Pedro Miguel Fault

The Pedro Miguel Fault is a seismic fault that runs beneath the Panama Canal and near Panama City, home to approximately 1.2 million of Panama's approximately 3.3 million inhabitants.[1]

Seismic activity

Both faults are active, cause earthquakes every 600 to 900 years, and could cause ground slippage of up to 9.8 feet (3.0 m).[2] An earthquake in 1882 caused a regional tsunami.[1] A team of seismologists led by Tom Rockwell of San Diego State University found evidence suggesting both faults slipped simultaneously around 700 CE.[1][2]

Potential consequences of an earthquake

The Pedro Miguel and the Limón Fault system are a concern for geologists, as a strong earthquake centered on either could damage the canal, drain the lake that supplies water for the operation of its locks, Lago Gatun, and cause severe damage in the capital.[1][2]
