This earthquake was recorded in Chile on 10-09-1831, where it released a sizeable amount of seismic energy and reached a magnitude of 7.8 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 7. 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.
