This earthquake was recorded in Iran on 12-22-0856, where it released a sizeable amount of seismic energy and reached a magnitude of 7.9 on the richter scale. Earthquake intensity was also measured using the Mercalli intensity scale which quantifies the severity of shaking felt by the quake. On a scale of 1 (barely sensed) to 12 (completely devastating), this quake had an intensity of 10. An earthquake of this magnitude would likely be causing destruction to well-built wooden structures; most masonry and frame structures with foundations would be destroyed. Expect rails to be bent, bridges detroyed, and loss of life. Quakes can often be deadly, and this event occurred in a populated area claiming 200000 souls and destroying structures.
