Short description

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 3Strong 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.
