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.
