The Ramapo Fault zone is a system of faults between the northern Appalachian ... It is the surface location of the fault between basement blocks of Precambrian ...
The Ramapo Fault System is the longest in the northeastern U.S., stretching from Pennsylvania to southeastern New York. Map of the Ramapo Fault System: Earthquake epicenter at Lebanon, NJ.
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.
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 mapped fault in the area) might be any more of a source of future earthquakes than any other parts ...
The location is along the Ramapo Fault System, where most of New Jersey's earthquakes are concentrated. Stretching from Pennsylvania through New Jersey and into New York, this fault system is the ...
The border fault is the Ramapo Fault on the western boundary of the basin; this is where the hanging wall of the graben slid down to its current position. Estimates to the depth of accumulated sediments on the western side of the basin, and therefore the depth of the hanging wall, are in the area of 11,000 feet.
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. Some are mapped but ...
The earthquake is thought to have originated from within the New Jersey Highlands of the Reading Prong, [4] possibly on the 300 km long, 12 km wide Ramapo Fault zone, a structure formed during the Late Triassic during the break-up of Pangaea. [6] The mainshock was part of a sequence that occurred over a span of several hours. [4]
