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).

A quick note (as I’m buried in zircon): The Alaska Volcano Observatory has installed a webcam at Redoubt to monitor for an eruption. It is a little cloudy today (not […]
I’m just toying with the new WordPress Poll option, so I thought I’d throw this out at Eruptions readers. Enjoy! Feel free to leave comments justifying your pick. nn
Eruptions reader Ross was very right in pointing out that something is up at Redoubt. The Alaska Volcano Observatory has put Redoubt on orange alert for aviation and suggest that […]
I wouldn’t normally use this blog for something like this, but google has failed me. When I was in New Zealand, I saw a video on the 1995-96 eruptions at […]
Nevado del Huila continues to cause problems in Colombia. Over 4,000 people had to be evacuated today from the Belalcazar area after the volcano showed new signs of eruption. No […]
nn I made it back from New Zealand yesterday after spending the last two weeks looking at some of the most remarkable volcanic landscapes you could imagine. I’ll add more […]
nn Right as Yellowstone is getting interesting (or at least had signs of interest), Eruptions is going on a bit of a break again starting January 2. This time it is […]
nn Some more information is coming out about the activity at Koryak (aka Koryaksky) in Kamchatka. Russian geologist Alexei Ozerov says that the activity at Koryak (note: the image in the article […]
nn Well, the holidays (and its visitors) have derailed my blogging ability, so in that note, I will officially declare the Eruptions holiday until 12/30. Merry Christmas (or whatever you celebrate) […]
Today was a lot of talking and posters. Talking mostly about all things concerning Taupo and Okataina volcanism in New Zealand. Posters ran the spectrum from learning some nifty new […]
I don’t know if the live-blogging AGU will work out, but we’ll see. However, I did find out today that Chaiten was a compositionally zoned eruption. Good times!
nnThe latest eruption of Sourfriere was captured from space, and NASA has just released the MODIS picture of the volcano in action. The image (above and linked) was taken 2 […]
