We have surveyed 107 monuments in a 30x45 km area around Parkfield California in June 1992 and again in May 1993. We are analyzing the data from these observations and will present the details of the method and the displacements measured from 1992 to 1993.
Imperceptible to human senses, California continues to deform every day at a rate comparable to the growth of fingernails. Convection in the mantle under the Earth's solid crust forces continental-size.

Earth rotation data were obtained with GPS during the EPOCH '92 campaign in the summer of 1992. About 10 days of data were acquired from 25 globally distributed stations and a constellation of 17 GPS satellites.
