Geologic and related effects of the Taltal earthquake, Chile, of December 28, 1966

Abstract

Surface effects of the Taltal earthquake were comparatively small, probably because of the deep focus, although the magnitude was 7 . Small fractures broke the ground surface along fault zones in the vicinity of Taltal. Minor slumping occurred on a few steep natural slopes and in some cuts and fills along highways. There was minor damage at a few open pit mines. At Taltal, the town most affected by the earthquake, 250 buildings out of a total of 1,100 were heavily damaged.
