California Doesn't Even Have To Fall Into The Ocean To Get In Trouble

California's Tsunami Risk. " In the open ocean, tsunami waves travel at speeds of up to 600 miles per hour... As the waves enter shallow water, they may rise rapidly. Typical peak wave heights from large tsunamis in the Pacific Ocean over the last 80 years have been between 21 and 45 feet at the shoreline... If a large earthquake displaces the sea floor near the coast, the first waves may reach the shore minutes after the ground stops shaking. There is no time for authorities to issue a warning." 40 years ago this weekend the Alaskan Prince William Sound earthquake and its ensuing tsunami killed over 120 people -- 12 as far South as California. Nothing compared to the thousands hit in the 1998 Papua New Guinea tsunami disaster, but still it's worth keeping an eye on California's tsunami risks. Or the entire West Coast's activity.
