Yet another new eruption for 2010! Turrialba volcano in Costa Rica in an undated photo. Turrialba in Costa Rica erupted today, prompting the evacuation of tens of people from the region near the volcano. The eruption appears to be relatively small, producing ash and some pyroclastic material. The area around the volcano is not very…

A pile of news for the new week! The glow of new lava flows from Nyamuragira in the Congo, taken from the Virunga Park Headquarters, January 2, 2010. Mayon PHIVOLCS may lower the alert status at Mayon to Level 2 after almost a week of lower seismicity and no ash explosions since December 29th. Schools…

Finals day for me, so I’ll be grading grading grading … but first, a little news: The May 2009 eruption of West Mata. Image courtesy of NSF and NOAA. I covered it in May, but the popular press is now all over the West Mata undersea eruption – mostly thanks to the media boost that…

A while back I reported on a brief eruption at Piton de la Fournaise on Reunion Island and now a number of Eruptions readers have pointed out to me that it has erupted again (french).…

If you ever wonder what might happen to the U.S. if a large volcanic eruption, lets say from Rainier or Long Valley or Shasta, occurred, you can look at the island of Montserrat for some of the potentials problems.…

I’ll be giving a talk this afternoon here at Denison on rhyolite generation, so I might be a little brief this morning. Undated image of Mayon in the Philippines. The province of Albay in the Philippines is on alert for both a typhoon and a volcano (that country seems to be hit with that

The game of insurance is everywhere in the news these days so it isn’t too surprising to run across this brief article about the perils of getting insured if you live on an…

Volcano Profile: Mt. Erebus

The next up in my Volcano Profiles Series, is one of the most remote volcanoes on the planet, yet also one of the more closely studied and monitored (albeit from afar). Joining Vesuvius, Hood and Rabaul is Mt. Erebus, an active volcano on Ross Island in Antarctica and it definitely has some unique features. VOLCANO…

Hydrothermal fields are tricky beasts. They can wax and wane as the magmatic system heats and cools, as the water table rises and falls and as other events such as earthquakes or explosions might change the conduit systems. Changes are relatively common, as we’ve seen in recent events in the Yellowstone Basin and with the…

A quick update on the rockfall in the Halema`uma`u (got it right this time!) Crater at Kilauea. Last week a rockfall blocked the vent that had been glowing for most of the year from the lava below, but the debris clogged the vent, producing minor accidental tephra explosion. Lava in the recently “clogged” Halema`uma`u vent…
