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.

After raising the alert level at Okmok Caldera in Alaska to Red over the weekend, AVO has reduced it to Orange. Reports have the volcano producing ash columns of less […]
nn There haven’t been any major developments volcano-wise over the weekend, just a few updates on some current rumblings: nn n n Soufriere Hills (Montserrat) coughed up more ash, producing ash columns to […]
nn The Alaska Volcano Observatory is reporting that both current eruptions in the Aleutians – at Okmok Caldera and Mount Cleveland – are showing signs of a lava extruding from […]
nn ONEMI, the Emergency Office of Chile, is expressing concerns that Chaiten might be readying an even bigger blast than what we’ve seen already in the past few months. In […]
I am beginning to feel like a broken record, but the latest reports from Chile indicate that the ongoing eruption at Chaiten is ramping back up again, almost 3 months […]
Admittedly, this is only a brief report, but there are indications that Tungurahua in Ecuador might be heading into a new period of heightened activity. Over the last week or […]
There were a number of small explosive events at Soufriere Hills in Montserrat in the past few days. Small ash columns of ~5,000 feet were produced, likely caused by some […]
nn Just when you thought it was exciting enough in the Aleutians, word comes in that Cleveland Volcano is erupting as well. Cleveland is a very noisy volcano on Chuginadak Island, […]
The latest eruption at Llaima is beginning to slow down according to Chilean state geologist, Hugo Moreno. The volcano has been erupting for most of the month, forcing limited evacuations. […]
I suppose this is more “unnews” than “news”, but workers at Ruapehu in New Zealand report that seismicity has decreased, gas emissions have returned to background and the crater lake […]
It is always fun to try to comprehend the sorts of numbers that geological processes produce. I mean, how much is 125 million cubic yard exactly? Well, the Cascades Volcano […]
nn I’m back from my conference and will hopefully be getting back to a regular schedule!  nn In the meantime, the biggest news is still the eruption of Okmok Caldera […]
It has been a while since we’ve seen a Chaiten update, but today there is a report that LanChile has had to cancel flights to Puerto Montt due to ash […]
Here’s a stunning shot of the current eruption at Okmok Caldera in Alaska (brought to us by National Geographic). Personally, I think the best part is the fact that this […]
Not really a “new eruption” as such, but the Geophysics Institute of Ecuador is reporting that Tungurahua, one of the most active volcanoes in South America, has been erupting ash […]
nn Sorry about the delay with updates, I am actually at a meeting filled with volcanologists (of all things), so updates might be a little sporadic. nnA lot of news […]
Sorry about the brevity of this update, but I’m exhausted. From the Alaska Volcano Observatory (AVO): At this time, based on AVO analysis of satellite data, ash is continuing to […]
nn Okmok Caldera in Alaska’s Aleutian Islands erupted today, sending an ash column to at least 30,000 feet. Very little news has been released about the eruption so far beyond […]
Some news of a series of small eruptions at San Cristobal in Nicaragua. Ash from the small explosions drifted to a town near the volcano, however officials for Ineter in […]
Just a brief note that the USGS has officially pronounced the eruption that started in 2004 at Mt. Saint Helens over. They lowered the alert level to “normal” after months […]
