## Abstract
Abstract Nowadays microearthquake or microseismic monitoring is powerful tool to investigate and evaluate the geothermal field. Each event of microseismic can be associated with permeable zone. One parameter can be used as a fracture indicator is Poisson’s Ratio. The simple method to get information about Poisson’s Ratio is Wadati Diagram. We applied this method in “A” Geothermal Field with 2 month recording microseismic data. The range of Poisson’s Ratio distribution is 0.11197 – 0.468463. The lower Poisson’s Ratio associated with un-fractured rocks and the higher indicate fractured rocks.
