Mount Saint Helens in review

Image courtesy of USGS/CVO, taken March 8, 2005 from the Cascades Volcano Observatory, Vancouver, WA For those of you looking for something to relax with and read this weekend, you could wander over to the USGS website and download yourself a copy (for free and legally) of “A Volcano Rekindled: the Renewed Eruption of Mount…

Mauna Loa fire fountains in 1984 For those of you looking for some non-Redoubt-related volcano news, you can take a look at the 25th anniversary of the last eruption at Mauna Loa (there is some nice video footage provided by KHNL if you follow the link). By no means is this volcano “dormant”, but rather…

Two tidbits from New Zealand: – A recent survey of volcanoes in the Kermadec Arc north of New Zealand suggest that there is abundant – and recent – undersea volcanism. Scientists from University of Washington (one of my former homes) and Southhampton University (UK) explored a number of submarines volcanoes including Rumble II West, Rumble…

Chaiten Redux

UPDATE 2/19/2009 9:45 AM: Well, it seems that my hunch was at least partially right. Reuters (and Paula Narvaez, special envoy to the Chilean president) is calling the eruption as result of “what appeared to be a partial collapse of its cone.” So, we might have seen the oversteepening of the dome growing in the Chaiten…

The Anchorage Daily News has an excellent article today on the Drift River Oil Terminal, a depository for oil collected from the platforms in the Cook Inlet. This oil terminal stores at least 1,000,o00 barrels of oil (see article for why we’re not sure) and sits, well, at the base of Redoubt (see map below…

Chaiten update for 2009

It is hard to believe that the eruption at seem to come out of nowhere at Chaiten started over 8 months ago now, and apparently is still not showing many signs of abating. I did get a chance to see some great talks and posters at AGU last month about the Chaiten eruption, with the…

Ruapehu video help

I wouldn’t normally use this blog for something like this, but google has failed me. When I was in New Zealand, I saw a video on the 1995-96 eruptions at Ruapehu titled Witness to Eruption made in, I believe, 1999. It had some excellent footage of the eruptions in the 1990s as well as the…

One of the more impressive areas I visited while in New Zealand was the Waimangu Valley near Mt. Tarawera (above). The valley itself was created by blast explosions (phreatic explosions) during the 1886 eruption of Mt. Tarawera. These eruptions cut right down the axis of the rhyolite domes (most of which erupted ~1305 A.D.) and…

Back from New Zealand

I made it back from New Zealand yesterday after spending the last two weeks looking at some of the most remarkable volcanic landscapes you could imagine. I’ll add more detail soon for those of you interested in the volcanism of the North Island, but I’ll leave you with a picture of yours truly in from…

Two weeks in New Zealand

Right as Yellowstone is getting interesting (or at least had signs of interest), Eruptions is going on a bit of a break again starting January 2. This time it is because I’m off to the North Island of New Zealand to do some field work. I’ll be headed to Tarawera (hopefully both the 1305 and 1886…
