Lower Elwha is right down here by the Strait. The tsunami warning siren is on poles behind the shop, right in the central area, and is tested at noon on the first Monday of every month.
According to the Peninsula Daily News, the tsunami triggered by the 03/11 earthquake in Japan brought a 1.6 foot surge to La Push, and half a foot to Port Angeles harbor. The tribe has received an all-clear, and the Emergency Operations Center has shut down. Coast-wide we are still under a National Weather Service tsunami advisory, and according to the advisory the surge in the Port Angeles harbor was 1.3 feet. In this case I'd tend to believe the local paper.
Remarkable visualization of wave height, from NOAA.
