Okmok Update

Sorry about the delay with updates, I am actually at a meeting filled with volcanologists (of all things), so updates might be a little sporadic. A lot of news today about Okmok erupting in the Aleutians. The Alaska Volcano Observatory had this to say: The eruption at Okmok continues based on high levels of seismicity and…

Okmok Caldera in Alaska’s Aleutian Islands erupted today, sending an ash column to at least 30,000 feet. Very little news has been released about the eruption so far beyond this information about the eruption column and some bits about precursor seismicity. A number of flights to Unalaska Island were cancelled due to the eruption. I’ll…

Rumblings at San Cristobal

Some news of a series of small eruptions at San Cristobal in Nicaragua. Ash from the small explosions drifted to a town near the volcano, however officials for Ineter in Nicaragua say that there is little chance of a large eruption. San Cristobal is one of the seven active volcanoes in Nicaragua. It has a…

Thus endth the eruption

Just a brief note that the USGS has officially pronounced the eruption that started in 2004 at Mt. Saint Helens over. They lowered the alert level to “normal” after months with little to no signs of activity. The new dome that grew in the crater formed by the 1980 eruption is 125 million cubic yards…

Llaima (Chile) is experiencing an increased tempo in its current eruption. The National Emergency Office in Chile is reporting that the eruption has begun to take a more explosive character, with pyroclastic material being shot hundreds of meters from the main vent. Although the officials have not changed the current status of the evacuation, which…

Kilauea’s new fire fountain

  Kilauea is busy keeping geologists and tourists alike wondering what the volcano will be doing next. The current report on the volcano tells of a new fire fountain at the Thanksgiving Eve Break-out “rootless cone”, about 6 miles from the ocean. The fire fountain started on Sunday night, issuing lava up to 40 feet in…

There are some nice videos of the current eruption of Kilauea (after some tedious commercials via the link at the top of the article) with lava spattering and lava reaching the sea on the 4th of July. Not much description of the eruption in the article, but it sounds like it is just the Hawai’ian…

Anak Krakatau at highest alert

Indonesia’s Volcanology and Geological Disaster Mitigation Center of the Ministry of Energy and Mineral Resources (whew, that is a mouthful) has placed Anak Krakatau on high alert for increased activity. Tourists were warned not to climb on the volcanic island in the Sunda Straits that rises from the remnants of the famous 1883 eruption of Krakatau.…

The current eruption at Llaima in Chile is causing some concern about flooding in the Rio Calbuco near the volcano. The lava flows are melting snow on the volcano and this is being exacerbated by heavy rain in the area as well. The eruption seems to have waned some according to the governor of the…

Chaiten eruption photos

There are some astounding new pictures of Chaiten in full eruption over at the Smithsonian Website. There pictures were released by the USGS/VDAP team and show a full eruption column coming from the new dome in the Chaiten caldera (see above and below). The dome itself looks giant, filling up a lot of the old…
