StructureReg.Struct: Underlying Miocene Volcanics Are Cut By Normal Faults With Displacements Of 50-100 M Into A Series Of E Tilted Blocks Upon Which Post-Miocene Sediments And Tuffs Were Deposited (With Initial Dips). Section Was Later (Pliocene To Recent) Cut By En-Echelon Normal Faults Striking N 10-45 W And Dipping 65-70 Sw And Ne. Major Faults Inclined Towards The Sw, With Maximum Vertical Displacement Of 250 M (Sta. Agueda Fault). Most Faults Show Less Than 80 M Of Displacement.
