Multiple‐event relocation of earthquakes near the Gorda Rise ‐ Mendocino Fracture Zone intersection

Earthquakes along the southern edge of the Gorda plate and the Mendocino fracture zone that were relocated jointly generally tend to move 25 to 35 km southwest of their PDE and ISC locations. This has the effect of reducing the number of events occurring deep in the plate and increasing the number of events located on the Gorda rise as well as revealing a tightly grouped linear zone of activity extending along the Mendocino fracture zone. The resulting spatial pattern of seismicity is more consistent with recent models of the tectonics of the Gorda plate and the Mendocino fracture zone.
