A newly found fault line with a rare slanted angle shows why an earthquake rattled New York City in April harder than its epicenter in New Jersey — and may be a bigger seismic activity threat ...
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 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] New York is less seismically active than California because it is far from any plate boundaries.
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 ...
The fault that ruptured beneath New Jersey on Friday morning was likely an ancient, sleeping seam in the Earth, awakened by geologic forces in a region where earthquakes are rare and seismic risks ...
The Dyckman Street Fault is a seismologically active fault in New York City which runs parallel along the southern border of Inwood Hill Park, crossing the Harlem River and into Morris Heights. [ 1 ] As recently as 1989, activity of this fault caused a magnitude 2 earthquake .
Officials in New York City say a 1.7 magnitude earthquake shook parts of Queens and Roosevelt Island on Tuesday morning, not an explosion.. Around 5:45am, the FDNY received reports of buildings ...
The New York State Thruway has a rock cut at Batavia which clearly shows the fault and is a popular point for geology class field trips. [5] The fault , which runs from Attica, New York northward to Lake Ontario, is still active and periodically causes minor earthquakes in the area.
