ESRL's VACT Used to Evaluate Augustine Volcano Eruptions
Mt. Augustine on Augustine Island, located approximately 180 miles southwest of Anchorage, Alaska, has erupted a total of eight times over the past week. The Alaska Volcano Observatory (AVO) reported explosive activity twice on January 11, five times on January 13-14, and most recently on the morning of January 17. The Volcanic Ash Coordination Tool (VACT) developed by ESRL's Global Systems Division (GSD) was used in real time to evaluate location, areal extent, and movement of ash. This new technology provides a baseline set of meteorological displays, forecaster productivity tools, and graphical and text collaboration capabilities. The VACT made it possible to facilitate timely and coordinated responses to various agencies during these recent events. A Significant Meteorological Advisory, Marine and Public Ashfall Advisories, and a Graphical Meteorological Impact Statement were issued. As Mt. Augustine is still active and explosive activity is expected over the next several days or weeks, GSD's Greg Pratt has been asked to train staff at the Alaska Aviation Weather Unit, the Anchorage Center Weather Service Unit, and the AVO. He will also monitor how the VACT is being implemented during a live event.
