History

Historical Context

On May 22 1960 the Valdivia megathrust struck Chile with a magnitude 9.5, the strongest quake ever recorded and generating tsunamis up to 25 m that reached Hawaii. The disaster spurred global seismic cooperation, a pattern echoed by later events such as the 1964 Good Friday quake in Alaska and subsequent deep-focus tremors in the Andes, which reinforced regional monitoring and preparedness.
