LARSE '93 - EVENTS RECORDED

During the four weeks of continuous recording (November 13 - December 11, 1993) stations recorded signals from ~160 teleseismic and ~400 local (Ml > 2.0) events. The data recorded with the sensors is velocity (100 volts/cm/sec) and is easily deconvolved back to earth motion assuming a "general" instrument type. Since the sensore were different, the instrument responses were also different. For arrivals from the northwest, rotation of the horizontal components results in components nearly parallel and perpendicular to the plate boundary marked by the strike of the San Andreas fault. The variation in back azimuths of the teleseismic arrivals has provided good coverage around the receivers, and their mostly steep (<20 degree) incidence angles preclude near-surface interference phenomena. Local events provide arrivals from which to obtain information about the San Andreas fault characteristics.
