... earthquakes are crustal earthquakes, and in regions far from the collision zone between the Arabian-Central Iranian plates and the Makran subduction zone, intra-plate feature of earthquakes predominate ( Abbassi 2009 ). The present study calculated the stress drop for the southeast of Tehran to be about 33...

Although an emergency response plan for the first 72 h after an earthquake was prepared by the Japanese firm for Tehran (JICA, 2009), vulnerable structures of the old city have not yet been retrofitted, evacuated, or rebuilt. Disaster management is poor, emergency-response preparation and facilities...

... result, we include some large earthquakes from Iran, Italy, and Japan with magnitude larger than 5.9. Although the optimal trend is finally obtained by fitting a line to the distance‐averaged points, we conclude that the same trend and relationship as Japan can be used in Tehran early warning system. We...
