GVP Weekly Volcanic Activity Report for September 29-October 5, 2010
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).

Colombia It was a busy week, volcanically-speaking, in the South American nation. We're talked about Nevado del Ruiz and the GVP mentions that the volcano has also shown changes in "deformation and geochemistry", which for the latter I assume means from the gases being released (but it could be water as well). Over at Nevado del Huila, the active summit dome produced plumes that reached up to 7.5 km / 25,000 feet along with incandescence and hot rock falls as part of a partial dome collapse (spanish).
Chile Planchon-Peteroa continues to produce ash plumes that reach as high as 3-6 km / 10-20,000 feet. Changing winds have raised considered of ash fall (spanish) in communities near the volcano, but ONEMI says there is no real danger (spanish). The volcano remains on Yellow Status - you can check out the latest SERNAGEOMIN report here (spanish - follow Region del Maule - Reportes - 2010)
Guatemala Fuego continues to experience explosions - and even an occasional lahar. This continues the pattern from earlier this summer. Pacaya also produced weak steam plumes as part of its continuing activity.
Kuril Islands It has been a while since we talked about Sarychev Peak - a big newsmaker in 2009 - but the volcano does continue to be active. Ash plumes were detected from the island volcano by satellite. Currently, remote sensing by satellite is the only monitoring for the remote volcano, which lacks any seismic monitoring.

The controversy around the Torah codes gets a new life.
- Mathematicians claim to see a predictive pattern in the ancient Torah texts.
- The code is revealed by a method found with special computer software.
- Some events described by reading the code took place after the code was written.
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
Orangutans join humans and bees in a very exclusive club
- Orangutan mothers wait to sound a danger alarm to avoid tipping off predators to their location
- It took a couple of researchers crawling around the Sumatran jungle to discover the phenomenon
- This ability may come from a common ancestor
