Just off the northern terminus of the Ramapo fault is the Indian Point Nuclear Power Plant. Despite the rarity of strong East Coast earthquakes in the United States, they do sometimes occur. To understand the damage an earthquake can cause based on its seismic magnitude, Michigan Tech University created the following list of magnitude ranges and their effects: Most of the earthquakes on the East Coast fall below a 4.0 magnitude, which is a measurement of the seismic amplitude of an earthquake and its strength – but in 1884, an earthquake registering 5.2 occurred near the Ramapo fault line, destroying chimneys in New York, while people as far south as Virginia and north to the state of Maine felt the shaker. [6] In Pennsylvania, the fault descends to an area approximately to the west of Pottstown, near the Limerick Nuclear Power Plant, before making its transverse turn west to its southern terminus near Schaefferstown. "The most dangerous fault lines are those where two tectonic plates collide.". Fault lines are reliable for predicting earthquakes or earthquake That disaster led to lengthy recriminations over lax building controls and the failure of authorities to warn residents that a quake could be imminent.
There is an earthquake every minute, according to Dr Fatahi. discern the difference between different lineaments so they can map true It runs from southeastern Missouri through northeastern Arkansas to western Tennessee, western Kentucky and southern Illinois.
[1] Spanning more than 185 miles (298 km) in New York, New Jersey, and Pennsylvania, it is perhaps the best known fault zone in the Mid-Atlantic region, and some small earthquakes have been known to occur in its vicinity. However, a lineament may on an aerial or satellite map may only be a road, While there is no definite answer, experts say the San Francisco Bay Area is long overdue for a major earthquake. folding of land to the west into mountain ranges. Some countries, including Japan, Chile, Mexico and New Zealand, lie on the 'Ring of Fire' - a horseshoe-shaped band of fault lines that circles the Pacific Basin and is prone to frequent earthquakes and volcanic eruptions. With it came a series of aftershocks. [23] Studying around 400 earthquakes over the past 300 years, the study also argued that there was an additional fault zone extending from the Ramapo Fault Zone into southwestern Connecticut. The earthquake that occurred Wednesday didn't happen near a fault line in Tennessee, for the most part, the state is free of any faults that would suggest a vulnerability to earthquakes. The Ramapo Fault forms the boundary between the Newark Basin and the Highlands, running from Haverstraw, New York to near patterns. Earthquake rates in the northeastern U.S. are 100 times lower than in California, but the earthquakes that do occur in the northeastern U.S. are typically felt over a much broader region than earthquakes of the same magnitude in the western U.S.[9] This means the area of damage from an earthquake in the northeastern U.S. could be larger than the area of damage caused by an earthquake of the same magnitude in the western U.S. [6] 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. Other events can cause earth shaking, such as blasting or a mine roof collapse, but these events are not earthquakes.
The 4.5 temblor was preceded by a smaller magnitude 2.5 quake that rocked the same area about 10 minutes before, according to The US Geological Survey.

NOTE: In Western States like California, a Fault and Fault Line The U.S. Geological Survey site shows the Ramapo seismic zone as currently being active with many mini earthquakes, usually ranging below 1 up to 4.5. Northeast [15], The fault system, part of a series of north-east striking, southeast-dipping faults, is probably inactive for the most part. Sykes (1978), Earthquakes, faults and Nuclear Power Plants in Southern New York and Northern New Jersey, Science, 200, 425–429. The world's largest exposed fault line called the Banda Detachment – recently discovered along the Ring of Fire off the coast of eastern Indonesia in the Banda Sea on the Ring of Fire – exposes a fault plane on the sea floor that covers over 23,000 square miles and runs just over 4 miles deep. Recently, public knowledge about the fault has increased, especially after the 1970s, when the fault's proximity to the Indian Point nuclear plant in New York was noted. The Northern Sangre de Cristo Fault. [10] The NYC area is far from the boundaries of the North American plate, which are in the center of the Atlantic Ocean, in the Caribbean Sea, and along the west coast of North America. A magnitude 5.5 eastern U.S. earthquake, although uncommon, can be felt as far as 500 km (300 mi) from its epicenter, and can cause damage as far away as 40 km (25 mi) from its epicenter.
"Since this is a deep earthquake very few aftershocks are expected," Dr Fatahi said. 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. [21] Magma was able to seep through linear fractures along the fault during the late Triassic and early Jurassic, producing episodic flood basalts responsible for the creation of the Watchung Mountains.[13][22]. Map of active US fault lines in the USA by USGS. New Zealand has endured more than its fair share of earthquakes. Italy sits on two fault lines, making it one of the most seismically active countries in Europe.
The Pennsylvania State Seismic Network: Seismic Activity in Pennsylvania, Michigan Tech University: Earthquake Magnitude Scale.
The fault systems are short and structurally complex, so the earthquakes are not overly large by global standards (almost always < magnitude 6.8 to 7).
