one of the methods for the determination of focal mechanisms of earthquakes is the linear inversion of moment tensor in time domain. that method is used here for determining of the focal mechanisms the darbe astaneh silakhor earthquake of 31 march 2006 and two of its foreshocks and six aftershocks with local magnitude more than 4. the data of six broadband stations of the international institut...

the purpose of the present study is to compare the changes in b-value parameter using frequency-magnitude distribution for the data before and after the silakhor earthquake by gutenberg-richter relation. the variations of b-values are investigated using broadband iranian national seismic network center (bin). besides, spatial and time variations of the parameters were analyzed. the spatial vari...

the source parameters and focal depth of the destructive mw 6.5, 31 march. 2006 iran- silakhor earthquake, the two largest foreshocks and a major aftershock are determined using broadband data from a seismic network in iran based on a time-domain linear moment tensor inversion. the earthquakes occurred in the zagros suture zone in western iran. waveform inversion of the selected events estimate...

INTRODUCTION: Natural disasters in rural settlements are responsible for a broad range of financial and human losses. In this regard, the resilience approach has gained renewed attention to minimize the disruptive impacts of natural catastrophes. Therefore, adequate knowledge about the status of resilience enables us to take efficient measures to reduce resultant injuries and destructive effect...

the zagros fold- thrust belt as a part of alpine- himalayan orogenic belt, is one of the most active continental collision zones on the earth, which extends from the tarus mountains in south eastern turkey to the minab fault in the east of the strait of hormoz in southern iran. structurally, its formation is related to the continuing convergent movement between the arabian plate to the southwes...
