A future earthquake off the coast of Alaska could unleash a devastating tsunami on ports and cities along the US Pacific coast, British scientists have warned.
Such an event could dwarf the great 1964 Alaskan earthquake, which triggered waves more than 40 feet high, research suggests.

WASHINGTON (Reuters) - Scientists have underestimated the potential for a giant quake and tsunami that could swamp much the U.S. northwest and Canadian west coasts, British and U.S. researchers said on Monday.

Geological evidence suggests there have been earthquakes in the past that were even stronger than a magnitude 9.2 quake -- the second-biggest ever recorded -- which caused a 42-foot-high (12-meter-high) tsunami in the Gulf of Alaska in 1964, they said.
