7. Tsunami and Liquefaction
A
30 foot Tsunami wave could inundate much of the lowlying
coast just minutes after the shaking stops. Some
30,000 Oregonians live in the coastal tsunami inundation zone of
a M9.0 earthquake. Run, don’t drive, to higher ground, says
Kevin Cupples, the city planner for the town of Seaside, Oregon.

On the coast, go to high ground immediately, advises Oregon Geology,
at least 15 m (50 ft) above sea level. Go inland away from the ocean as
far as possible. If you are unable to evacuate but are near a multi-story,
reinforced-concrete building, go to the third floor or higher.
