Italy in Geological News

First a volcano-related item: How did the victims of the Plinean Eruption of Vesuvius die – a summary from io9, of an article assessing how the victims of the Vesuvius eruption died. It will come as no surprise to anyone familiar with how freaking scary pyroclastic flows are that they died from being flash-cooked by ...

Happy Anniversary, Mount St. Helens! 1

You exploded in a spectacular fashion 30 years ago today! If I’d thought about it, maybe I would have tried to bump my wedding 4 days earlier just so I could have a shared anniversary. …just kidding. Mostly. There’s going to be less than normal going on in this blog for the next couple of ...

Volcano cam 1

This is pretty cool: Volcano cam of the Eyjafjallajoekull volcano, courtesy of Vodafone Iceland. And there’s enough going on with the eruption that a second vent has opened up. That’s some pretty exciting stuff! Not quite sure how I feel about chefs cooking meals over the lava. I mean, I guess if there’s not much ...

Volcano for Monday

Italy is one of those places where you may think about volcanoes (hello, Pompeii), but you don’t tend to consider tsunami hazards. Apparently they’ve got a real doozy, though, in the form of the Marsili Volcano. It’s an undersea volcano, and there are concerns that an eruption (and the subsequent likely collapse of its sides) ...

Volcano for Monday

Eyjafjallajoekull volcano in Iceland is erupting, and there are some lovely pictures of it. This is not really surprising; Iceland sits on top of a hotspot and really has a lot in common with Hawaii, at least geologically speaking. There is apparently also concerns that this eruption could wake up another nearby volcano, Mount Katla, ...

Volcano for Monday

Mud volcanoes in Pakistan, courtesy of NASA’s image of the day. (It was the image of the day for yesterday, actually, but let’s not be too picky.) And thankfully, unlike the Lusi Mud Volcano, these guys weren’t created by human carelessness and aren’t slowly engulfing a city. Pakistan actually has quite a few mud volcanoes; ...

Volcano for Monday

How about Mammoth Mountain this week. It’s quite the pretty mountain, and sits right next to Long Valley Caldera. Now, the cool thing is that this volcano formed pretty rapidly – in about 2000 years, which is fantastically fast for an 11,000 foot volcano – during an eruptive sequence of the caldera. A study has ...

Volcano for Monday

How about Mt. Churchill, a very pretty glacier-covered stratovolcano1 that’s just on the Alaska side of the Alaska/Yukon border. It’s not far from the coast either, and is yet another volcano that sits on the subduction zone around the Pacific rim. It hasn’t erupted in the last thousand years. All of this, of course, is ...

Volcano for Monday

It’s a twofer: the NASA Earth Observatory captured Klyuchevskaya and Bezymianny on Russia‚Äôs Kamchatka Peninsula erupting simultaneously. Pretty cool stuff. Like Sakurajima last week, both of these are composite volcanoes that live on the rim of the Pacific plate, which is a zone of active subduction. Volcanic rumblings in that area are never a surprise. ...

Lusi mud volcano: a drilling disaster

Strongest evidence to date links exploration well to Lusi mud volcano – this is quite the debacle. Obviously, there are safety concerns to be discussed regarding any sort of economic drilling. (Such as the long talk back in December about hydraulic fracturing. I think this one scores extra style points, however. There’s something impressive about ...
