Eruptions

Archives for May, 2009

Things were relatively quiet, volcanically speaking, over the weekend and that reminded me, it is just about time to vote on the next in my Volcano Profile series. We’ve had two volcanoes featured so far: Rabaul in Papua New Guinea and Hood in Oregon. Take a look at the list below and vote for the…

Things are busy – both volcanically and personally – so I’m going to just give you some links to a bunch of exciting/interesting/insane news: West Mata erupting on May 5, 2009 in the Lau Basin. According to a bunch of news sources, the eruption at Fernandina in the Galapagos is over (in spanish). That being…

If you haven’t noticed, I like to use pictures of volcanoes on this here blog. Sometimes I use pictures I’ve taken, but I know that many of you have pictures that would put mine to shame. So, I’d like to ask you, Eruptions readers, if you would send me pictures of volcanoes – erupting or…

Anak Krakatau in Indonesia. Eruptive activity is definitely on the uptick at Anak Krakatau. The Jakarta Globe is reporting that the volcano is “spewing molten lava 1000 meters in the air“. I’m not entirely sure if that is accurate or that the volcano is throwing volcanic bombs or tephra that high. The head of the…

All the eruptions fit to print from the Smithsonsian/USGS GVP Weekly Report. A few highlights (not including Redoubt, Rinjani and Slamet): Multiple ash plumes from Galeras (Colombia), some producing noticeable ash fall up to 35 km from the vent. The Alert Level at Anak Krakatau, Indonesia was raised to 3 (out of 4) after a…

The Geysers Geothermal Power Plant Eruptions reader (and former hallmate at Oregon State) Ed Kohut sent me a message today pointing out that there is an ongoing earthquake swarm in the area of the Geysers in northern California. Now, I don’t know what the normal seismicity is underneath the Clear Lake area and this area…

Nyiragongo as seen from Goma, Congo in 2002. There isn’t much to go on so far, but there are indications that an eruption has started at Nyiragongo in the Democratic Republic of Congo. Satellite images has found “thermal anomalies” at the summit and along a 3-km swath of the eastern and western slopes. The report…

Some brief tidbits from the volcanic realms: Active volcanism at NW Rota-1 Kilauea? Explosive? You might think of Kilauea as a volcano that generates impressive Hawaiian-style eruptions with fire fountains reaching 100s m and dazzling lava flows, but Don Swanson at HVO sees evidence of a big explosive event at Kilauea. This eruption was ~1,000-1,600…

The clock is ticking for the new dome growing at Redoubt to collapse. What will happen if/when it does collapse? Good question! The new dome at Redoubt. Image courtesy of AVO/USGS, taken by Game McGimsey, April 30, 2009. Most likely, the following will occur: First, extrusion of lava will cause the dome to over-steepen, precipitating…
