Mt. Hood in Oregon, taken August 2008. Image by Erik Klemetti. Click on the image to see a larger version. Quick news! I’m not going to go into too much depth right now about the recent study published in Nature Geoscience on Mt. Hood in Oregon – I plan to talk about it more in…

Lava flows from Kilauea in Hawai`i move towards a home in Kalapana. Whenever I think about the hazards posed by most lava flows, I tend to think about the opening scene in the Hitchhiker’s Guide to the Galaxy. Developers are planning to knock our hero Arthur Dent’s house down and as a last ditch effort…

Some news over the last few days: The lava flows from Kilauea are moving with a vengeance right now, damaging roads and heading for some structures. The lava flows near Kalapana have moved almost 200 meters since Sunday,…

A few very quick hits: Ever-looming Mt. Rainier, with Tacoma, Washington in the foreground. PHIVOLCS is pondering whether to lower the Alert Status at Taal back to Level 1. The volcano has been on Alert Level 2 for the past month after increasing signs of potential eruptive activity. However, seismicity is down at Taal, so…

The Philippine government is upping its concern about an eruption at Taal – and cracking down on tourists and resorts trying to get near Volcano Island in the volcano’s caldera lake. Tourists are only allowed to take boat tours in the lake that go halfway to the…

Playing the waiting game at Taal

A partially-eroded scoria cone in the Taal volcano caldera. As I mentioned earlier this week, PHIVOLCS has raised the Alert Status at Taal in the Philippines to 2 (out of 5) after increasing tremors and gas emissions from the volcano’s crater lakes. Now, the Philippine government is taking this threat very serious, sending divers, helicopters,…

The steaming vent area at Taal in the Philippines in September 1965, when the volcano produced a VEI 4 eruption. The Philippine Institute of Volcanology and Seismology (PHIVOLCS) has raised the alert status at Taal to Level 2 (of 4) and officials in the Philippines are getting ready if the volcano does come back to…

Guatemala’s Santa Maria volcano with the dome complex visible in the foreground. I got a tip the other day from an Eruptions reader of something afoot at Guatemala’s Santiaguito – a part of the larger Santa Maria volcano – and sure enough, there are reports today that the volcano is experiencing an “unusual and violent”…
