What’s the highest hill on your Alaskan island? Tsunami’s etc.

When there is a tsunami alert, folks go up to the volunteer fire department building next to the airport. 113 feet above mean sea level. Highest elevation on the island is around 3000 feet.

There are those who claim (no idea about the validity of such) that the bulge at the equator of sea water because of the spin ... due to a pole shift or meteor or some such will result in a Tsunami of 1,000-3,000 feet in many areas.

Time will tell.
