|Debris-avalanche, volcanic avalanche, or landslide: ||
From Beget and others (2002): "The largest known eruption of Shishaldin Volcano occurred about 9,500 years ago when the summit of Shishaldin Volcano collapsed to produce the large Cape Lapin debris avalanche. This giant landslide traveled more than 20 kilometers north to the Bering Sea, burying the northwest flank of Shishaldin Volcano and nearby areas of Unimak Island. The modern symmetrical cone of Shishaldin has completely regrown since this collapse event (Begét and others, 1998)."
