GVP Weekly Volcanic Activity Report for August 3-9, 2011: Cleveland's dome, Indonesian volcanoes and a busy Etna
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.
I'm back in Ohio and will be for the foreseeable future ... less than 3 weeks until classes start again here at Denison. Lots of things to get organized for me over the next few weeks.
Today, I thought I'd just quickly post on the latest Global Volcanism Program Weekly Volcanic Activity Report - thanks, as always, to the Smithsonian Institute, the USGS and Sally Kuhn Sennert.
Alaska: There has been some information in the news about the activity at the remote Alaskan volcano, Cleveland, and all of it seems to suggest a new dome at the summit. The USGS did have a Gulfstream III overfly the volcano to image the new dome via radar, but the results of this won't be released for at least a few days. So far, the dome growth has not been accompanied by any significant explosive activity - a bit of a surprise at Cleveland.
Indonesia: The island nation is seeing its fair share of activity lately, and now Karangetang has come back into the fray. The volcano has experienced some small explosions over the last week that has caused villagers to flee. We also still have some activity at Lokon-Empung and Krakatau.
Italy: Last night, Dr. Boris Behncke mentioned that we might be heading towards a 10th eruptive event of the year at Etna - be sure to watch the webcams closely today. It definitely has been a busy summer at Etna and Stromboli. Check out some of Dr. Behncke's images from a recent trip to Stromboli as well.

We're more dependent on them than we realize.
- Scientists says our survival depends on biodiversity.
- A natural climate strategy we often forget.
- Seeing our place among the Earth's living creatures.
There's a high social cost that comes with lighting up.
While short-term results are positive, there is mounting evidence against staying in ketosis for too long.
- Recent studies showed volunteers lost equal or more weight on high-carb, calorie-restricted diets than low-carb, calorie restricted diets.
- There might be positive benefits to short-term usage of a ketogenic diet.
- One dietician warns that the ketogenic diet could put diabetics at risk for diabetic ketoacidosis.
