Eruptions prompt new evacuations at Tungurahua
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).

I mentioned earlier today that I was hoping that nothing big happened over the weekend because of all the grading I needed to do. Well, it looks like I need to reacquaint myself with Murphy and swallow my words.
Ecuadoran officials have called for evacuations of the slopes of Tungurahua after the volcano increased its ash emissions and explosions, including the production of some pyroclastic flows (spanish). Eruptions readers have sent images that show the thermal bloom above the volcano and the Washington VAAC has issued an alert to FL260 (8 km / 26,000 feet). The evacuation around the volcano applies for people living within ~12 km of the volcano and you can see some images of the impressive explosive column coming from the volcano (see top left). The National Risk Ministry has kept the alert at Red near Tungurahua (spanish). In 1999, over 15,000 people had to be evacuated when the volcano erupted and Tungurahua has been erupting frequently since it began a new period of activity over 11 years ago.

Scientists have developed new ways of understanding how the biological forces of death drive important life processes.
- Researchers have found new ways on how decomposing plants and animals contribute to the life cycle.
- After a freak mass herd death of 300 reindeer, scientists were able to study a wide range of the decomposition processes.
- Promoting the necrobiome research will open up new areas of inquiry and even commerce.
What do we see from watching birds move across the country?
- A total of eight billion birds migrate across the U.S. in the fall.
- The birds who migrate to the tropics fair better than the birds who winter in the U.S.
- Conservationists can arguably use these numbers to encourage the development of better habitats in the U.S., especially if temperatures begin to vary in the south.
Explore how alcohol affects your brain, from the first sip at the bar to life-long drinking habits.
- Alcohol is the world's most popular drug and has been a part of human culture for at least 9,000 years.
- Alcohol's effects on the brain range from temporarily limiting mental activity to sustained brain damage, depending on levels consumed and frequency of use.
- Understanding how alcohol affects your brain can help you determine what drinking habits are best for you.
