AVO VOLCANO ACTIVITY NOTIFICATION

ALASKA VOLCANO OBSERVATORY INFORMATION STATEMENT
U.S. Geological Survey
Thursday, July 9, 2009, 2:46 PM AKDT (Thursday, July 9, 2009, 22:46 UTC)


REDOUBT VOLCANO (VNUM #313030)
60°29'7" N 152°44'38" W, Summit Elevation 10197 ft (3108 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW

As of today, July 9, AVO is standing down from 24/7 staffing of its operations center. AVO will have someone on duty in the office from 6 am to 9 pm seven days a week, but a staff scientist may not be in the operations center to immediately answer phone calls. At times we may not respond to inquiries as quickly as we have over the past several months, but will return phone calls or requests for information as soon as possible.

It is still possible for conditions at the volcano to change rapidly and seismic activity or other signs of unrest could escalate over time periods as short as 24 hours or less. The lava dome in the summit crater has not yet fully stabilized and may completely or partially collapse with little or no advance warning. A significant dome collapse would likely result in the production of hazardous ash clouds, possibly to aircraft flight levels, hot block and ash flows, and flooding in the Drift River valley. AVO will monitor for such activity on a 24/7 basis using alarms that send notifications to on call staff who will be able to respond quickly. AVO scientists will continue to examine monitoring data regularly and report on activity through our daily status reports and weekly updates.

AVO staff can be contacted by calling 907-786-7497. If no one answers at this number, calls will be forwarded to an answering service that will put you in contact with an AVO scientist. Usually, someone from AVO is able to respond to such calls within 10 minutes.
