Time-Dependent Probabilistic Seismic Hazard Analysis Using the Simulated Records, the Case of Tehran

Common attenuation equations are developed by seismic records which belong to earthquakes that have happened so far. Although there are many recorded data during last 50 years, it is not possible to consider all possible wave propagation paths, site types and fault rupture mechanisms inclassical att...
