About this tracker
New Jersey's Seismic Activity
New Jersey became the center of east coast seismology attention in April 2024 when a magnitude 4.8 earthquake struck near Tewksbury, felt by over 42 million people from Maine to Virginia. This event was followed by hundreds of aftershocks and reminded the region that intraplate earthquakes, while less frequent than their west coast counterparts, can be significant.
The Ramapo Fault, running from southeastern New York through northern New Jersey into Pennsylvania, is the primary seismic feature in the region. While it does not produce earthquakes as frequently as plate boundary faults, it is capable of magnitude 6+ events based on geological evidence. Track New Jersey seismic activity alongside global events on our earthquake tracker.
