Today’s update will be relatively brief: AVO has returned Redoubt to Orange/Watch status after this weekend’s eruptions. The new dome continues to grow and this is accompanied by the usual volcanic seismicity associated with dome construction. We should expect…

Popocatépetl from the ISS on January 23, 2001 It might be (and is likely) just normal behavior for Popocatépetl in Mexico, but the volcano produced six plumes over the last 24 hours, according to a report out of Mexico City (in spanish). Officials from El Centro Nacional de Prevención de Desastres (The National Center for…

Redoubt Update for 4/1/2009

Photo courtesy of Calvin Hall. Taken from March 28, 2009, 50 miles from Redoubt. Redoubt continues to huff and puff, with an almost constant ash plume of ~15,000 feet / 5,000 meters. This after ~4 PM (Alaska Time), an explosion produced a 25,000 foot / 8,000 meter ash column that disrupted flights in and out…

Image courtesy of AVO/USGS by Tricia Joy Sadler. 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
