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.
The Laurentide Ice Sheet, which covered Canada and what is currently the New England landscape, was a massive sheet of ice and the primary feature of the Pleistocene epoch in North America. Geologists are currently working on calculating the thinning of the Laurentide Ice Sheet, which can improve the accuracy in de-glacial paleoclimate models ...
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.
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 geology of North America is a subject of regional geology and covers the North American continent, the third-largest in the world. Geologic units and processes are investigated on a large scale to reach a ...
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 ...
A 1638 engraving depicting the Mystic massacre An English map of New England c. 1670 depicts the area around modern Portsmouth, New Hampshire. Relationships alternated between peace and armed skirmishes between colonists and local Native American tribes, the bloodiest of which was the Pequot War in 1637 which resulted in the Mystic massacre.
