There is an estimated 5-7 minutes of shaking or rolling that will be felt along the coastline with the strength and intensity decreasing the further inland you are. 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. According to the Global Historical Tsunami Database, since 1900, over 80% of likely tsunamis were generated by earthquakes. Large tsunamis have occurred in the United States and will undoubtedly occur again. Last year, the governor of Oregon signed a law that, among other things, overturns a 1995 prohibition on constructing new public facilities within the tsunami-inundation zone. Earthquake experts in the Northwest have said the Cascadia Subduction Zone is due for a large, undersea seismic event possibly soon which could trigger a catastrophic earthquake and tsunami along the Oregon Coast.
