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).

Looks like a lot of you have found my (fairly new) Eruptions blog via the kind post over on another excellent volcano blog, the aptly titled Volcanism Blog. That blog […]
People living around Semeru Volcano, Indonesia, have been put on alert for a potential eruption. Indonesia’s Centre for Volcanology and Geological Hazard Mitigation has put the volcano on level 3 […]
nn Tungurahua, one of the most active (and harder to pronounce) volcanoes in the Andes, has been experiencing explosions over the last few days. Not much in the report beyond […]
I think we know who wins this battle. At Ruapehu (New Zealand), it isn’t really the lava that is the problem, but the lahars produced by mixing snow, crater lake […]
I’ve made it back from my trip to Washington DC. The Smithsonian Institution is quite a fun place to visit, especially if rocks are your ilk. Be sure to check […]
Everyone loves a “supervolcano”*. According to a recent report, Los Angeles will be erupting from underneath Yellowstone Caldera (Wyoming). OK, not really, but apparently there has been 7 cm of […]
nn It has been rather quiet on the volcano news front over the weekend. A couple tidbits: nn – There are some new data showing the sulfur dioxide flux from […]
The latest eruption at Kilauea has increased the amount of vog on the big island of Hawai’i. Vog is more or less the same as the anthropogenic “smog” produced by […]
nn Happy 28th anniversary of the 1980 Mt. Saint Helens eruption. The volcano had a catastrophic collapse of one side of the edifice that triggered the climatic eruption. Enjoy this clip from […]
If Chaiten, Llaima and Puyehue weren’t enough, the Chilean Regional Emergency Office is placing seismometers on Peteroa volcano after its shown signs of increasing activity. The volcano is located out […]
nn To keep us up to date on the goings-on at Chaiten in southern Chile, well, the volcano is still erupting! Yes, two weeks in and heavy ash is still […]
At first it seemed like the new eruptions at Mt. Etna (Italy) were petering out rather quickly. Instead, now it seems that there are fears that a new rift might […]
Here is a gallery of some ridiculously cool photos from the Chaiten eruption … nn
nn While I was looking at the gallery of Chaiten photos, I noticed another headline (in spanish) saying that the SERNAGEOMIN has issued a yellow alert for potential activity at Puyehue. […]
I just read a report that the ash column at Chaiten is beginning to collapse. The SERNAGEOMIN says that the ash column is only 4.5 km tall now, as opposed […]
nnA bit busy today, so to borrow from the newest USGS/SI Volcanism Report:n On 12 May, the plume rose to an altitude of 8 km (26,200 ft) a.s.l.nDuring an overflight […]
nn Looks like we should expect an eruption at Ruapehu (New Zealand) any time now. Tremors are ongoing, along with increased volcanic gas emissions (specifically SO2 here) and warmer temperatures […]
nn I’ve been trying to keep up with the Chaiten eruption in Chile, but the news is just beginning to sound like a broken record: eruption continues, ash falls, don’t […]
Etna, one of Italy’s (and the world’s) most active volcanoes, has started erupting again. Saturday night the volcano erupted lava flows, although that is pretty much all the details in […]
nn Before we get too far, I wanted to make sure that folks understand that I’m just making educated conjectures on the nature of the eruptions I read about and […]
