The Ramapo Fault forms the western boundary of the Newark Basin. It is the surface location of the fault between basement blocks of Precambrian bedrock shown in orange. New Jersey, eastern Pennsylvania, and southeastern New York are divided geologically into four physiographic provinces, each distinctive in their
These rocks lie north of the Furlong fault which is an offshoot of the larger Chalfont fault. [11] Buckingham Mountain rises south of the valley and comprises quartzite. The other ridge is less prominent and is underlain by the conglomerates of the Stockton Formation. Karst is a localized problem in this area.

The causative fault for the earthquake was likely in the area of the Ramapo Fault zone, [8] which extends from Pennsylvania to New York [9] and was formed by the break-up of the supercontinent Pangaea during the Late Triassic. [10] Another possible origin is the Flemington Fault, a younger fault in the same area. [11]
