This earthquake was recorded at a focal depth of 82km below the ground in Chile on 11-30-1976 T00:40:57, where it released a sizeable amount of seismic energy and reached a magnitude of 7.3 on the richter scale. Considering this quake occurred 82km under the surface, it is best classified as a deep geologic event. 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 8. An earthquake of this magnitude would likely be causing considerable damage to specially designed structures; well-designed frame structures thrown out of plumb. Damage would be great in substantial buildings, with partial collapse. Expect that buildings would be shifted off foundations. Quakes can often be deadly, and this event occurred in a populated area claiming 1 souls and destroying structures.
