When was the last time a volcano erupted in Alaska?

What happened when Mount Cleveland erupted?
In May 2001, eruptions at Mount Cleveland sent ash plumes to an elevation of about 30,000 feet (about 9 kilometers). Airborne ash can damage the instruments and engines of overflying planes. When an ash eruption occurs, air traffic must be rerouted. This disrupts schedules and significantly increases fuel costs.
