Map depicting the extent of the Ramapo Fault System in New York, New Jersey, and Pennsylvania. The Ramapo Fault zone is a system of faults between the northern Appalachian Mountains and Piedmont areas to the east. [1] Spanning more than 185 miles (298 km) in New York, New Jersey, and Pennsylvania, it is perhaps
Map of the Ramapo Fault System: Earthquake epicenter at Lebanon, NJ. Hopewell Fault (red) and Flemington Fault (light blue) join the Ramapo (yellow) fault near the quake epicenter.
Map depicting the extent of the Ramapo Fault System in New York, New Jersey, and Pennsylvania. The Ramapo Fault, which marks the western boundary of the Newark rift basin, has been argued to be a major seismically active feature of this region, [22] but it is difficult to discern the extent to which the Ramapo fault (or any other specific ...
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]
In New Jersey, fault lines do not generally break the Earth's surface, but are based several miles below. A map showing the physiographic provinces in New Jersey, and the location of the Ramapo Fault.
Scientists suspect that the earthquake likely originated in the area of the Ramapo fault zone in the Newark basin. The fault system contains a branching network of faults.
Ramapo Torne in Harriman State Park, part of the Ramapo Mountains. The Ramapo Mountains are a forested chain of the Appalachian Mountains in northeastern New Jersey and southeastern New York, in the United States. They range in height from 900 to 1,200 feet (270 to 370 m) in New Jersey, and 900 to 1,400 feet (270 to 430 m) in New York.
One of those is the Ramapo Fault beneath New Jersey. About 180 million to 200 million years ago, as magma tried to press up through the giant tectonic plate called Pangea, the plate started to ...
