The 1956 Chim earthquake was a destructive multiple-shock event that occurred on March 16 in Lebanon along a strand of the Dead Sea Transform (DST) fault system.

[1] The epicenter was located in the south of Lebanon in the Chouf District.

[2] The DST is a 1,609 km (1,000 mi) long transform fault that runs in a mostly north–south direction from the northern end of the Red Sea along the Jordan Rift Valley to the Taurus Mountains complex in southern Turkey.

[4] The Roum fault runs for a length of 35 kilometers (22 mi) between the Hula basin the Awali river and is the westernmost strand of the fault system in that area.

A paleoseismic trench investigation revealed that it may have been the source of the twin-shock event.
