Hunga Tonga-Hunga Ha'apai, one of many submarine calderas NE of New Zealand in an island arc, has begun causing some problems for flights in the area. What started as a minor steam and ash eruption has now turned into a semi-major eruption in the area. Steam and ash clouds are reaching extraordinary heights, and the ongoing eruption is rapidly building a new island.Photo from Volcano-discovery.comResidents have reported that the eruption plume was changing hourly from white steam, to black ash [...]
Really good discussion in yesterday’s evening Tectonophysics poster session! Among several points of interest, I met a young PhD student from Montpellier who is doing both fieldwork and numerical modeling in Alaska, dealing with the tectonic configuration of thrust and strike-slip fault interference. This caught my attention immediately because I have been doing both numerical and (mostly) analogue modeling of this type of interference for some time now . Mostly we’ve been looking at the [...]
I missed this retrospective meme last year (as I also did in 2011), but here it is, back again, per DrugMonkey:
The rules for this blog meme are quite simple.
-Post the link and first sentence from the first blog entry for each month of the past year. I originally did this meme, after seeing similar posted by Janet Stemwedel and John Lynch. Prior editions
Here is the outfall of the Pebble Mine and Mt Polley Mine debacles. A report on the Seabridge Gold’s KSM Mine in BC. The report is authored by Salmon Beyond Borders, a coalition of Alaska Native tribal members, commercial, sport and subsistence fishermen, and other groups, in consultation with Earthworks. The press release is at this link. The
When glaciers erode landscapes, they often leave behind characteristic U-shaped valleys. This week’s Monday Geology Picture shows a U-shaped glacial valley on the Seward Peninsula in Alaska. This valley is located just outside of the gold mining town of Nome. Does anyone else have good pictures of U-shaped
Guest bloggers: Zach Downes & Wilson Nelson For me, the trip started in Juneau, Alaska. We arrived in Juneau late with a couple of things to take care of the next day before getting in a small plane and heading to Gustavus, Alaska where Glacier Bay National Park is based. We needed food, XtraTuf boots,
Last Tuesday, Alaska voters rejected a referendum proposal that would have repealed oil and gas production tax legislation signed into law by Governor Sean Parnell in May 2013, known as the "More Alaska Production" Act.
With the referendum rejected, we thought our readers would appreciate a review of what this might mean for the oil and gas industry in Alaska. A recent article we published in Alaska Business Monthly discussed in detail the trends and specifics of the production tax credits that [...]

One day last week I found myself feeling kind of punky. I woke up a bit dizzy, and found that my blood pressure was higher than it usually is. For that reason, I decided to take a sick day. Unknown to me, though, while I was laying about in my government housing unit worrying about my blood pressure, I missed meeting Mary and Brad.When I returned to work the next day, my blood pressure was back to normal but I was still feeling a bit out of sorts. As soon as I walked in the door, another ranger [...]
Gulf of Alaska 2004 Expedition. NOAA Office of Ocean Exploration
This week I have been researching images from deep-sea video on the home page for the NOAA Photo Library, which has housed ALL of the deep-sea and other imagery from NOAA's deep-sea expeditions since 2003, including those of the Okeanos Explorer!
Many of you know that I have participated in the last two
A powerful but deep earthquake occurred in the western portion of the Aleutian island arc at 11:53 AM local time on June 23. The earthquake was beneath the Bering Sea near Little Sitkin Island, Alaska at depth of 114 kilometers. A tsunami warning was

An article on the Anchorage Daily News website explains why the oil and natural gas resources of Alaska are difficult to develop because the rules applied in other parts of the United States do not work well in Alaska’s unique

Ha, I predicted this earthquake for last Christmas, although I thought the earthquakes were marching to the north, and not south. So, not much of a prediction...
The 'Long March" is the natural series of earthquakes along this huge strike-slip fault. We had 2 M7+ earthquakes, and they were marching north. The next one I predicted would be in the armpit of Alaska. Three big M7.5's

Heliolites is an interesting coral that I thought was confined to the Silurian period, So I was surprised when my friend Nils sent me a specimen from the Devonian of Germany in a recent exchange. The specimen below comes from the Junkerberg Formation (Devonian, Eifelian stage) near Rommersheim, Germany.Previously I've blogged about specimens from the Silurian of Gotland, Sweden and Louisville, Kentucky. A search of the Fossilworks site (formerly Paleodb.org) shows that Heliolites is known up [...]
