On Novermber 20th, 1989, an earthquake with Ms=5.7 destroyed the Golbaf city in the Kerman province. To study the main shock and aftershocks, the Institute of
Geophysics, Tehran University, with cooperation of the Physics Department, Shahid Bahonar University of Kerman installed a temporary seismic network for about 40 days.
During this period more than 2500 events were recorded, among them 394 shocks were processed and located.
The epicenters of processed earthquakes were mostly distributed along the fault zone with 50 Ian length and 20 km width, and from 5 to 25 km depths. The mechanism
of main shock and the composite fault plane solution of aftershooks indicate thrusting, where the fault planes show a NW-SE striking with about 70° dip toward SW. It seems
that east parts of fault planes moved to the beneath its west parts
