House after earthquakePrevalence

King County, which includes Issaquah, is geographically located in an area known as the Pacific Ring of Fire, a distinctive zone marked by the prevalence of earthquake and volcanic activity.

Washington state is framed by the Pacific, North American, and Juan de Fuca plates, which are segments of the earth's crust.

A significant number of active fault lines or cracks in the crust have been identified in the Central Puget Sound area.


Our region has a long history of documented earthquake activity. The most recent significant activity was the Nisqually earthquake on February 28, 2001.

Direct impacts from earthquakes may include damages to structures, including buildings, pipelines, roadways and bridges. Secondary impacts from earthquakes are common and can include tsunamis / seiches and landslides.
