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 eruption in Iceland roars onward, introducing the Volcano Picture of the Week and Kilauea lava flows take a wrong turn.
The Eyjafjallajökull eruption has become more explosive over the last day, prompting new closures of airspace over Ireland and the UK.
The ash from the Eyjafjallajökull eruption is prompting new airspace closures over Ireland for Tuesday.
NOVA's new Mt. Saint Helens special has some great footage of the volcano, but plays a little loose with the science and doomsday tone.
The eruption at Eyjafjallajökull is now producing lava flows that are slowly working their way downslope as well as the strombolian summit explosions.
If you can believe it, the Chaiten eruption - and this blog - have just turned two!
Have any memories of the May 1980 Mt. Saint Helens eruption? Send them in for Eruptions 30th anniversary commemoration.
The Iceland eruptions continues producing ash and lava flows, Kilauea's east rift looks to be tapering off, videos of eruptions at Colima in Mexico and the latest USGS/SI report.
Is Ischia a bigger threat than Vesuvius, EU starts to pay back the ash-stricken airlines, tourists get too close to Santiaguito and the eruption at Gaua continues.
A series of "usual and violent" explosions at Guatemala's Santiaguito dome has prompted authorities to raise the alert level to the second highest level.
As the Eyjafjallajökull eruption continues, the political firestorm that has follows has me asking the naysayers would you have let your mother fly if the sky was potentially full of hazardous ash?
I'll get to your emails ... really!
The fallout of the Eyjafjallajökull eruption will likely be far reaching, from the politics of the EU, to climate research, to the future of air travel.
In an eruption without a single fatality and some of the best response by officials to the eruption, some people are calling for "blame" to be doled out.
Eyjafjallajökull seems to be settling into a pattern of small explosions as European airspace reopens - and see a day's worth of eruption in less than two minutes!
News on the current situation at Gaua in Vanuatu, continuing rumblings in Costa Rica and Russia and more stories of ash, this time from South America.
European airspace begins to reopen as the eruptions at Eyjafjallajökull settle down for the time being.
There are signs that the style of volcanism at Eyjafjallajökull has changed. Meanwhile, ash from the eruption continues to cause problems and has reached eastern North America.
European airlines took test flights over Europe today to see the effect of the Eyjafjallajökull ash on their jets - but it is still unclear when flights over Europe will return to normal.
Could increased volcanism and deglaciation be linked? It is hard to tell, but fascinating to ponder.
