Abstract :

In March 9th, 2008 an earthquake of ML=5.1 occurred in Aryan-Shahr area, 45 km north of Birjand, East of Iran. More than 100 aftershocks were recorded within 8 days after the main shock. Distributions of aftershock have been occurring in ellipsoid limited area that the long axis of it has N120 trend.
Investigation of aftershock epicenter dispersal and the interpretation of aeromagnetic data reveal the presence a blind fault parallel to long axis of distribution ellipsoid of aftershocks, which has been named Gheysar blind fault. The Gheysar blind fault with ~39 km length with a near N126 trend which appears to has a thrust component, and gently dipping (~20°SW).
