Ísland: Floods

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.

Ísland: Volcanoes

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

Ísland: Rifts

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.

Yellowstone hot springs: Upsetting your color scale

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 …

Making the fieldwork count

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 …

Common sense and volcano tourism

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.

Altered states (of lava domes)

Time for some shameless self-promotion – but also some research blogging. Last week I (finally) had a paper come out about my graduate modeling work on the hydrothermal systems and alteration in lava domes. (I’m sorry it’s not open access – I couldn’t afford it this time! But feel free to contact me if you want a copy.) Basically, the rundown is this: Lava domes, like volcanoes in general, are big …

#FieldWorkFails

There’s been a hilarious meme on Twitter the past couple of weeks that follows in the footsteps of #OverlyHonestMethods: #FieldworkFail. If you’ve ever gone out in the field (i.e., not in a lab or office) to do your research, you know that there are many opportunities for things to go wrong. Particularly if you travel to remote locations, work with animals, or rely on finicky equipment to get the job done. (Or, in my case, when you work with volcanoes.) A number of media outlets picked up some of their favorite tweets, and I’m happy to say that two volcanologists made it on many of the lists: myself and Alison Graettinger, who’s a postdoc at the University at Buffalo.

Domes galore: Mono Craters, Long Valley

Being the guest lecturer on a geology trip is great, especially if you get to talk about your favorite geologic features. But what does one do when volcanology day is over and it’s time for the students to do a moraine mapping project? Naturally, sit on a convenient rock and observe some lovely lava domes.

Domes galore: Panum Dome, Long Valley

Oh, man. Summer is a terrible time for keeping up with blog posts, but I’ve had a good reason to be absent – I was off in Denver on business and slightly wilder parts of California with my alma mater’s summer field course. I mean, what geologist could pass up the chance to tag along on a trip to Long Valley and Yosemite? During the Long Valley and Mono Lake portion of the trip, I actually did do a little work, serving as the trip’s volcanology expert and talking about lava domes as much as anyone would let me. Because Long Valley may be a beautiful caldera and the site of one of the world’s largest eruptions, but it also has domes. Boy, does it ever have domes.
