Wave heights of four of these distant tsunamis reached 1-5 m (3-16 ft), causing damage to coastal communities and in be felt along the coastline with the strength and intensity decreasing the Why Do Cross Country Runners Have Skinny Legs? Four years ago, I wrote an article for this magazine about a little-known fault line just off the coast of the Pacific Northwest that periodically produces earthquakes of magnitude 9 and greater which, in turn, produce tsunamis equal in enormity to those that struck Indonesia and Japan. When they strike land, most tsunamis are less than 10 feet high, but in extreme cases, they can exceed 100 feet near their source. However, while there is no indication it could happen soon (but could), there are scientifically sound reasons for concern that at some point a mega-tsunami could engulf the entire East Coast with a wave almost 200 feet high sweeping everything and everybody up to 20 milesinland. However, specific areas are highly impacted by the tsunami: Cutler City, southwest of Devils Lake near the mouth of D River, and a few discrete areas in the Taft neighborhood.

That region is known as the tsunami-inundation zone, which is exactly what it sounds like: the area that, according to seismologists, will be completely underwater when the wave arrives. Oregon has the potential for a 9.0+ magnitude earthquake caused by the Cascadia Subduction Zone and a resulting tsunami of up to 100 feet in height that will impact the coastal area. Rather,geologic evidenceis accumulating that the Cascadia subduction zone is poised between major earthquakes. But the quakes recur only every few thousand years. Both of the secondary wavefronts initially travel parallel to shoreline, but their paths of travel curve (refract) toward shore. The last two damaging tsunamis were in 1964 as a result of the Great Alaska Earthquake and in 2011 as a result of the Great East Japan Earthquake. It serves not only as a common conception but also as a working assumption for many tsunami models (including models employed during the first phase of this study).
