Eruptions

Archives for March, 2009

Image courtesy of the Southern California Earthquake Center I have to admit, I’ve only been perpherially following the earthquake swarm currently going on in Southern California, near the end of one of the strands of the San Andreas fault out below the Salton Sea (see the bottom of the map above). The “Bombay Beach” swarm…

Goma after the 2002 Eruption of Nyiragongo The activity at Redoubt has captivated a lot of us, but in the grand scheme of things, its eruption are more likely to caused inconvenience and property damage rather than dramatically loss of life (unless something huge and unexpected occurs). However, the same cannot be said if Nyiragongo…

Taken 3/28/2009 at 3:29 PM Redoubt did not stray from its pattern of explosive eruptions producing >20,000 foot / 10,000 meter ash columns over the weekend. However, what did change was the wind, and because of that, Anchorage began to feel the effects of the volcano. Ash…

Redoubt Weekend Open Thread

Back in a former life, I was really into radio and music. Such an existence calls for many lists of rankings: “Best albums of 2004″, “All time greatest soul singers”, “Worst album covers of the 1980s”. And, although I love a list as much as the next person, I tend to find lists appalling. Why?…

Image courtesy of AVO/USGS by Game McGimsey Following the provided script, Redoubt erupted again last night, producing a 32,000 foot / 10,000 meter ash column that prompted a new ash fall warning for the Kenai Peninsula area. Thus far, though, there have been few reports of major damage being caused by the ash fall. Alaska…

Image courtesy of AVO/USGS, taken 3/23/09 I don’t have many details, but the largest eruption so far in this eruptive stage at Redoubt occurred at 9:24 AM (Alaska Time), producing a 65,000 foot / 20,000 meter ash column! Yes, you read that right, a 20-km ash column! This is by far the largest ash column…

Redoubt status returned to Orange

Image courtesy of AVO/USGS. Taken by Cyrus Read Based on the current levels of seismicity over the past 36 hours, AVO has returned Redoubt to Orange/Watch status from Red/Warning. This doesn’t mean that the eruption is over, just that things have settled down a bit. Flights to and from Anchorage have resumed as well. You…

Its been a busy week for volcanoes between the headline capturing Tongan and Alaska eruptions. Catch up on what you might have missed with the latest SI/USGS Weekly Volcano Report (for 3/18-3/24). Highlights (beyond Hunga Tonga Hunga Ha’apai and Redoubt) include: Galeras, Colombia has settled down a bit More block-and-ash flows from the two dome…

Redoubt seems to be setting its pattern for this part of the new eruptive period. There was another small explosion this morning that produced at 15,000 foot / 5,000 meter ash column that moved to the NNW. The seismicity has settled down since the early morning eruption today (3/25) as well. These types of explosions…
