Iranian Strong Motion Database: 2004-2014 - a Processing and Preliminary Analysis

Abstract eng:
The Iranian strong motions are recorded in the last 42 years in the national strong motion network of Iran. There are actually more than 11,800 of 3 component accelerograms recorded in this network. In this study, we employ the strong motion records, which are recorded by Iran Strong Motion Network (ISMN), established by the Building and Housing Research Center (BHRC) of Iran. In the last years (2004-2014) there are important earthquakes recorded in this network (among which the greatest Iranian earthquake in the last 50 years, which was the 16 April 2013 M w 7.8 Saravan, Makran SE Iran earthquake; occurred in the subduction zone of Makran). More than 6200 three component accelerograms have been recorded in this 11 years period of time, of which 100 records having greater peak acceleration have been processed with a more focus in this study. In this respect, the data selected are processed in order to achieve the most important strong motion parameters in aspect of engineering seismology and carrying out a preliminary analysis of the available data.
