Erik Klemetti

Volcanologist, Denison University

I write the Eruptions blog on Big Think.  I've been mesmerized with volcanoes (and geology) all my life. It helps that part of my family comes from the shadow of Nevado del Ruiz in Colombia, where I could see first hand the deadly effects of volcanic eruptions. Since then, I've taken a bit of a winding path to become a volcanologist. I started as a history major at Williams College, almost went into radio, but ended up migrating to geology, including an undergraduate thesis on Vinalhaven Island, Maine. I followed this up by changing coast to get my Ph.D. from Oregon State University. Then I ran a MC-ICP-MS lab at University of Washington for a spell (and wrote for an indie rock website). I spent three years as a postdoctoral scholar at University of California - Davis studying the inner workings of magmatic systems. I am now an assistant professor at Denison University and have projects in New Zealand, Chile and Oregon.

I am fascinated by volcanoes, their eruptions and how those eruptions interact with the people who live around the volcanoes. I started this blog after getting frustrated with the news reports of volcanic eruptions. Most of them get the information wrong and/or are just sensationalistic. I will try to summarize eruptions as they occur, translate some of the volcanic processes that are happening and comment on the reports themselves.

And no matter what people tell you, I definitely do not have a cat named Tephra. (OK, I do).

Just to keep us appraised of the situation at ever-steaming-and-shaking Redoubt: nnFrom AVO (2/6/2009 11:05 AM)n Unrest at Redoubt Volcano continues. nAfter the tremor episodes of yesterday, seismic activity has remained […]
For all you Redoubt vigil holders… According to AVO at ~12:30 (2/5/09): Starting at 11:18 AKST (20:18 UTC), a burst of more intense seismic tremor occurred. This episode lasted for […]
nn Bored with waiting for Redoubt to erupt? Well, Nevado del Huila in Colombia looks like it is also on the eruption watch list. A fly-over of Huila performed by […]
