ruptured the greatest fault length of any recorded earthquake,
spanning a distance of 1500 km (900 miles). - The
portion of the fault that ruptured lies deep in the earth's crust,
in places as much as 50 km (31 miles) below the ocean floor. There
the two tectonic plates, which had been stuck together, suddenly
broke free, the upper plate sliding back upward and to the west by
as much as 20 m (65 feet) along the plate boundary.

- The Great Alaskan Earthquake 1964 - Magnitude 9.2 - Tsunami
Affects The most powerful subduction
zone earthquake in U.S. history, the 1964 magnitude (M) 9.2 Alaska
earthquake, caused tsunamis, 129 deaths in three states and an
estimated $2.38 billion in property losses (in 2017 dollars). Most
deaths and damage along the Alaska coast resulted from local
tsunamis caused by undersea landslides. The eruption of Mount St.
Helen's, in 1980, killed 57 people, damaged more than 185 miles of
roads, caused the cancellation of more than 1,000 airline flights
and resulted in $1.1 to $2 billion in economic losses.
