What the record says

NCEI’s account, from the sources it cites.

Redoubt's largest Holocene eruption occurred ca. 3600 yr BP when the summit of the volcano collapsed down the south flank of the volcano and formed a large debris avalanche (Beget and Nye, 1994). The resultant deposit extends 30 km down the Crescent River valley to the modern shoreline of Cook Inlet (Riehle et al., 1981). The Crescent River debris avalanche from Redoubt Volcano probably traveled at a higher rate of speed and displaced seawater as evidenced in several paleotsunami deposits found near Homer, AK.
