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…

2009: The Volcanic Year in Review

Here it is, my attempt to recap a year’s worth of volcanic events. By no means is this supposed to capture every event, but rather the highlight/lowlights and what most captivated me during 2009. I’ll be announcing the winner of the 2009 Pliny for Volcanic Event of the Year tomorrow. Waimangu Geothermal Valley in New…

The southern Washington (and northern Oregon) Cascades, with Hood (foreground), St. Helens and Adams (middle) and Rainier (background).

These volcanoes are defined by IAVCEI – the International Association of Volcanology and the Chemistry of the Earth’s…

FEMA and volcanoes

So, as I am apt to do from time to time, I was wandering the interweb and stumbled across the FEMA (Federal Emergency Management Agency) for Kids website. Naturally, I thought, what do they have to say about, oh, I don’t know, volcanoes. Well, was I in for a doozy! FEMA, in its infinite wisdom,…

All quiet on the Cascade front

The only volcanic arc in the lower 48 states continues to be pretty darn quiet according to the USGS. The Cascade range that spans from Lassen Peak in the south to Mt. Baker in the north (and maybe Mt. Garibaldi in Canada) has been remarkably quiet in terms of eruptions for the last century. In fact,…
