A New York Times article (picked up by the Seattle Times) with an Ocean Shores dateline discusses proposed “vertical evacuation” buildings, at coastal schools and elsewhere. But, according to the report:
“Perhaps nowhere is more vulnerable than Ocean Shores, a community of 6,700 residents, with thousands more who visit in the summer to enjoy the miles of pristine beach next to thundering waves. The town has little elevation, and the tsunami that could accompany a 9.0 rupture would wash over all of it.
“People could try driving out, but officials expect roads to be buckled and sunken, or covered in power lines, trees and debris. The expected subduction would cause the entire area to abruptly sink up to 7 feet; the shaking could cause liquefaction of sandy soils before the tsunami reached shore.
“People could try running to high ground outside of town, but Ocean Shores sits on a 6-mile-long peninsula. Those who live toward the southern end would be about 8 miles away from high ground. Depending on their location, residents might have only 10 minutes before the wave started washing over them.
“‘In 10 minutes, there’s not that much time to go very far,’ Allen (Corina Allen, chief hazards geologist in Washington) said.
“The best option may be to get on a rooftop or to climb a tree. But many of the region’s buildings were not constructed to withstand such a quake, let alone a tsunami, which would be hurtling cars and logs and other debris.”
It‘s a chilling scenario…though it doesn’t mention the aging population of O.S., nor the scenario of a tsunami washing over the city during a packed summer weekend.
