Two impressive eruptions going on right now: Soufriere Hills erupting on February 11, 2010. Image courtesy of the Montserrat Volcano Observatory. Soufriere Hills just keeps on raising the bar during its new eruptive period. The volcano on Montserrat in the West Indies produced a 15 km / ~45 000 foot ash plume as the summit…

News for the snowy (well, here) midweek: Lava flows from Kilauea surround an old structure at Royal Gardens in Hawai`i. A hearty thanks to all the Eruptions readers who offered advice on where to find a couple of great volcano videos I’ve been trying to track down. I think I’ve found copies I can get…

Submarine eruption near Japan

The plume from submarine volcano Fukutoku-Okanoba, erupting in February 2010. Almost a year after the Hunga Tonga Hunga Ha’apai eruption, where an undersea volcano sprang forth from the deep – quite spectacularly, we have new footage of another undersea eruption. Fukutoku-Okanoba, off the coast of Minami Iwo, started to erupt yesterday (or, at least, erupt…

Spotlight on two Japanese volcanoes

Sakurajima in Japan, erupting in December 2009. Image courtesy of Photovolcanica.com Richard Roscoe at Photovolcanica.com has just posted two great sites focusing on two of the most active volcanoes in Japan: Sakurajima and Suwanosejima. These volcanoes are almost constantly erupting with small strombolian events punctuated by occasional plinian eruptions. Sakurajima is on the island of…

All the news to start the week: Galeras with a grey ash-and-steam plume behind Pasto, Colombia. Well, after my article on Friday about Colombian volcanoes, Galeras must have decided it was left out. The volcano has been placed back at alert level Orange/II (eruption in days to weeks). An increase in seismicity and sulfur dioxide…

Somehow I missed a week of the SI/USGS Weekly Volcano Activity Reports and almost missed another. Here is this week’s update! Highlights (not including Chaiten, Soufriere Hills or Cleveland) include: The alert level at Galeras in Colombia was raised to Red after an explosion on September 30 and returned to orange … and then yellow…

Even the SI/USGS Weekly Volcano Report seems a little light — welcome to the dog days of summer! Highlights from this week’s report include: “Thunderous sounds”, incandescence and small plumes (hundreds of meters) with more frequent seismicity at Ibu in Indonesia. A sharp increase in sulfur dioxide output was noted at Mayon in the Philippines…

This is likely my last update until the end of next week sometime, so feel free to use it for any new volcano news you might see. Look for the Erebus Volcano Profile to be posted on Friday sometime, followed by the vote for the next Profile. Next time I post I’ll be (back) in…

Your volcano news! Thanks, as always, to the USGS/SI Global Volcanism Program. Highlights include: The alert level at Sakurajima was raised from 2 to 3 by the Japanese Meteorological Agency. This was due to the increasing frequency of explosions at the volcano, some of which produced ash plumes up to 1.8-2.7 km / 6-9,000 feet.…

All the volcano news that is fit to print, all thanks to the USGS/Smithsonian GVP! Highlights (not include Manda Hararo, Kilauea and Mayon) include San Miguel in El Salvador has been experiencing increased seismicity. The last time the volcano erupted was in 2002. A pilot spotted a ~10,000 foot / 3 km ash plume emanating…
