  • Details on the Tongan Eruption
    Now that people have been able to get a better look at the are about Hunga Tonga Hunga Ha'apai, we've been able to get a better idea of what sort of eruption occurred. The explosions and ash/tephra from the eruption have all but wiped out life on Hunga Ha'aapai, as the island contains one of ...

  • Rooster tails and new islands (and video, too)
    Mixing volcanoes and oceans seem to always produce exciting results. Whether it is something as simple as the ocean entry of a lava to something as impressive as a new island emerging, formed by volcanic eruption. Back in the 1960s, a previous unknown undersea volcano off the coast of Iceland erupted to form the island ...

  • Tongan eruption disrupting flights
    The eruption of Hunga Tonga Hunga Ha'apai volcano in Tonga looks to be a big one. Keleti Mafi, head of the Tongan geological service, calls this "a very significant eruption, on quite a large scale", which is no surprise considering some of the spectacular picture we saw of the eruption yesterday. In fact, the eruption ...

  • New Eruption in Tonga
    Image from keizo/weblog Hunga Tonga-Hunga Ha'apai (how's that for a name?), a shallow seamount in Tonga, appears to have erupted. An air passenger snapped some pictures of an eruption occurring in the ocean between the Tongatapu and Vava'u and pilots in the area report that (unsurprisingly), the feature is new. Hunga Tonga-Hunga Ha'apai - at least the ...

  • Move over Redoubt ... Okmok shows signs of life
    Count this as your mini-update for Redoubt, with the news being no news. Even AVO seems a little bored with Redoubt lately (not to say they aren't watching it as vigilantly as ever) as their last three updates have been exactly the same: Redoubt volcano has not erupted. Seismicity is low, but above background levels and ...

  • Redoubt continues its holding pattern
    A week ago, if you asked around, I'm sure most people would have thought Redoubt would have erupted by now considering all the seismicity and melting that was seen at the end of last week. However, volcanology is not an exact science, and here we are continuing to watch Redoubt tease us with signs of ...

  • Redoubt on alert
    Eruptions reader Ross was very right in pointing out that something is up at Redoubt. The Alaska Volcano Observatory has put Redoubt on orange alert for aviation and suggest that an eruption could occur with "hours to days". The most recent update from AVO says that a recent overflight of the volcano done this afternoon ...

  • Photos of the activity at Koryak
    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 ...

  • Keeping an eye on Redoubt
    Redoubt Volcano, in Alaska, is one of the more troublesome volcanoes in the state. Not only is it relatively close to population centers, but it also lies directly within the aircraft corridors above the Aleutians for planes headed to Asia and beyond. This means that USGS and AVO geologists have to be especially vigilant in ...

  • Continuing eruptions at Shiveluch
    One of Kamchatka's most active volcanoes is continuing to erupt. Shiveluch, in the northern part of the Kamchatka Peninsula in Russia, produced a 26,000 foot (~8,000 meter) ash column today (November 6) as the eruptions that started in 2006 persist. The reports suggest little danger to people living on the peninsula, however the ash column ...

  • Klyuchevskoy's new eruption
    Reports from Russia indicate that Klyuchevskoy, Russia's largest volcano, is erupting. It sounds like it might not be just a murmur as Alexei Ozerov from the Institute of Volcanology and Seismology of the Far Eastern branch of the Russian Academy of Sciences says the volcano is spewing ash, rock and gases. No real details on how tall the ...

  • Kasatochi erupts
    Just a quick update if you haven't been following the discussion: Kasatochi volcano in the Aleutians is now listed in "Red Alert" as it is erupting (see image above). Not many details beyond the typical description of ash columns, in this case reaching 45,000 feet, which is a pretty decent height. The Coast Guard warns ...

  • Details on the start of the Okmok eruption
    The Okmok Caldera eruption is still going on, almost a month after it started. The latest USGS/SI Weekly Report states:    Strong volcanic tremor on 2 August prompted AVO  to raise the Volcano Alert Level to Warning and the Aviation Color Code to Red. Cloudy conditions prevented satellite observations. Later that day, AVO geologists in the area reported that ...

  • Okmok back to Orange Alert
    After raising the alert level at Okmok Caldera in Alaska to Red over the weekend, AVO has reduced it to Orange. Reports have the volcano producing ash columns of less than 20,000 feet versus the 35,000+ foot columns earlier in the weekend. At the same time, Cleveland Volcano is continuing to issue ash from the ...

  • Weekend update: Llaima, Chaiten, Okmok and Soufriere Hills
    There haven't been any major developments volcano-wise over the weekend, just a few updates on some current rumblings: Soufriere Hills (Montserrat) coughed up more ash, producing ash columns to "thousands of feet" according to reports from the MVO. The eruptions/explosions were centered at the lava dome on the summit of the volcano, Seismicity has also increased, suggesting that ...

  • Cleveland Volcano erupts in the Aleutians & Okmok Update
    Just when you thought it was exciting enough in the Aleutians, word comes in that Cleveland Volcano is erupting as well. Cleveland is a very noisy volcano on Chuginadak Island, having last erupted in February (although it hasn't been updated on the GVP page). Aircraft have been warned about both eruptions in the Alaskan island chain. ...

  • Chaiten ash still causing problems
    It has been a while since we've seen a Chaiten update, but today there is a report that LanChile has had to cancel flights to Puerto Montt due to ash from the volcano. Chaiten has been erupting since early May, so now we're almost 2 1/2 months into the eruption - quite a feat for ...

  • Okmok Eruption 2008
    I'm back from my conference and will hopefully be getting back to a regular schedule!  In the meantime, the biggest news is still the eruption of Okmok Caldera in Alaska. The latest news has the eruption still going strong and the USGS predicting it will continues for potentially weeks to months. The eruption is apparently from ...

  • Photo of the 2008 Okmok eruption
    Here's a stunning shot of the current eruption at Okmok Caldera in Alaska (brought to us by National Geographic). Personally, I think the best part is the fact that this was shot by an Alaska Airlines pilot! Talk about "to the right of the plane..." fodder.
