Iran is situated in a highly seismic part of the world and has been frequently struck by catastrophic earthquakes during her recorded history. Any study of earthquakes and earthquake engineering is based on accurate knowledge of the motions of the ground during important earthquakes. To obtain such data and information a network of strong motion accelerographs is maintained by the BHRC from 1973. The network consists of more than 1100 accelerographs. In the second half of the year 2006, 130 accelerograms (with PGA greater than of O.Olg) were recorded by 90 accelerographs, which were triggered by 99 earthquakes with different magnitude. In this period the Nov, 5th koloor earthquake at Ardebil provinc was the strongest event which triggered 6 accelerographs with PGA greater than 200 em/sis at koloor station. In this article the most important earthquakes and those with more than three or more accelerograms in the studied time period are discussed in brief and the detailed information is presented in Table 1.
