Connecting earthquake nucleation in basement rock to fluid injection basal, sedimentary reservoirs, depends heavily on choices related the poroelastic properties of fluid-rock system, thermo-chemical effects notwithstanding. Direct constraints these parameters outside laboratory settings are rare, and it is commonly assumed that layers isotropic. With Arbuckle wastewater disposal reservoir Osag...

Detailed analyses of teleseismic surface waves and body waves from the Guatemala e rthquake of February 4, 1976, show the following: (1) Left lateral displacement along a vertical fault with a strike varying from N66øE to N98øE is consistent with the teleseismic data. (2) The seismic moment was 2.6 X 102? dyn cm. The directivity ofthe surface wave radiation i dicates an asymmetric (1:2.3) bilat...

S U M M A R Y Since the end of the 1970s, teleseismic waves are used routinely to infer the first-order characteristics of the event (location, depth, duration, focal mechanism), but finding the second-order kinematic parameters (spatial distribution of slip, rupture velocity and more basically the discrimination between the fault plane and the other nodal plane) of distant events remains a dif...

DISCRETE TIME SOLUTION OF PLANE P-SV WAVES IN A PLANE LAYERED MEDIUM by Clint Wellington Frasier Submitted to the Department of Earth and Planetary Sciences in partial fulfillment of the requirement for the degree of Doctor of Philosophy. For plane waves at normal incidence to a layered, elastic medium both the forward and inverse discrete time problems have been previously solved. Here, the fo...
