New study says U.S. East Coast faces variety of tsunami threats

By Douglas Main

November 17, 2012 NEW YORK - Although the risk is small, tsunamis are possible on the East Coast of the United States from a variety of sources, according to new research. And as Hurricane Sandy showed, the region is completely unprepared for a major influx of water, said U.S. Geological Survey researcher Uri ten Brink. The most likely source for an East Coast tsunami would be an underwater avalanche along the continental slope, according to research presented by ten Brink and others earlier this month at the annual meeting of the Geological Society of America in Charlotte, N.C. Ten Brink also outlined several other possible sources of tsunamis, including earthquakes and even collapsing volcanoes. An offshore earthquake of magnitude 4.5 or above could cause submarine avalanches and create dangerous tsunamis with waves higher than 26 feet (8 meters), ten Brink told OurAmazingPlanet.

1. That applies to the west coast too.

In here somewhere : https://www.eeri.org/wp-content/uploads/FinlRept.pdf

I've seen a TV documentary on the specific subject of that area. Its was estimated the warning time would be c. 10 minutes.
