The 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 least 7.3 km (24,000 feet) tall.
  • Mexico’s Popocatépetl produced one of the larger explosions it has experienced over the last year on June 8, producing an ash plume that reached 8 km (27,600 feet).

    IMo forecast for Eyjafjallajökull (Translated by Google Translator)
    High precipitation forecast and risk aurflóðum – recorded at 09.06.2010. 17:10
    The night is predicted up to 40 mm of precipitation Eyjafjallajökull. It is expected that most of rain during the period between at. 5 and 9 in the morning. Under these conditions the risk of ash and the Eyjafjallajökull can crawl down the channels and rivers that flow south from the hills. This is mainly for Svaðbælisá, washed and Kaldaklifsá but also by such floods can come down Holtsá, Miðskálaá and Ira.

    So, picking up a subject from the Mt. Baker posting, what is the name of the volcano in the background of the HAARP photo in the wikepedia article?

    # @Doug McL – I had to do some research on this, but my guess goes to Mt. Sanford, but let’s wait and see what are others’ guesses. 🙂

    I think this is only preventive. Remember it is been monitored since only a few months ago:

    @Renato – you’re right this is Mt. Sanford (in the upper left of the HAARP image). Sanford is part of the Wrangell volcanic belt in eastern Alaska a few hundred km northeast of Anchorage. It is a large, hulking shield volcano apparently made mostly of andesite and dacite – similar to those of the stratovolcanoes in the Aleutians or the Cascades despite its shield morphology. On the right horizon is Mt. Wrangell, yet another unusual andesitic shield.

    I am no expert, but i have noticed that when there is a large earthquake in Vanuatu there is a large one on the west coast.. so this i a test and a log so we all can see if there is a conection.. OK

    So, what’s this I’m reading that Chaitén in Chile erupted violently only 320 years ago (according to Luis Lara of Sernageomín)? Whatever happened to “dormant for 9000 years”? A bit of an oopsie there, I guess.

    #5 @renee Thanks for the info, but remember this blog has a time lag of circa -4 hours to UTC.

    #3 @Doug #8 Thanks for posting the quiz. It was amusing to look for the answer and I learned a lot about volcanoes in Alaska (my knowledge didn’t go beyond Redoubt, Novarupta, Cleveland and two or three others.) Keep more coming!! 🙂

    #11 @mjkbk – Yes, it’s true. The link to the information has been posted before by Guillermo. Chaitén has been upgraded to one of the 15 more dangerous volcanoes… from Chile! (Thanks again Guillermo!)

    Interesting upswing on all 5 Helicorders and increased activity on Jon Frimmans.

    Thanks for the photos Ems, they give a really good sense of scale and environment. Shame about the blade of grass!

    Yes, I clearly didn’t know what I was taking pictures of back then! In picture 2 the island is slightly more visible on the left of the pic

    Eyjafjallajökull, Kliuchevskoi and Popocatépetl: The theme of next year’s national spelling bee should be volcanoes!
    Especially if you throw in the Hawaiian ones.
    Erik, you should have a search here for the volcano name that is the most difficult to spell.

    I’ll put in a vote for another difficult to pronounce-and spell-Icelandic (shield) volcano:

    Have been rather busy this week and there has been lots here to catch up on – thanks Erik and everyone, interesting stuff!

    Has there been a discussion, recently, on the earthquake swarm which seems underway for Grimsnes (?) listed as a fissure/crater rows volcano in the WVZ? Any interesting data?

  23. #23 Gordon

    I can offer Pululahua, looks easy but lots of opportunity for confusion.

    @23 Gordon, that’s the thing about the Hawaiian volcanoes as well.

    Other nominees are Chigniagak and Quezaltepeque

    Is Katla waking up? There’s a swarm of small quakes there…

  27. #27 Erik Klemetti
    June 12, 2010

    @26 – Again, for the Katla-worriers: The # and depth of quakes at Katla suggest to me that Katla is not waking up. These quakes strike me as near-surface seismicity related to faults or ice in the caldera. If we start seeing lots (tens to hundreds per day) quakes starting at depth (greater than 5 km), then we can start talking Katla. Until then, the seismicity at Katla is likely benign (volcanically-speaking)
