COSEISMIC DISPLACEMENTS OF THE 1992 LANDERS EARTHQUAKE SEQUENCE

We present co-seismic displacement vectors derived from Global Positio ning System (GPS) measurements of 92 stations in southern California. These GPS results are combined with five well-determined GPS displacem ent vectors from continuously tracking stations of the Permanent GPS G eodetic Array, as well as line-length changes from USGS Geodolite and two-color laser trilateration observations, to determine a self-consis tent set of geodetic data for the earthquake. These combined displacem ents are modeled by an elastic dislocation representation of the prima ry fault rupture planes. On average, the model residuals are about twi ce the estimated measurement errors.
