CHILE:ANTOFAGASTA

This earthquake was recorded at a focal depth of 100km below the ground in Chile on 12-26-1948 T07:12:21, where it released a sizeable amount of seismic energy and reached a magnitude of 7.0 on the richter scale. Considering this quake occurred 100km 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 7. An earthquake of this magnitude would likely be causing considerable damage to specially designed structures; well-designed frame structures thrown out of plumb. Damage would be great in substantial buildings, with partial collapse. Expect that buildings would be shifted off foundations.

Surface Geology

Underlying geological composition for the surrounding area.

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).
Chile Permian El Loa - porphyry copper
Permian calc-alkaline plutons. Tract is a northern continuation of tract SA16a,bPC and its location coincides largely with that of giant tract SA10a,bPC.
Chile Eocene–Oligocene Chuquicamata - porphyry copper
Eocene to Oligocene mainly calc-alkaline plutons, including epizonal plutons intruding volcanic-arc lava flows and breccias; equivalent to rocks in tracts SA09PC and SA12PC.
