We used the cumulative misfit method to divide a data set with heterogeneous stress orientations into subsets with homogeneous stress directions. We propose that slope changes of the cumulative misfit as a function of earthquake number pinpoint the b

Geologic and seismic data reveal a set of parallel, active, strike-slip faults in east-central Alaska between the Denali and Tintina fault systems. The faults strike northeast to north-northeast, at a high angle to the bounding dextral fault systems,

The spatial pattern of earthquakes determined by a combined land and ocean bottom seismometer (OBS) network in the Kodiak Island shelf region differs systematically from the pattern determined by a land network and from locations determined by the In

Tilt observations from nearby local earthquakes in the magnitude range from 3 to 5 and larger teleseisms show an amplitude reduction with epicentral distance R of the form A (in seconds of arc)=10M-4.1×R-1. The result is compared to static elastic d

The compressional angle of isallo stress theory for the case of a cylindrical (circular and elliptic) and spherical subsurface inhomogeneity, assuming that the conjugate fracture surfaces are inclined at a Mohr angle of 30° toward the largest compre

The techniques of complex variables are used to obtain the solution for the two dimensional elastostatic problem of an elliptic inclusion, subject to an uniform stress field at infinity. It is required that the displacements are continuous and the st
