Investigation of twelve earthquakes off the Oregon and northern California coasts

Creator:

Rinehart, Verill Joanne

Abstract:

Twelve earthquakes off the Oregon and Northern California coasts were used in this research to study whether faulting associated with these quakes was of the San Andreas type as observed in California. The first motions of the incident P and S waves recorded at various seismic stations in the Pacific...

A method for determining the source mechanism in small earthquakes with application to the Pacific Northwest region

Creator:

Gallagher, John Neil

Abstract:

A technique was developed in the present study to determine fault-plane solutions for small earthquakes. The method uses the direction and amplitude of initial P-wave motions recorded at a small number of seismic stations for epicentral distances less than 2000 km. Seismic arrivals recorded on short-period seismograms were identified as...
