Iranian Strong Motion Network

Road, Housing and Urban Development Research Center (BHRC), is operating a network of about 1074 digital strong motion accelerometer. About nearly 11,000 three component strong motions have been recorded from 1973 in earthquakes between 3<Mw<7.8.
Strong motion monitoring of earthquake activity in Iran began at the early of the 1973 with 270 analog SMA-1 stations. In the early 1990s, after Manjil
destructive earthquake, the National Strong Motion Network was renewed by digital devices, SSA-2. This network, consisting of 1070 SSA-2 sensors, was installed across Iran, 547 free-field stations as well as of 65 dam-related.The modern Iran Strong Motion Network was established in the 2007, by 65 Guralp sensors using 24-bit digitizer. This new network is installed in Tehran and some other major cities in Iran as a real-time system.

道路、住房与城市发展研究中心（BHRC）目前运维着一套包含约1074台数字强震仪（digital strong motion accelerometer）的监测网络。自1973年起，该网络已记录到震级满足3<Mw<7.8的地震事件所产生的近11000组三分量强震动记录（three component strong motions）。
伊朗的地震强震动监测工作始于1973年初，当时部署了270台模拟式SMA-1型强震仪。20世纪90年代初，曼吉勒（Manjil）破坏性地震发生后，伊朗国家强震动监测网络被升级为采用SSA-2型数字设备的新网络：该网络共部署1070台SSA-2型传感器，覆盖伊朗全境，其中包含547个自由场台站（free-field stations）与65个大坝相关台站。
2007年，伊朗建成现代化国家强震动监测网络，该网络配备65台搭载24位数字化仪（24-bit digitizer）的古洛普传感器（Guralp sensors），作为实时监测系统部署于德黑兰及伊朗其他主要城市。
