对伊朗强震记录进行了研究和校正，以便为地震危险性评估等进一步研究建立可靠的数据库。伊朗强震台网于1974年安装，目前由BHRC监督下的1000个台站组成。这些仪器是SMA-1模拟型（在万日地震前安装）和SSA-2数字运动学型（在万日地震后安装）。在总共450条具有先验满意质量的记录（在SMA-1记录的情况下记录良好并正确数字化）中，选择了279条记录，可以将正确确定的震源参数（震源震级和震中距离）联系起来：169条记录对应于SMA-1仪器，其余110条记录对应于地震构造区域；扎格罗斯143人，伊朗中部/卢特78人，阿尔博尔兹48人，阿扎尔巴扬9人，科佩-达格地区1人。本文的主要成果是提供了伊朗的第一个强震目录，并指出了场址条件；记录可靠的频带，加速度，速度和位移的峰值，震源参数（震级，震中和大地震距离），强度，最后是断层平面解。
The Iranian strong motion records are studied and corrected in order to develop a reliable data base for further studies such as seismic hazard assessment. The Iranian strong motion network was installed in 1974, and now comprises 1000 stations under the supervision of BHRC. This instruments are SMA-1 analog (installed before the Manjil Earthquake) and SSA-2 digital kinemetrics types (after Manjil Earthquake). Out of a total of 450 records with a priori satisfactory quality (well recorded and correctly digitized in the case of the SMA-1 records), a set of 279 records was selected for which it was possible to associate correctly determined source parameters (source magnitudes and epicentral distances): 169 correspond to SMA-1 instruments, and the remaining 110 to seismotectonics regions are; 143 in Zagros, 78 in Central-Iran / lut, 48 in Alborz, 9 in Azarbayjan and one record in the Kopeh-Dagh region. The main outcome of this paper is to provide the first strong motion catalogue of Iran, with the indication of the site conditions;the frequency band over which the records are reliable, the peak values of acceleration, velocity and displacements,the source parameters (magnitudes, epicentral and macroseismic distances), the intensity and finally the fault plane solutions whenever possible.
