Map depicting the extent of the Ramapo Fault System in New York, New Jersey, and Pennsylvania ... Flemington-Furlong, and Chalfont faults, are present within the ...
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 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 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 ...
On April 5, 2024, at 10:23 EDT (14:23 UTC), a M w 4.8 earthquake occurred in the U.S. state of New Jersey, with the epicenter in Tewksbury Township.While it was felt across the New York metropolitan area, Delaware Valley, the Washington D.C metropolitan area, and other parts of the northeastern United States between Virginia and Maine, it had a relatively minor impact, with no major damage ...
To map the subduction zone, researchers at sea performed active source seismic imaging, a technique that sends sound to the ocean floor and then processes the echoes that return. The method is ...
First, the overlap marks one of the only locations in the Newark Basin where an intrusion successfully crossed the Ramapo fault and effectively spilled over the western edge of the basin. Second, the trap rock comprising the intrusion at this location is fine grained and unlike the dense, coarse diabase common to Cushetunk Mountain. [ 12 ]
A map by the California Geological Survey shows faults near the Lake Almanor area in Plumas County, where a magnitude 5.5 earthquake struck Thursday, May 11, 2023, followed by a magnitude 5.2 ...
