Highlights (not including Iceland) include:
Another volcano in the Kuril Islands of Russia is showing signs of, well, something. Ketoi was noticed to be experiencing increased fumarolic activity according to satellite images. Ketoi hosts a Pleistocene caldera but has had three historic eruptions over the last few centuries, most recently in 1960, and all of which were explosive…
eklemetti | May 6, 2010Grading grading grading!
A webcam capture of the eruptive plume from Eyjafjallajökull on the morning of May 6, 2010.
News:
A quick update on the Eyjafjallajökull eruption: The volcano has been producing an impressive ash plume over the last day (see image above). The current ash plume is reaching 5.8-6 km height (19-20,000 ft) - and causing some trouble over Ireland and Scotland. However, much of airspace closed yesterday has reopened (for now). You can see two new images of the ash plume over at the NASA Earth Observatory. As for the continued fallout from the ash plume from April, British…

As a certain famous Icelandic native would say, "there is more to life than this."
Some other volcano news from around the world:
The situation at Gaua in Vanuatu is worsening. Ash from the current eruption is contaminating water and food supplies on the island. Authorities are planning on evacuating 3,000 people from the island if the eruption that started in 2009 gets worse, but there has already been significant ash fall, mudflows and explosions.
Shiveluch on the Kamchatka Peninsula in eastern Russia continues to…
eklemetti | April 7, 2010Actually, no the volcanoes aren't from space, but pictures of the volcanoes were taken from space. The NASA Earth Observatory has posted three more gems of volcanic activity taken by one of the fleet of earth imagers in orbit:
A recent image of Chaiten taken by EO-1. Image courtesy of the NASA Earth Observatory.
There is a great image of the busy Kamchatkan Peninsula, where four volcanoes are seen erupting in a single image - Kliuchevskoi, Bezymianny, Shiveluch and Karymsky. The plume from Karymsky is especially prominent as a grey streak above the white snow of the Russian winter (albeit it…
eklemetti | March 12, 2010Leaving for Death Valley tomorrow - I'll be sure to take some pictures of Ubehebe Crater and the volcano at the Mirage. This will likely be the last new post until about a week from now, but look for the Erta'Ale Volcano Profile, maybe a new Mystery Volcano Photo and I'll leave a thread open for any new volcano news.
Colima in Mexico.
Eruptions reader Tim Stone sent me this image from Japanese astronaut Soichi Noguchi's Twitpic feed - it is a stunner of the caldera on Jebel Marra in Sudan. The only known historical eruption for this volcano was ~2000 BC within the Deriba Caldera, but it has…
eklemetti | February 25, 2010The flu has retreated and I'm getting back on track. Huzzah!
I'll get back to the blog by posting this week's new USGS / Smithsonian Institution Global Volcanism Program Weekly Volcano Report. Looks like some interesting stuff in it ...
Looks like there were some small eruptions from Oldoinyo Lengai in Tanzania. The volcano is one of the few (only active?) carbonatite volcanoes in the world, erupting a lava composed primarily of calcium carbonate and sodium minerals with very little silica. It leads to the odd lava that erupt black (and cool ~ 500C) and cool to white, making it one of the…
