ABSTRACT: In this research the fault
parameters causing the September 27, 2010 Kazeron Earthquake with a magnitude
of MW = 5.8 (BHRC) were determined using the random finite fault method. The
parameters were recorded by 27 accelerometer stations. Simulation of strong ground
motion is very useful for areas about which little information and data are
available. Considering the distribution of earthquake records and the existing
relationships, for the fault plane causing the September 27, 2010 Kazeron
Earthquake the length of the fault along the strike direction and the width of
the fault along the dip direction were determined to be 10 km and 7 km,
respectively. Moreover, 10 elements were assumed along the length and 7 were
assumed along the width of the plane. Research results indicated that the
epicenter of the earthquake had a geographic coordination of 29.88N - 51.77E,
which complied with the results reported by the Institute of Geophysics Tehran
University (IGTU). In addition, the strike and dip measured for the fault causing
the Kazeron Earthquake were 27 and 50 degrees, respectively. Therefore, the
causing fault was almost parallel to and coincident with the fault. There are
magnetic discontinuities on the analytical signal map with a north-south strike
followed by a northwest-southeast strike. The discontinuities are consistent
with the trend of Kazeron fault but are several kilometers away from it.
Therefore, they show the fault depth at a distance of 12 km from the fault
surface.
