Title

A-B VALUES FOR THE AHAR-VARZAGHAN EARTHQUAKE, NORTHWESTERN IRAN

Pages

  155-160

Abstract

 Seismic values are the main parameters in evaluating the neotectonic activity of a region. In August 11, 2011, two Mb=6.4 and Mb=6.3 EARTHQUAKEs occurred in AHAR-Varzaghan region within 11 minutes. Seismotectonic investigations imply that the faults generating the events are the young faults of the regions. Also, distribution of the epicenters represent a pattern consistent with the fault trends in the area. Temporal and spatial distribution of the EARTHQUAKEs (fractal analysis) as EARTHQUAKE pre-indicators together with A-B VALUES were used to assess the neotectonic activity and explore the seismic model of the AHAR area. Results show a sharp decrease in b-value, indicating that the main shock was associated with a zone of high strain rate. The seismic model presented for the AHAR area illustrates three periods after the main shock including: 1) an early quiescence Q1, 2) an aftershock period B, and 3) a late quiescence Q2. The rather increase in b-value during the Q2 period is interpreted to indicate stress decrease in the region.
