The algorithm for absolute and relative location of microearthquakes has been implemented in the SIL system routine analysis. The software has been applied in a search of crustal faults, both in the Tjörnes fracture zone (TFZ) and the South Iceland seismic zone (SISZ). This work has been in cooperation with geologists within PRENLAB. Faults found from the microearthquakes show a remarkable agreement with the fault information available from sea bottom and land surveys []. These studies also indicate the power of the multievent location technique for discriminating the fault plane and the auxiliary plane. An example of the results using this algorithm is shown in Figures 3 and 4.
