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 ...
Connecticut's Eastern border fault was formed, a fault which begins in New Haven and stretches 130 miles up to Keene, New Hampshire. As a result, the land west of this fault was downset, resulting in a rift valley and causing the land to tilt an average of 15 to 25 degrees. The fault is currently inactive.
New England is a region in the North Eastern United States consisting of the states Rhode Island, Connecticut, Massachusetts, New Hampshire, Vermont, and Maine.Most of New England consists geologically of volcanic island arcs that accreted onto the eastern edge of the Laurentian Craton in prehistoric times.
What are the fault lines under New York and New Jersey? Fault lines are fractures between blocks of rock in the Earth’s crust, the layer closest to the surface. These lines allow tectonic plates ...
The Atlantic Seaboard Fall Line, or Fall Zone, is a 900-mile (1,400 km) escarpment where the Piedmont and Atlantic coastal plain meet in the eastern United States. [2] Much of the Atlantic Seaboard fall line passes through areas where no evidence of faulting is present.
During the Permian, North America shifted north of the equator while Maine experienced uplift and erosion, exposing deeper rocks. The breakup of Pangaea during the early Mesozoic was marked with new faulting of bedrock in Maine and the intrusion of basalt dikes on southwest coast of Maine. Limited igneous activity continued into the late Mesozoic.

Scientists have yet to pinpoint the fault that ruptured in New Jersey on April 5 and rattled much of the Northeast. Now, U.S. Geological Survey researchers are in the process of installing new ...
