N.B.: The magnitude for this earthquake has been recalculated since the following articles were written. Magnitude 9.5 is a better determination of the size of this earthquake.
More than 2,000 killed, 3,000 injured, 2,000,000 homeless, and $550 million damage in southern Chile;tsunami caused 61 deaths, $75 million damage in Hawaii; 138 deaths and $50 million damge in Japan; 32 dead and missing in the Phillippines; and $500,000 damage to the west coast of the United States.

Near coast of Chile. Magnitude 8.3. More than 2,000killed, 3,000 injured and $550 million damage in Chile; seismic sea wave caused 56 deaths, $75 million damage in Hawaii; 138 deaths and $50 million damage in Japan; $500 thousand damage to west coast of the United States.
From ISC Bulletin, The International Seismological Summary.
The following table lists particulars reported by the Survey for the larger shocks of the series of destructiveearthquakes in central and southern Chile which began on May 21 and which is still continuing as of this writing in mid-August. The first large shock of the series, on May 21, 1960 at 10h02m50s, caused many casualties and extensive property damage at Concepcion and surrounding area. The ensuing series of earthquakes and accompanying seismic sea waves caused many casualties and extensive property damagealong the central Chile coast between latitudes 36 deg S and 44 deg S. Late press reports estimate that the casualties range from 6,000 to 10,000 persons dead or missing. The main shock (May 22, 1960, 19h11m20s GCT) set up a series of seismic sea waves that not only was destructive along the coast of Chile, but which also caused numerous casualties and extensive property damage in Hawaii and Japan,and which was noticeable along shorelines throughout the Pacific Ocean area. The Chilean government estimated 2,000,000 people homeless and $3000,000,000 property damage as a result of the earthquakes. Destruction was heaviest in the cities of Concepcion, Valdivia, and Puerto Montt, and many smaller towns and villages were virtually demolished. Massive landslides, violent volcanic eruptions andextensive dislocations of the land surface were reported in early press reports from Chile."
From Seismological Notes (BSSA). "Seismological Notes" is a list of recent important earthquakes with short summaries included in each issue of the BSSA.
Beginning on 21 May 1960, southern Chile was ravaged by a series of earthquakes whose foci lie within a band 1,300 km long, between latitudes 37deg and 48deg S. The epicentres follow the main SSW.-NNE. feature, continental in the north, submarine in the south, separating a region which has risen (coast of Lebu) from a vast region which has subsided.
The official death roll rose to 660 dead and 717 missing, numbers much lower than those first announced in the press; 58,622 houses were completely destroyed (Tazieff, 1962). Damage was put at $550million.
