How many tsunamis does Alaska get a year

Here we report geological evidence for large tsunamis, occurring on average every 300–340 years, near the source areas of the 1946 and 1957 Aleutian tsunamis.

Explanation:

There are about 20,000 earthquakes in Alaska every year (Alaska Earthquake Center). “Great” earthquakes (larger than magnitude 8) happen in Alaska on average once every 13 years, while magnitude 7 to 8 earthquakes occur on average once every year.
