This tsunami was recorded in Chile on 01-25-1939 T03:32:14, where a sea wave released a sizeable amount of seismic energy reaching a magnitude of 8.3Mt. Tsunamis are often caused by earthquakes, and this tsunami was caused by a quake that struck at a focal depth 60km below the surface. Natural disasters can often be deadly, and this event occurred in a populated area claiming 30000 souls.
