Short summary
This paper develops a seismic hazard methodology for crustal faults without direct evidence of present activity. The knowledge of this fault type is important when faults are located closer than 10 km from a highly populated area. The San Ramón Fault, close to Santiago, the capital of Chile, was chosen to test this methodology. The main result is the identification of some areas (close to the fault) where damage would be severe if the expected earthquake occurs.
