I am back from our trip into the Mountain West – and it was great (see some of the pictures below). We hit Yellowstone, the Grand Tetons, the Tobacco Root Mountains, Glacier and Craters of the Moon – and the weather held out on us just fine. This week is the last week before classes…

Mt. Hood in Oregon, taken August 2008. Image by Erik Klemetti. Click on the image to see a larger version. Quick news! I’m not going to go into too much depth right now about the recent study published in Nature Geoscience on Mt. Hood in Oregon – I plan to talk about it more in…

Lots of little pieces of news I’ve run across … time to play a little catch up. Stromboli: A volcano after Don Ho’s heart. Every once in a while, my RSS feeds will dredge up some articles from years gone by … and this week there were two New York Times pieces that are a…

Climate, volcanism and the Andes

The northern Chilean and southern Peruvian Andes are full of volcanoes that look stunning – I mean, jaw-dropping details of volcanism litter the landscape. The reason for this is two fold: (1) there is an awful lot of volcanism in the northern Chilean/southern Peruvian Andes (as known as the Central Volcanic Zone) – and has…

Tourists hiking next to an active lava flow on Pacaya in Guatemala in 2006. I’m flying back to Ohio today after a successful few weeks of fieldwork/paper writing. Apparently I have a pile of tomatoes waiting in our garden in Granville … ! On to news: To go with the news that lava flows from…

Kilauea lavas on the move near Kalapana. Image taken July 17, courtesy of the Hawaiian Volcano Observatory. Some news over the last few days: The lava flows from Kilauea are moving with a vengeance right now, damaging roads and heading for some structures. The lava flows near Kalapana have moved almost 200 meters since Sunday,…

A few very quick hits: Ever-looming Mt. Rainier, with Tacoma, Washington in the foreground. PHIVOLCS is pondering whether to lower the Alert Status at Taal back to Level 1. The volcano has been on Alert Level 2 for the past month after increasing signs of potential eruptive activity. However, seismicity is down at Taal, so…

Serpentine (as known as serpentinite), the current (and potentially soon-to-be ex-) state rock of California. This does not have a direct connection to volcanoes, but it sure is about geology and the science in the news. State Senator Gloria Romero of California has sponsored a bill to change the California state rock from serpentine because,…

So, I’ve had requests on the blog to help to do some defining of volcanologic terms on the blog, so I thought I’d try a new column called Eruptions Word of the Day. I’m not sure how often it will run, but let’s give it a try. Eruptions Word of the Day for July 5,…

Have guests in town, so I’m a little busy, but you can hopefully keep entertained with the latest Smithsonian/USGS Global Volcanism Program Volcanic Activity Report. Chile’s Melimoyu volcano. The highlights (not including Taal and Eyjafjallajökull) include: Alaska’s Cleveland volcano has been reduced to and alert status of “unassigned” (used when a volcano is not closely…
