Name: Relocated Earthquakes >1M

Display Field: EARTHQUAKE_MAGNITUDE

Type: Feature Layer

Geometry Type: esriGeometryPoint

Description: The Washington Geological Survey relocated earthquake hypocenters for events greater than magnitude 1.0 with depths shallower than 25 km throughout Washington State. Relocating earthquakes gives a better estimation of the three-dimensional position of the earthquake. These improvements are made by careful review of the data by a skilled analyst. The original earthquake data (P and S-wave arrival times) were obtained from the Pacific Northwest Seismic Network (PNSN) catalog and the earthquakes were relocated using the ‘hypoDD’ computer program. The hypoDD program uses a double-difference earthquake relocation algorithm of Waldhauser and Ellsworth (2000) to relocate earthquake clusters relative to one another, in some cases revealing previously unobserved linear trends. Linear trends of earthquake locations within a region can help scientists locate unmapped faults.
