Does Eastern Washington receive as severe earthquakes like Western Washington?
No, earthquakes in Eastern Washington are generally not as severe as those in Western Washington. This difference is due to the distinct geological features and tectonic settings of the two regions.
Western Washington
Western Washington is situated on the Cascadia Subduction Zone, where the Juan de Fuca Plate is subducting beneath the North American Plate. This area is capable of producing very large and potentially devastating earthquakes.
The Western region of Washington State has experienced significant earthquakes, such as the 2001 Nisqually earthquake (magnitude 6.8). There have been many other examples of significant earthquakes in the region.
Eastern Washington
Meanwhile, Eastern Washington is less seismically active because it is located farther from the plate boundary. The earthquakes that do occur in this region are typically of lower magnitude and less frequent.
Of course, there have been some notable earthquakes, in Eastern Washington such as the 1936 Milton-Freewater earthquake (magnitude 6.1), they are not as common or as powerful as those in Western Washington.
