Hawaii is threatened by tsunamis from circum-Pacific earthquakes and has been hit by major tsunamis from great earthquakes in the prior century in Kamchatka (1952), the Aleutians (1946 and 1957), Chile (1960), and Alaska (1964). Of these, tsunamis generated from great earthquakes along the Alaska-Aleutian Island arc are of particular concern due to their short (4.5–hour) propagation time to Hawaii, which presents the most limited time for coastal evacuation. Historically, the Aleutian earthquakes of 1946 and 1957 produced the largest tele-tsunamis observed in Hawaii (Lander and Lockridge 1989). The 1946 event (Mw 8.6) killed 159 people with...
