A magnitude 7.7 earthquake occurred in the Gilan Province between the towns of Rudbar and Manjil in northern Iran on Thursday, June 21, 1990 (June 20 at 21:00 GMT). The event, the largest ever to be recorded in that part of the Caspian Sea region, may have been composed of two or more closely-spaced earthquakes occurring in rapid succession. These quakes, exceptionally close to the surface for this region, were also unusually destructive.
