Some 60 gravity stations have been established within and adjoining the Cerro Prieto geothermal field for the purpose of monitoring the small temporal changes due to fluid withdrawal and subsidence. Each station consists of a permanent concrete slab whose initial elevation has been determined by the CFE's second-order levelling survey. Data reduction has so far included reduction of meter readings to observed gravity values, dedrifting (using Longman's 1959 tidal formulas), calculation of gravity differences between bases and stations, and initial statistical evaluation (analysis of variance). 9 refs.
