Wednesday Whatzits: Keeping up with Iceland, Etna and Kilauea from space and Central America's geothermal riches
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).

Good morning from a drizzly Ohio!
Been a rather quiet news for much volcano news so far - well, that is beyond the reawakening of Nevado del Ruiz in Colombia. I haven't found much more information beyond my update yesterday, but I'll keep my eyes and ears open.
A few quick bits to tide us over:
A new Iceland Blog: If you haven't already, be sure to check out Jon Frimann's new blog - the aptly titled Iceland Volcano and Earthquake Blog. He has information on every noise the volcanoes of Iceland make. Talk about packed full of all the details of the inflation/deflation, earthquakes and rumors about any potential volcanism on the North Atlantic island nation. Hopefully Jon will continue to grace us with updates over here on Eruptions as well if big things are brewing in Iceland.
Images of Etna and Kilauea: The NASA Earth Observatory posted a couple new images this week. The first is of Mt. Etna in Italy, showing the steaming plumes on the summit region. Our friend Boris Behncke assisted with the annotating of the image. Not a lot to report on Etna since the explosions earlier this fall, but Boris, as always, has posted great images of the area around the volcano. The second has an image of the ocean entry of lava at Kilauea, which is creating a lava delta. You can see both the satellite and a land-based image of the ocean entry - and be sure to check out the post on the delta by Brian Romans over at Clastic Detritus.
Geothermal energy in Central America: The Freakonomics Blog at the New York Times had a very brief post on geothermal energy in Guatemala - specifically tapping the heat generated at Pacaya.Much of Central America is trying its hand with geothermal energy thanks to the high heat flow under much of the region.

The stories we tell define history. So who gets the mic in America?
- History is written by lions. But it's also recorded by lambs.
- In order to understand American history, we need to look at the events of the past as more prismatic than the narrative given to us in high school textbooks.
- Including different voices can paint a more full and vibrant portrait of America. Which is why more walks of American life can and should be storytellers.
A glass of juice has as much sugar, ounce for ounce, as a full-calorie soda. And those vitamins do almost nothing.
Quick: think back to childhood (if you've reached the scary clown you've gone too far). What did your parents or guardians give you to keep you quiet? If you're anything like most parents, it was juice. But here's the thing: juice is bad for you.
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
