Every four years, the volcanological community gets together somewhere in the world to spend a week (or two) talking about…you guessed it, volcanoes. And because volcanology – like any ‘disaster science’ – occupies a special intersection of geologic processes and human impacts, there is an inherent social science aspect in its practice.

Berastagi, a city in northern Sumatra, is a great place for volcanoes, because it has two active ones: Mount Sibayak and Mount Sinabung. Active takes on a different context here; to the locals, Sinabung is active, and dangerous, while Sibayak, which hasn’t erupted in living memory, is not.

Visiting one of the largest volcanic lakes (and calderas) in the world in northern Sumatra: Toba Caldera

Remember a couple of months ago when Google Earth Timelapse got updated? I didn’t spend a lot of time looking at it back then, but I’ve taken it for a spin since then and – being a volcanologist – decided to look at volcanoes. And it turned out to be a lot of fun.

When you bring together volcanoes and ice – as many places in Iceland do – you get floods. Specifically, they’re called jökulhlaups, which literally means “glacier run” but in reality means a glacial outburst flood. Originally the term was used for subglacial outburst floods from Vatnajökull ice cap, which covers the Grímsvötn and Öræfajökull volcanoes, but it’s come to mean any large, abrupt release of water from under a glacier or from a lake at the glacier front.

If you’re a volcanologist – or really any geology buff who appreciates volcanoes – Iceland is flat-out paradise.

Flying from the West Coast to Iceland doesn’t leave you a lot of time for sleeping, and neither does the prospect of standing on the on-land expression of a mid-ocean rift.

I was fortunate enough to spend several weeks in Yellowstone National Park this summer, doing geophysical surveys in hydrothermal areas. I’ll be talking about those elsewhere in a few weeks (keep an eye on the AGU Instagram!), but in the meantime I wanted to show off some of the other excellent features of the park. Fieldwork in Yellowstone – and especially fieldwork with electrical equipment – is at the mercy of …

I’m in the midst of preparing for field work, and it got me to thinking about the public perception of how geologists do research. A lot of us probably extol our chosen profession because of the opportunity for working outside of an office – I know it’s one of the reasons I often bring up when I’m asked why I love volcanology. But I also find that when people follow …

It’s not very often that I comment on news articles, but a reader of the blog recently brought this one to my attention, and it hits close to home. The article is in the Washington Post’s Travel section and is entitled, “In Guatemala, a treacherous hike to one of the world’s most active volcanoes”. That title pretty much covers why I’m so upset – and conflicted – about the author of the piece is writing about.
