This earthquake was recorded at a focal depth of 60km below the ground in Mexico on 12-12-1902, where it released a sizeable amount of seismic energy and reached a magnitude of 7.8 on the richter scale. Considering this quake occurred 60km under the surface, it is best classified as a deep geologic event. 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.
