My Dream of Subsidence & Earthquakes
HISTORY OF EL PASO EARTHQUAKES:  The Franklin Mountains continue to rise while the Hueco Bolson sinks. On average, an earthquake in the 3.0 to 4.0 magnitude occurs in El Paso every 10 years. The last such quake occurred on December 8, 1972 (magnitude of 3.0) near the Texas-New Mexico border in Northeast El Paso. Geological evidence seems to show that a major quake occurs along the Franklin Mountains every 5000 years or so.
