Mt. Redoubt erupted last winter and spring, sending volcanic ash across Cook Inlet to many communities along the Kenai Peninsula and Anchorage Bowl, as well as to parts of Lake Clark and Katmai National Parks.

The Alaska Volcano observatory provides a number of online services for those interested in keeping tabs on Mt. Redoubt , and all of the active volcanoes in Alaska. The main page for Mt. Redoubt shows the current status, as well as providing links to webcams , webicorders (online representations of seismic data, provided in near-real-time) and trajectory plots, which show the forecast direction of the ash plumes, in the event of an eruption. In addition there is a website for your mobile phone that also provides links to this information, and you can find that here .
