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 is the longest fault in the northeast, but scientists dispute how active this roughly two-hundred-million-year-old fault is. Many earthquakes in the state's varied seismic history are believed to have occurred on or near it. The fault line is visible at ground level and likely extends as deep as nine miles below the surface. [93]
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 ...
One of those is the Ramapo Fault beneath New Jersey. ... The fault runs for about 185 miles from New York, through New Jersey — beneath Passaic, Morris, Somerset and Hunterdon counties — and ...
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.
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.
