Archival Gold: Imaggeo
I’ve run through quite a few of my royalty-free geoscience photo resources, but Erik Klemetti and Matt Hall mentioned a new one this week: Imaggeo, an open-access collection maintained by the European Geosciences Union. The photo collection is currently small, but the photo quality is top-notch.

Catching up
It’s been a while since my last post, for various reasons – family matters and beginning-of-the-semester hoopla among them. I hope to be blogging regularly again soon, but in the meantime, I’ll have to make do with posting a few of my favorite photos from this summer. (Which was also a time of interrupted blogging, but for natural-disaster-based reasons rather than human ones.)

Another posting delay…
Another posting delay…because the rest of the cross-country road trip went fine, but the food poisoning at the end of it didn’t. Once I’m off the lovely drugs and can think straight again, I’ll put something with more substance up. In the meantime, here are some more photos from the road:

Brief travel delay
I’m currently en route to this summer’s digs in Los Alamos, so posting will be light until I’m settled there. In the meantime, here are a few photos from the trip so far:

Archival Gold: FEMA Photo Library
It’s been a while since I did a photo resource post, and in light of the recent swarm of tornadoes and damaging storms, I though the FEMA Photo Library would be appropriate to highlight. The collection of photos on FEMA’s website does a great job of showing the human side of natural disasters – something that’s just as important to think about as the scientific side of hazard management and mitigation. The “Photo Collections” link doesn’t have many groups of photos yet, but a search on a particular hazard – floods, earthquakes, landslides, even eruptions – will turn up hundreds of photos, many recent (there are photos from last week’s tornadoes in the Midwest, for example).

Soufriere Hills Volcano: Recent deposits in 2010 and 2011
Last year I wrote about the February 2010 dome collapse deposits of the Soufriere Hills lava dome, and this year at the SHV: 15 Years On Conference I had the chance to revisit some of the very same spots. These deposits are mainly pyroclastic material (ash, dome rock and pumice), left behind after pyroclastic flows, surges, and a 50,000 ft (~15 km) high ash plume were created during a major collapse of the lava dome. These deposits extended the eastern coastline of Montserrat almost a km in the area of the old Bramble Airport, and surges were even observed flowing out over the ocean on the eastern side of the island. Here are a few before-and-after shots of the deposits:

Soufriere Hills Volcano: The Belham River Valley
It’s snowing again, so in order to avoid being depressed by the weather, I thought I’d post a few photos of the Belham River Valley on Montserrat. The Belham, which drains into the sea on the west side of Montserrat, channels both pyroclastic flows and lahars from the Soufriere Hills lava dome. Prior to the eruption, the valley held a number of houses and the island’s only golf course, but material from the eruption has since filled the valley bottom and made it unwise to live too close. Volcanic and volcaniclastic processes are constantly reshaping the landscape there, and having visited two years in a row (here’s the link to last year’s post about the Belham), I thought I’d see if any of my photos were good for before and after comparisons.

Archival Gold: Bureau of Land Management Image Library
The Bureau of Land Management is responsible for maintaining the public lands which don’t fall under the purview of the Park Service – which is more than 253 million acres spread over the entire country. They also maintain an Image Library with great photos of the holdings, as well as preservation, wildlife and fire management activities. There are a lot of geologic features in these photos, but it takes a bit of digging to find them (unless you know the name of the area you’re searching for). Here are some highlights:

Archival Gold: National Snow and Ice Data Center Photo Gallery
Most of our snow has been rained into nonexistence in the past few days, but as a last hurrah before spring takes hold, I thought I’d feature photos of very cold and snowy places. The National Snow and Ice Data Center is a part of the University of Colorado at Boulder, and they have a fantastic collection of photos of glaciers, iceburgs, ice sheets, sea ice, snow, Arctic/Antarctic expeditions, and other chilly subjects. Although not a government institution, the NSIDC does allow free use of properly credited photos in their gallery.

Pink and blue: Accretionary Wedge #32
Ann’s Musings on Geology is hosting this month’s Accretionary wedge, and she’s looking for a little color for Carnivale:
The theme will be “Throw me your ‘favorite geologic picture’ mister”Lets have the floats (submissions) ready on March 4th so it can roll on March 8. Carnival time is all about having a good time and having some fun so lets get some colorful, fun pictures submitted. Laissez les bons temp rouler!! (Let the good times roll!)
Jessica Ball is a volcanologist at the U.S. Geological Survey, researching volcanic hydrothermal systems and stability, and doing science communication for the California Volcano Observatory. She previously worked at the Geological Society of America's Washington DC Policy Office, learning about the intersection of Earth science and legislative affairs. Her Mendenhall postdoc and PhD focused on how water affects the stability of volcanoes, and involved both field investigations and numerical modeling applications. Her blogging covers a range of topics, from her experiences in academic geosciences to science outreach and communication to her field and lab work in volcanology.
