Magnitude: 7.3M
Time: 10-04-1940 T07:54:42
Country: CHILE

CHILE:NORTHERN

This earthquake was recorded at a focal depth of 75km below the ground in Chile on 10-04-1940 T07:54:42, where it released a sizeable amount of seismic energy and reached a magnitude of 7.3 on the richter scale. Considering this quake occurred 75km under the surface, it is best classified as a deep geologic event. 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.
