| Abstract | A local network of nine seismic stations recorded 53 microearthquake events in the Rendingan-Ulubelu-Waypanas (RUW) geothermal area betwen 13 December 1992 and 24 February 1993. Three main sequences of microearthquake swarm were identifkd. The hypocenters were determined Using a random analysis technique. There are four areas of microearthquake concentration, only one of them is located outside the geothermal field Most epicenters are &wed either SW-NE or SE-NW, following the two main structutal trends of this arm It is possible that some of these microearthquake swarms were caused by magma injections into deep fractures. |
