The Ramapo Fault

  • In a rare occurrence, New York City experienced a 4.8 magnitude earthquake.
  • The Ramapo Fault in the Appalachian Mountains near New Jersey is being investigated as a possible cause of this earthquake. 

About the Ramapo Fault

  • Fault lines are fissures in the Earth’s crust that allow tectonic plates to move and so cause earthquakes.
  • The Ramapo Fault is the result of tectonic activity caused by the breakup of the supercontinent Pangaea during the Mesozoic Era.
  • It is largely a right-lateral strike-slip fault caused by horizontal movement along the fault line as the North American and Eurasian plates move together.
  • While the Ramapo Fault is not as seismically active as other faults in the region, it has previously generated earthquakes and is still a potential source of seismic risks.

Geographical Distribution:

  • The fault spans three northeastern states, including Pennsylvania, New Jersey, and New York.
  • The fault runs across a variety of geographical features, including rift valleys, hills, and ridges, highlighting the region’s rich geological history.
  • It crosses with the Appalachian Mountains, altering the surrounding landscape.
