TRIFUNAC, MD A three dimenslonal dislocation m~dal for the San Fernando, California, earthquake ~ Febrmary 9, 1971. IOF, 3T, 42R. BULL. SEI~4. SOC. AM.V6~, N1, FEB. 1974, P149"172. The three-dimensional dislocation modal described by Haskall has been examined in this paper as a possible basis for modelling the earthquake fracture ~ocess. The results of a p r a l i m i r ~ analysis indicate the possibility of deciphering the details of complicated dislocation ~ocesses and demonstrate how valuable the near field strong motion data are for acquiring an underatsmdlng of earthquake source mechanism, of ~redlction of strong ground shaking for earthquake engineerirg purposes, and for development of sensitive techniques for discrimination between explosive and tectonic sources.

V64, N1, FEB. 1974, P187- 203 • Microearthquakes along the Elsincre fault zone~ were monitored during ~ ar~ fall of 1972. The recorded rates of seismic activity show a marked increase goir~ from north to south along the fault. First motions of the located earthquakes indicate a complex pattern of faulting along the fault. In comperlaon to the San Jacinto Fault, the Elsincre Fault shows very little strike-slip displacement and is a seismically quiet area. 1997 ROGERS, AM ENVIRO~4E~TAL RES.CORP.LAS ~EGAS, USA KATZ, LJ ENVIRONMENTAL RES.CORP.LAS ~EGAS, USA BENI~T±,TJ ENVIRONMENTAL RES.CORP.LAS ~EGAS, USA Topographic effects on grotmd motion for incident P waves: a modal study: 16F,21R.

It was found that amplifications as large as 35 per cent may occur in the time domain for a wideband input with predominant w a v e l e r ~ equal to the width of the scatterer base.

A two-layer model has been c o n s ~ t e d in order to describe water flow over an impermeable boundary. The modal consists of vertical flow through an umsat~ated layer and flow along a bour~lary in a ssturate~ layer. Equations are given for the nonsteady case, where the gradient of the thickness of the saturated isyer is small compared with the slope of the impermeable boundsry. It is shown that in most cases t~e d/scharge from shallow snowpacks will pressure the diurnal cycles of input at the st~face, altho1~gh for deep sr~q~acks~ the diurnal cycle is smouthed and only long term responses sre expected.
