This will likely be my last new post for the next week or so. I’ll be off to my home town for a wedding and a reunion. If you’re jonesing for up to date volcano info, be sure to visit the Volcanism Blog or the European Volcanological Society news page. Feel free to post any…

Redoubt steaming away on May 4, 2009. Image courtesy of AVO/USGS Fairly quiet weekend (except for the start of the College World Series regionals … I do have a favored team*), volcanically speaking, but the ever-vigilant folks up in Alaska are keeping an eye on Redoubt as the eruption of 2009 continues. The weekly status…

Redoubt Update for 5/26/2009

Lenticular clouds forming over Redoubt on May 25, 2009. Image courtesy of AVO/USGS and sent to me by Eruptions reader Todd Russell. We haven’t talked much about Redoubt lately, so I thought I’d add a brief update. First off, the Alert Level at the volcano still sits at Orange/Watch status, meaning that although the volcano…

Pohutu Geyser in Rotorua, New Zealand. Image taken by Erik Klemetti in January 2009. It has been busy busy week for me, capped off today with a talk about my field work in New Zealand (see above), so I don’t have much to say. Not much new news today about the Saudi Arabian earthquake swarms,…

Tuesday Tidbits

Redoubt emitting a large steam plume in April 2009. Image courtesy of Calvin Hall. A few snippets from the world of volcanoes: The current eruptive cycle at Galeras continues to go strong. Officials with INGEOMINAS, the Colombian Geology Survey, believe the volcano will erupt again in the next few “days to weeks”. The volcano last…

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 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…

For those of you who might not be paying as close attention to Redoubt now as in the past, this is the latest from AVO: Redoubt’s 2009 eruption continues and appears to be gaining intensity. Seismic activity has increased markedly in the last 24 hours, showing stronger volcanic tremor and more frequent rockfall events. Minor…

Redoubt Update for 5/1/2009

Redoubt in April 2009 with Anchorage in the foreground (along with two F-22 Raptors). Image courtesy of Calvin Hall. It has been quite some time since I talked about Redoubt, mostly because the volcano has been in the “slow extrusion of a dome” mode that has not generated much beyond impressive steam (with some ash)…

Friday Flotsam

The weekend is rolling in and I might end up spending most of it in the 90+ degree California weather, so unless something big comes up (volcanically), I’ll leave you with a few news bits. Llaima Llaima in April 2009. Image courtesy of the NASA Earth Observatory This is a true color image of Llaima…
