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).

The Japanese Coast Guard caught on film Fukutoku-Okanoba, an submarine volcano off Minami Iwo, erupting yesterday.
What is the structure of a caldera ... and if Yellowstone's magma was making its way to the surface, what might we expect to see as harbingers of eruption?
Sure enough, the last 2 days of earthquakes at Yellowstone seem to be getting shallower - but do we see any other changes in the caldera? UPDATE: now with error bars!
A news report from Pakistan suggests a volcano just erupted in that country - which is quite a surprise. UPDATED: huh?
Time for another Eruptions mailbag - send me your questions!
As activity increases at Ecuador's Tungurahua, the question of evacuations comes into the spotlight.
Yellowstone makes it to the New York Times, Costa Rica defines some hazard zones around the reawakened Turrialba and how to vacation near a volcano.
The swarm marches on ... but the pattern seems to show that the earthquakes are pretty much staying put around 10-11 km depth.
A pile of news to end your week, including new lightning that comes from volcanoes, ash fall across Ecuador, a new USGS/SI Volcano Report and storing your excess carbon dioxide in ancient lava flows.
Officials in Russia have decided to stop funding KVERT - the body that monitors and responds to volcanic eruptions in eastern Russia. This is bad news.
So why is the current earthquake swarm at Yellowstone not likely to lead to an eruption? Well, mostly because we've had so many other swarms that don't lead to eruption, and this one shows no signs of it being any different.
As the earthquakes keep coming, Yellowstone keeps everyone's attention. Meanwhile, Turrialba in Costa Rica is prompting more evacuations. UPDATED And now Turrialba has a webcam!
Two earthquake swarms have gotten people's attention - the Yellowstone swarm seems to be dying down, but the swarm at Obsidian Butte in California is still going strong.
Two of Japan's most active volcanoes get the spotlight shone of them - with some spectacular images as proof.
The latest volcano news from around the world - including activity at Kharimkotan in Russia and Planchon-Peteroa in Chile.
The earthquakes at Yellowstone roll on, a river of lava is captured on video at Kilauea and a hazard map for Gran Canaria is released.
More details on the current earthquake swarm at Yellowstone along with a reader-made video showing the seismicity of the swarm.
There's been an earthquake swarm in Yellowstone over the last few days - nothing out of the ordinary, but always exciting nevertheless.
Lava filling the Halema`uma`u Crater! Inflation in the caldera! Increased sulfur dioxide emissions! Kilauea looks like its ramping up for something ...
Updates on the last week's volcanic events from around the world.
