Fissure vent eruption from Fernandina in the Galapagos Islands. In news that comes as a surprise to no one, the current eruption on Fernandina in the Galapagos is having some adverse effect on the wildlife in the Pacific archipelago. Numerous dead fish and sea lions have been seen in the ocean near the actively erupting…

Mount Pagan in the Mariana Islands erupting on April 15, 2009. Image courtesy of the NASA Earth Observatory. Up until fairly recently, a lot of volcanoes got away with erupting without anyone knowing the better. However, with all the “eyes in the sky” we have these days, even remote oceanic volcanoes get caught in the…

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.…

Wednesday Whatzits

Busy day so I probably won’t get to update much as we’re busy hosting Dr. Charlie Bacon, geologist for the USGS, here at UC Davis today. Dr. Bacon has written some seminal papers in his career and is probably the foremost authority of the evolution of Crater Lake/Mt. Mazama (speaking of which, >a new geologic…

Just a quick note before I’m off to this … Llaima The SERNAGEOMIN is evaluating whether the alert level at Llaima should be lowered to Yellow in the near future (in spanish). Seismic acitivity at the volcano have come down since the eruptions started a few weeks ago and most of the activity now seems…

Things settling down at Redoubt

Redoubt from Ninilchik, AK. Image courtesy of Calvin Hall. It has been a few days since we’ve talked about Redoubt. Well, it might be because the volcano has settled down for the past week, to the point that AVO put the volcano back to Orange/Watch status last week and hasn’t had to go back to…

Fernandina, Ecuador Fernandina erupting in 2009. UPDATE 4/13/09 at 12PM: The NASA Earth Observatory has posted a nice MODIS image showing the plume from the Fernandina eruption drifting out over the Pacific. We have a few more details on the ongoing eruption at Fernandina in the Galapagos Islands. Officials from the Parque Nacional Galápagos (PNG)…

Chaiten erupting on January 19, 2009. Image courtesy of the NASA Earth Observatory. It is hard to believe that we are less than one month away from one-year anniversary of the beginning of the eruption at Chaiten (and with it, the one-year anniversary of this blog!) The volcano in southern Chile is still erupting away,…

Fernandina volcano in the Galapagos. Fernandina in the Galapagos has entered a new eruptive phase according to the Geophysical Institute (GI) at the National University of Ecuador (in spanish). Satellite images show a new crater and ash column from the volcano and the GI will look for evidence of new lava flows beyond the “hot…

Active US volcanoes and volcano observatories After all the well-publicized words of “a certain governor in the lower forty-eight” (as Sen. Begich (D-AK) likes to call him) the “wasteful” spending on volcano monitoring improvements in the U.S. have become reality. Sec. of the Interior Ken Salazar announced $15.2 million dollars to modern the infrastructure of…
