Global Volcanism Program
eklemetti | April 16, 2009Here's the latest Global Volcanism Program activity report for worldwide volcanism. Some of the highlights (beyond Fernandina and Llaima) include:
Vulcanian-style eruptions at Sakurajima, Japan. And guess what? There is a Sukarajima webcam! {Hat tip to Eruptions reader Jodie Morris for this link}.
Strombolian-style explosions and avalanches associated with lava flows at Arenal, Costa Rica.
A 10,000 foot / 3,000 meter ash plume from Dukono in Indonesia.
Satellite imagery exposed a thermal anomaly in the dome at Shiveluch on the Kamchatka Peninsula.
eklemetti | April 8, 2009Your weekly dose of volcanic activity. As a sidenote, you can now get placemarks for the weekly activity report via Google Earth. Select "Google Earth Placemarks" from the SI / USGS Weekly Volcanic Activity Report page.
Highlights of this week's report:
New explosions at Ebeko. See my article today for more details.
More evidence of increased activity at Nyamuragira and Nyiragongo, Congo. One interesting note is that scientists from the Goma Volcano Observatory noted that earthquake swarms usually precede eruption by 3-5 months.
I've seen very little news about this, but Pacaya in Guatemala…
eklemetti | April 1, 2009For those of you looking for real volcanic eruption news (no, there was no "Yellowstone eruption"), here is this week's SI/USGS Volcano Activity Report.
And speaking of April Fools Jokes, this is by far my favorite (mostly by its combination of volcanoes and baseball. How could you go wrong with two of my favorite things - hat tip to Fletcher for finding the article).
Highlights (beyond Redoubt) include:
Earthquakes, tremors and steam at El Reventador in Ecuador
12,000-15,000 foot (4-5 km) steam/ash plumes were spotted at Colima, the Mexican volcano.
A shockwave was felt 10 km away from…
eklemetti | March 25, 2009Its been a busy week for volcanoes between the headline capturing Tongan and Alaska eruptions. Catch up on what you might have missed with the latest SI/USGS Weekly Volcano Report (for 3/18-3/24). Highlights (beyond Hunga Tonga Hunga Ha'apai and Redoubt) include:
Galeras, Colombia has settled down a bit
More block-and-ash flows from the two dome complexes growing at Chaiten, Chile
Strombolian eruptions at Mt. Etna, Italy
Plumes of steam and minor ash were reported from Popocatépetl, Mexico
A small lahar was seen at Tungurahua, Ecuador
Ash plumes and incandescent tephra explosions were…
eklemetti | March 18, 2009I probably won't comment too much on these, but if you need a rundown on every volcanic rumbling on the planet in a given week, nothing is better that the weekly reports compiled by the USGS/Smithsonian Global Volcanism Program. You can check them out both through the GVP website and as a convenient RSS feed.

I've made it back from my trip to Washington DC. The Smithsonian Institution is quite a fun place to visit, especially if rocks are your ilk. Be sure to check out the wonderful mineral collection at the Natural History Museum. I only wish the Global Volcanism Program would have a more interactive (and visible) spot in the museum itself.
