Thus, earthquakes represent at least a moderate hazard to East Coast cities. Earthquakes in the greater New York City area affect most of New Jersey, the most densely populated state in the United States, as well as New York City. It is difficult to discern the extent to which the Ramapo fault itself (or any other specific mapped fault in the ...
These bends are located where they intercept a "subtle geological structure" [202] of "possible fundamental importance", [203] a NNE striking zone (line "A" on the map) of various faults (including the Tokul Creek Fault NNE of Snoqualmie) and early-Miocene (about 24 Ma) volcanic vents and intrusive bodies (plutons and batholiths) extending from ...
Seismicity in New York City area. 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.
Small tsunami risk on the East coast. The East and Gulf coasts aren’t generally at risk for earthquake-caused tsunamis because they do not have major fault lines that run under their coastal ...
These lines allow tectonic plates to move and earthquakes occur when two plates slide past each other. The Ramapo Fault System is the longest in the northeastern U.S., stretching from Pennsylvania ...
