GVP Weekly Volcanic Activity Report for November 17-23, 2010: Semeru, Tungurahua and more
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).

Quick note as I almost forgot to post last week's Smithsonian/USGS Global Volcanism Program's Weekly Volcanic Activity Report. Busy week all around for volcanoes - we've seen activity at Bromo, Merapi, Anak Krakatau, Bulusan, Kilauea and more ...
Some highlights include:
Semeru: Another Indonesia volcano made some noise, with Semeru producing a ~4.3 km / 14,000 feet plume and the sulfur dioxide plume was detectable as far as 75 km SW from the volcano. Semeru joins its neighbor Bromo (Tengger Caldera) along with Rinjani, Merapi, Anak Kratakau and Batur in the Report.
Tungurahua: I haven't had a chance to mention much about the new eruptions at the Ecuadoran volcano, but Tungurahua has been producing a steady ash plume for the past few weeks. Over the last few days, the plume has been consistently over 7 km / 20,000 feet and the ash has been causing problems in Ecuador (spanish), especially around Guayaquil to the southwest (spanish).
Guatemala: Both Fuego and Santa Maria in Guatemala made the report as well, with small explosions typified by short (< 1 km) ash plumes and frequent incandescent blocks. Ash fall was noticed as far at 8 km from Fuego.

Science and the squishiness of the human mind. The joys of wearing whatever the hell you want, and so much more.
- Why can't we have a human-sized cat tree?
- What would happen if you got a spoonful of a neutron star?
- Why do we insist on dividing our wonderfully complex selves into boring little boxes
Progressive America would be half as big, but twice as populated as its conservative twin.
- America's two political tribes have consolidated into 'red' and 'blue' nations, with seemingly irreconcilable differences.
- Perhaps the best way to stop the infighting is to go for a divorce and give the two nations a country each
- Based on the UN's partition plan for Israel/Palestine, this proposal provides territorial contiguity and sea access to both 'red' and 'blue' America
A guide to making difficult conversations possible—and peaceful—in an increasingly polarized nation.
- How can we reach out to people on the other side of the divide? Get to know the other person as a human being before you get to know them as a set of tribal political beliefs, says Sarah Ruger. Don't launch straight into the difficult topics—connect on a more basic level first.
- To bond, use icebreakers backed by neuroscience and psychology: Share a meal, watch some comedy, see awe-inspiring art, go on a tough hike together—sharing tribulation helps break down some of the mental barriers we have between us. Then, get down to talking, putting your humanity before your ideology.
