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).

You can find out more about my research by visiting my website. If you have any comments, questions or information, feel free to contact me at eruptionsblog at gmail dot com.

The seemingly constantly restless Tungurahua had a significant explosive eruption, prompting evacuations of schools and villages near the volcano. Tungurahua produced a 7 km / ~23,000 foot ash plume, which […]
Eruptions reader Gitta noted a fairly impressive ash plume at Chile’s Planchón-Peteroa – at least seen on the webcam. The plume isn’t especially tall (see below), at least not from […]
There has been an awful lot of debate about the decision to close the airspace over Europe for days during the beginning of the explosive phase at Eyjafjallajökull last spring. […]
There has been some discussion over the years here on Eruptions about what might happen if you were to bomb an eruption volcano. Now, this might be to divert a […]
It has been a couple weeks since I posted the USGS and Smithsonian Institute’s Global Volcanism Program Weekly Volcanic Activity Report – being busy with work every day for the […]
“You put super in front of eruption and I don’t imagine it makes it better.” – FEMA Sec. Wendy Reiss in Supervolcano. This week in my Freshman Volcanoes class here […]
A brief update today on the activity at Taal in the Philippines. There has not been a significant change in the behavior of the caldera, with the latest PHIVOLCS update […]
Let’s get to some updates on volcanic (or possibly not) rumblings around the world: Philippines: PHIVOLCS are watching Taal closely, but at least over the last 24 hours, seismicity at […]
Activity at the Philippine caldera Taal continues to increase. The latest update on Taal from PHIVOLCS reports 21 earthquakes under the volcano in the 24 hours between April 17-18, meaning […]
Just so you don’t think I’ve fallen off the face of the Earth … I have been at the 2011 Keck Geology Symposium for Undergraduate Research at Union College for […]
It has now been one year since the eruption that closed the skies over Europe and captured the world’s attention. Before April 13-14, 2010, most people outside Iceland (or this […]
First off, a big thank you to James Reynolds who took questions from my Volcanoes class here at Denison today. It was a great chat with the students! Now, we […]
I’ve got a brief update about the activity at Taal in the Philippines to start us off: The news of a potential eruption at Taal continues – and the latest […]
Another quick weekend post! Etna has sprung back to life as April opens, with new eruptions from the Southeast Crater Cone. Friday and Saturday (April 8-9), the Italian volcano produced […]
Very brief update as I spent all day in the Department of Geological Science at Michigan State and gave a talk so, I’m a bit exhausted (but thanks for a […]
If you could pick as close to an anonymous volcano in the Pacific Northwest, you might be tempted to pick Newberry Caldera in Oregon (I might also take partial credit for […]
Yesterday I mentioned the Auckland Volcanic Field – the cluster of volcanoes underneath New Zealand’s largest city. Although the Auckland Volcanic Field is a region to monitor for activity, it […]
I’m as surprised as you are, but it is already Monday. Busy week for me – students getting ready to register for Fall Semester courses and a talk to give […]
Over the last year, we’ve been hearing about unrest at the Taal caldera in the Philippines. Last year, PHIVOLCS even raised the alert status briefly when seismicity at the volcano […]
What's with all the microearthquakes under the eastern seaboard? Are we, as a Dartmouth geologist suggests, seeing a resumption of volcanic activity associated with a newly active subduction zone?
