A damaging earthquake affecting New York City in 1884 was incorrectly argued to be caused by the Ramapo fault, likely because it is the most prominent mapped fault in the greater New York City area. At the present, the relationship between faults and earthquakes in the New York City area is understood to be more complex than any simple ...
Data from U.S. Geological Survey (Top, USGS) and National Earthquake Information Center (Bottom, NEIC). In top figure, closed red circles show 1924–2006 epicenters. Open black circles show larger earthquakes of 1737, 1783 and 1884. Green lines are the Ramapo fault. Seismicity of the New York City area is relatively low. [1]
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.
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]
The Ramapo Fault today produces relatively small quakes, and the last period of major seismic activity was around 200 million years ago, experts estimate. New York City has its own share of faults ...
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.
