Ash fall accumulation from Redoubt Volcano in Nikiski after March 28, 2009 eruption plume
Ash fall accumulation from Redoubt Volcano in Nikiski after March 28, 2009 eruption plumePhotograph of impacts from the volcanic ash fall out in Nikiski, AK from Redoubt volcano. This plume was generated during the March 28, 15:29 AKDT, 2009 event, and ash fall began at approximately 16:16 AKDT and lasted maybe 5 minutes.
