CHILE:ATACAMA

This earthquake was recorded at a focal depth of 35km below the ground in Chile on 11-11-1922 T04:32:36, where it released a sizeable amount of seismic energy and reached a magnitude of 8.7 on the richter scale. Considering this quake occurred 35km under the surface, it is best classified as a deep geologic event. Earthquake intensity was also measured using the Mercalli intensity scale which quantifies the severity of shaking felt by the quake. On a scale of 1 (barely sensed) to 12 (completely devastating), this quake had an intensity of 11. An earthquake of this magnitude would likely be causing destruction to well-built wooden structures; most masonry and frame structures with foundations would be destroyed. Expect rails to be bent, bridges detroyed, and loss of life. Quakes can often be deadly, and this event occurred in a populated area claiming 500 souls and destroying structures.

Surface Geology

Underlying geological composition for the surrounding area.

Chile Cretaceous Antucoya - porphyry copper
Cretaceous calc-alkalic plutons, including batholiths.
Chile-Peru Paleocene-Eocene Toquepala - porphyry copper
Paleocene and Eocene mostly calc-alkaline plutons. Includes the Toquepala volcanics and coeval porphyry plutons (Peru), and rhyolite domes, dacite pyroclastics, and associated calderas (Chile).
Argentina Permian San Jorge - porphyry copper
Distribution of Permian calc-alkaline generally dioritic to dacitic plutons defines two geographically separate sub-tracts, SA16aPC and SA16bPC, which are southern continuations of Permian tract SA18PC.
