Studies made between Arauco and Valdivia with respect to the earthquakes of 21 and 22 May 1960

Abstract

ABSTRACT The earthquake of 21 May was felt as a brusque horizontal movement; the large shock of 22 May was felt as a suave movement of large amplitude similar to a ship at sea. Lebu was extensively damaged. The shoreline at Lebu was elevated 1.5 meters, rendering docks and waterside facilities useless; a large expanse of new beach was exposed. Rio Lebu is no longer navigable because of the uplift. Details of tsunami are reported for several towns on the Arauco Peninsula and south to Tolten.
