Abstract
The Dinar earthquake (Ms= 6.1, USGS‐PDE) of 1 October 1995 occurred on the NWSE‐trending Dinar Fault. The earthquake is associated with a 10‐km‐long surface rupture with predominantly normal faulting. The mainshock was preceded by a series of foreshocks that started 6 days before the mainshock and included two Md= 4.5 events. The mainshock source mechanism derived from the inversion of broad‐band P waves revealed that two sub‐events occurred on a NW‐SE trending normal fault with a small strike‐slip component. According to the source model estimated in this study, the first rupture started at a depth of about 8 km and reached to a depth of about 12 km propagating north‐west. The total seismic moment found from the inversion of P waveforms is 2.0 times 10 18 Nm. The seismic moment of the second sub‐event was about four times larger than the first one. Field observations, GPS measurements and slip vector obtained from the inversion of broad‐band P waveforms suggest that the NW‐SE trending Dinar Fault is due to the internal deformation of SW Anatolia moving south‐westwards.
