The most important clue linking the tsunami in Japan and the earthquake in the Pacific Northwest comes from studies of tree rings (dendrochronology), which show that several "ghost forests" of red cedar trees in Oregon and Washington, killed by lowering of coastal forests into the tidal zone by the earthquake, have outermost growth rings that formed in 1699, the last growing season before the ...
Stumps of trees at the Neskowin Ghost Forest. The Neskowin Ghost Forest is the remnants of a Sitka spruce forest on the Oregon Coast of the United States. The stumps were likely created when an earthquake of the Cascadia subduction zone abruptly lowered the trees, that were then covered by mud from landslides or debris from a tsunami. [1]

A fault off the Pacific coast could devastate Washington, Oregon and Northern California with a major earthquake and tsunami. Researchers mapped it comprehensively for the first time.
The notices advised residents a tsunami could arrive along the coast starting near Fort Bragg at 11:10 a.m. local time and move along the coast in northern California and southern Oregon, arriving ...
A tsunami warning was issued for the coast from Davenport, California, to the border between Douglas and Lane counties in Oregon. The Tsunami Warning Center canceled the warning at about 11:55 a.m .
The Oregon Department of Emergency Management estimates shaking would last 5–7 minutes along the coast, with strength and intensity decreasing further from the epicenter. [1] It is a very long, sloping subduction zone where the Explorer , Juan de Fuca , and Gorda plates move to the east and slide below the much larger mostly continental North ...
Exterior of the lab. The first wave research equipment was the wave flume. [3] It is 360 feet (110 m) long, 12 feet (3.7 m) wide, and 15 feet (4.6 m) deep. [3] It is used to simulate the waves of the ocean, and creates 5-foot-high (1.5 m) waves with currents strong enough to surf on. [3]
