Three volcanoes captured from space: Puyehue-Cordón Caulle, Anak Krakatau and Kilauea
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 wanted to point out a series of images posted by the NASA Earth Observatory that capture three volcanoes that are currently restless or outright erupting ... right now! Well, at least within the last few days.
Puyehue-Cordón Caulle: It seems surprising that after 2 months, the volcano in Chile is still going strong, but sure enough, the volcano is still producing a gorgeous ash plume and some lava flows. The ash continues to cause air travel snarls in southern South America along with causing problems for ski area operators in the region. The SERNAGEOMIN posted a report (spanish) on the 2 months of activity at Puyehue-Cordón Caulle and they say that explosive eruption are likely to continue for the time being, just not at the same level of intensity as the beginning of the eruption.
Kilauea: I talked a little bit about the recent activity at Kilauea eariler today, but in this image, you can see the new lava flows from Kilauea along with vapor plume from the Halema`uma`u Crater pit.
Anak Krakatau: Finally, over in Indonesia, we can see some the activity at Anak Krakatau, as this July 31 image captures the wispy plume from the volcano. What really stands out to me on this image are the gorgeous lobate lava flows that are continuing to build the island itself. I'm also impressed by the little stand of vegetation that clings to the volcanic island - shows just how much life can try to persist in the face of almost constant volcanic activity.

Both schizophrenics and people with a common personality type share similar brain patterns.
- A new study shows that people with a common personality type share brain activity with patients diagnosed with schizophrenia.
- The study gives insight into how the brain activity associated with mental illnesses relates to brain activity in healthy individuals.
- This finding not only improves our understanding of how the brain works but may one day be applied to treatments.
It's a development that could one day lead to much better treatments for osteoporosis, joint damage, and bone fractures.
- Scientists have isolated skeletal stem cells in adult and fetal bones for the first time.
- These cells could one day help treat damaged bone and cartilage.
- The team was able to grow skeletal stem cells from cells found within liposuctioned fat.
Gut bacteria play an important role in how you feel and think and how well your body fights off disease. New research shows that exercise can give your gut bacteria a boost.
- Two studies from the University of Illinois show that gut bacteria can be changed by exercise alone.
- Our understanding of how gut bacteria impacts our overall health is an emerging field, and this research sheds light on the many different ways exercise affects your body.
- Exercising to improve your gut bacteria will prevent diseases and encourage brain health.
