This earthquake was recorded at a focal depth of 36km below the ground in Usa on 02-04-1965 T05:01:21, where it released a sizeable amount of seismic energy and reached a magnitude of 8.7 on the richter scale. Considering this quake occurred 36km 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 6. 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.
