The 1984 San Pedro Basin earthquake occurred on June 24 at 07:17:14 local time with a
Tectonic setting
The northern boundary of the Caribbean Plate is a diffuse zone of varied fault types. The Muertos Trough marks the southern portion of this zone of deformation with north dipping convergence.[4]
Earthquake
This thrust earthquake occurred on a shallow and north-dipping fault and, at the time, it was the largest instrumentally recorded event in the Los Muertos Trough.[5]
Intensity
The United States Geological Survey estimated that more than 227,000 people were exposed to intensity VII (Very strong) shaking and more than 2.8 million experienced intensity VI (Strong) shaking.[3]
Aftershock
Five hours after the mainshock, a destructive 5.2 Mw aftershock occurred about 5–10 miles to the northeast. Five deaths are also attributed to this event.[6]
