Shaking during the 1964 Alaska earthquake was felt as far away as Seattle, Washington, and its tsunamis caused 129 fatalities and about $2.3 billion in property losses (2013 dollars).

Nearly 60 years after a magnitude 7.7 earthquake struck Lituya Bay, Alaska — leading to a tsunami that devastated the area — six U.S. Geological Survey geologists revisited the isolated region of Alaska, to pick up where their scientific predecessors left off.

A brain coral boulder eight feet in diameter stands 750 feet inland in the British Virgin Islands. Geologists say that the coral was brought ashore, probably alive, by an unusual tsunami or storm between the years 1200 and 1480.
