So, I’m a little late with this thanks to a little hiatus, but I thought I would post the latest GVP Weekly Volcanic Activity Report. Thanks again to the Smithsonian, USGS and especially Sally Kuhn Sennert! Some highlights include: There were more ash explosions spotted at Ebeko in Kamchatka, producing ~1.8 km (5,900 foot) ash…

For all of you going into withdrawal now that Eyjafjallajökull seems to have quieted down, there are two eruptions of note that aren’t in the North Atlantic: Undated image of the Barujari cone at Mt. Rinjani in Indonesia. Arenal in Costa Rica – which is almost always sputtering away – had a more significant explosive…

This week’s USGS/Smithsonian GVP Volcano Update! Highlights include: A volcano I had never heard of in the Kuril islands is showing signs of life: Kharimkotan. Satellite images show a thermal anomaly at the summit of the volcano – its last known eruption was in 1933. Ash, sulfur dioxide and steam continue to erupt from Nyamuragira…

The latest news from the USGS/Smithsonian Global Volcanism Program Weekly Volcano Report … Highlights (not including Mayon) include: Strombolian eruptions and small pyroclastic falls at Arenal in Costa Rica. 3 km / 10 000 foot ash plume from Bagana on Bougainville Island in Papua New Guinea. Rumbling noises, ~4.5 km / 14 000 foot ash…

Friday Flotsam

The Q&A post will be coming over the weekend (there’s still time to send me a question!) Icy cold volcanoes (well, geysers) on Enceladus, a moon of Saturn. In the meantime, here are a few quick hits: Mt. Cleveland in the Aleutians had a small eruption. The plume was only ~15,000 feet / ~3 km.…

Arenal in Costa Rica, erupting in July 2007. Image courtesy of Arenal.net. Arenal in Costa Rica is one of the most active volcanoes in Central America. It is almost one of the most picturesque (see above) and, dare I say, touristy, volcanoes in the world. However, even volcanoes that seem “benign” like Arenal require special…

Here’s the latest news from the USGS and SI Global Volcanism Program. It might not record every little volcanic noise in the world each week, but nothing like getting all the major volcanic events summarized on a weekly basis. Highlights this week (not including Nyiragongo, Redoubt and Galeras): The eruption at Rinjani in Indonesia continues,…

Here’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.…

Dome collapse at Arenal

Today, I saw a report that a dome on Arenal in Costa Rica had collapsed last Friday (report in Spanish, but good picture of the event), producing a block & ash flow that left a 800-meter scar on the volcano‘s flank. No one was injured during the avalanche, but tourists were evacuated as a precaution.…
