Open publisher page 2 citations

Abstract

This paper introduce a geometrical method called H-C method for fault plane identification. application of this method to Mw 5.1 Kerman, Iran, Earthquake. H-C method is a simple method, immediately applicable when a reliable earthquake location and its Centroid moment tensor solution (CMT) are available. In this study the Hypocenter location is obtained from two different agencies (local and global), ISC and IIEEES. Full waveform inversion for CMT solutions is done by ISOLA package. The result of this study shows that the fault plane of this Earthquake has a North-South dip which is in agreement with Previous Studies of this region (Talebian et al 2006; Hatami et al 2007). Although H-C Method, not yet broadly recognized as a useful tool for fault plane identification, its great potential is in simple linking of the independent pieces of short- and long-period seismic information.
