1780年伊朗大不里士地震

The 1780 earthquake that struck Tabriz in northwestern Iran had magnitude 7.7 and is associated with about 50,000 deaths, reaching Mercalli intensity IX. The shock lay on the Iranian plateau, within the active faulting produced by Arabia's convergence with Eurasia. Tabriz, a major commercial and cultural center on the routes between Anatolia and Central Asia, was heavily damaged and rebuilt, as it had been after earlier catastrophes and would be again. The recurrence of destructive earthquakes at the city across the centuries makes it one of the most seismically significant locations in Iranian history.
