Tsunami Could Hit Seattle
Over one thousand years ago, a tsunami devastated the area where Seattle exists today?according to computer modeling?and researchers think it could happen again.

The tsunami reached heights of 9 to 23 feet and traveled 18-28 miles per hour, and swept almost 100 feet into shore in some places. A wave that size can lift cars off the ground. Add those problems to gas lines severed after a quake, “and you’ve got the makings of a disaster,” says tsunami researcher Emile Okal.
