Yellowstone New Year’s Eve Update

Yellowstone looks to be keeping everyone on their toes as we ring in 2009. The earthquake swarm reported earlier this week is continuing, with multiple events between 2-3.5 on the Richter Scale. Again, the folks monitoring the caldera – this time the Univ. of Utah – play down these events as normal for any active…

Photos of the activity at Koryak

Some more information is coming out about the activity at Koryak (aka Koryaksky) in Kamchatka. Russian geologist Alexei Ozerov says that the activity at Koryak (note: the image in the article linked here appears to have nothing to do with Koryak) has started with more power than the last known eruption of the volcano in 1956. He…

Is Yellowstone making plans for 2009?

2008 is almost finished and we’ve seen one of the few high-silica rhyolite eruptions in the past 100 years at Chaiten in Chile. Chaiten was definitely not high on the list of potential locations for a rhyolite eruption worldwide. However, Yellowstone Caldera in Wyoming definitely is high of the list because it has erupted a…

News is filtering in that Koryak (aka Koryaksky) Volcano in Kamchatka might be heading towards an explosive eruption. The details are scarce, but it seems that a breach on the northwest slopes of the volcano might cause an explosive eruption, however, it is not clear why this is. All this talk has caused the Petropavlosvk-Kamchatsky Airport…

The Holiday Pause

Well, the holidays (and its visitors) have derailed my blogging ability, so in that note, I will officially declare the Eruptions holiday until 12/30. Merry Christmas (or whatever you celebrate) to all the Eruptions readers – and I just hit the 100,000 visit mark, a great Christmas gift for me! – and I’ll catch up with…

AGU continued …

Today was a lot of talking and posters. Talking mostly about all things concerning Taupo and Okataina volcanism in New Zealand. Posters ran the spectrum from learning some nifty new tricks to extract zircon crystals from a crushed rock to what happens to clay when you breathe it into your lungs. I also learned that…

Another tidbit from AGU…

I was chatting with a fellow from AVO and he called the simultaneous eruptions of Kasatochi, Cleveland and Okmok a “once in a millennia” event. So, enjoy it! He also mentioned that the Kasatochi eruption released the most sulfur dioxide into the atmosphere since the 1991 Pinatubo eruption … but we had an idea of…

AGU Update 0.1

I don’t know if the live-blogging AGU will work out, but we’ll see. However, I did find out today that Chaiten was a compositionally zoned eruption. Good times!

When people think about volcanic mitigation, a lot of time is spent worrying about monitoring and science. There is nothing wrong with this as we need to know what the volcano has done in the past and what it is doing now to predict its future activity. However, a very important piece of the mitigation…

The last moments of Pompeii

Sometimes I wonder if we know more about the fates of people who died in a volcanic eruption over 1800 years ago than we do about most people who died in any given eruption this year. Not that there is anything particularly wrong with that – we’re fascinated by both volcanoes and Roman antiquity –…
