SE.ALASKA,AK

This tsunami was recorded in Usa on 07-10-1958 T06:15:59.9, where a 524.6 meter tall sea wave released a sizeable amount of seismic energy reaching a magnitude of 7.8Mt. Tsunamis are often caused by earthquakes, and this tsunami was caused by a quake that struck at a focal depth 35km below the surface. Natural disasters can often be deadly, and this event occurred in a populated area claiming 5 souls. Reports suggest the total cost of damages reached $.1 million as structures were reduced to rubble. The USGS monitors tsunami events around the globe, and has assigned this event an ID of 1880. This region of Usa falls within region code 87.
