Volcanologist, Denison University

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).

It is clear now that the earthquakes occurring in western Saudi Arabia are centered under the Harrat Lunayyir lava field. The question is now: coincidence or concern?
Conflicting reports are floating around about the earthquakes in Saudi Arabia, some claiming that cracks have formed in the land near Al-Ais and smoke has been seen coming from them. However, this is not confirmed - but things continue to shake.
NASA released a stunning image of Mauna Kea taken by astronauts on the ISS.
The mysterious Saudi Arabian earthquake swarm continues. Eruptions readers in Saudi Arabia have provided some on-the-ground updates, but the source of the seismicity is still unclear. Check back for the latest updates!
It has been 29 years since the eruption at Mt. Saint Helens in Washington - an eruption that not only captivated the nation, but helped modernize volcano monitoring in the U.S.
You can never be too prepared with a volcano is located less than 20 km from a city of one million.
So far, you've submitted some great volcano images. Keep them coming!
Bits of volcanic news, including a great image of the eruption at Shiveluch, evacuations related to the earthquakes in Saudi Arabia and the hazards of lake overturn (oh yes, and indie rock).
Saudi officials are attributing magma movement at shallow depths for the recent earthquake swarm in the western part of the country. Are we seeing the beginnings of the first volcanic eruption in Saudi Arabia since 1810? UPDATED
The latest news of global volcanism, including new dome growth at Nevado del Huila
Volcanoes are lining up to be the next to have a large eruption according to scientists monitoring the volcanoes. Which one will it be?
Five years after the eruption of Manam, the former inhabitants of the island in Papau New Guinea are still facing hazards, but these have nothing to do with the volcano itself.
Vote for the next in the Eruptions Volcano Profile series!
A veritable treasure trove of volcanic tidbits, including new undersea eruptions discovered, the end of the eruption in the Galapagos, more Aleutian noise, an excellent interactive of Indonesian volcanism and boarding down an active volcanism (a.k.a., thinning the gene pool).

Sounds like activity at Anak Krakatau is beginning to heat up as the PVMBG in Indonesia raises the alert level.
Deconvolving the tectonic from volcanic signal of earthquakes can be problematic, especially in area where earthquakes of both kinds are common.
There are no eye witness reports from the ground yet, but satellite images suggest an eruption may be occurring at Nyiragongo in the Congo, one of the potentially most dangerous volcanoes in the world.
