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…

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,…

Just a reminder, if you any questions for Sally Kuhn Sennert of the Smithsonian/USGS Global Volcanism Program – about the Weekly Report, about life at the GVP, about volcanoes – be sure to send them to me soon at . Now, on to this week’s update! Some highlights (not including Gorely): Lahars from Tungurahua in…

An explosion at the Santiaguito dome at Santa Maria in Guatemala. Now, we’ve been talking recently about funding volcano monitoring – specifically with the threat that KVERT in Russia will close down after today (June 30). Well, Jessica Ball over at Magma Cum Laude has another worthy volcano observatory that needs your help. The Santiaguito…

News! The summit crater lake at Gorely in Russia, taken on June 21, 2010. Image courtesy of KVERT. Eruptions readers have been abuzz about how KVERT will be closing shop (yet again) at the end of June. This would, of course, leave no local monitoring and expertise in the very active Kamchatka Peninsula and Kuril…

Sakurajima in Japan erupting in 2000. Sometimes, it is the volcanoes that erupt out of the blue that get all the attention, leaving the ones that are constant producers to be ignored by the fawning media. Sakurajima in Japan is just one of those constant erupting volcanoes that doesn’t get its just due. Well, over…

News for Monday! Ngauruhoe in New Zealand, showing the dark lava flows of basaltic andesite on the slopes of the young volcanic cone. Image by Erik Klemetti, taken January 2009. A couple pieces of news from two Russian volcanoes on the Kamchatka Peninsula: (1) last week’s report of activity at Gorely appears to be semi-substantiated…

This week went fast, didn’t it? The Baekdu caldera along the North Korean/Chinese border. The NASA Earth Observatory have been giving us a steady diet of volcanic plumes over the last week, including PNG’s Ulawun, Russia’s Sarychev Peak (a very faint plume), both an ASTER and Terra image of the summit region at Kliuchevskoi and…

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…

Crater lake at Eyjafjallajökull

The crater lake at Eyjafjallajökull as seen on June 11, 2010. Image from the Icelandic Met Office by Sveinn Brynjólfsson. After keeping us transfixed for almost two months this spring, Eyjafjallajökull has slowly drifted from the headlines. However, this doesn’t mean that interesting things – volcanologically-speaking – have stopped happening at the Icelandic volcano. For…
