When was the last NJ earthquake? · Ramapo Fault and NJ fault zones · Felt reports across northern New Jersey. These events shaped modern earthquake preparedness — from building codes and early warning systems to tsunami evacuation routes — across the region.
Fault systems
Runs from southeastern New York through northern New Jersey into Pennsylvania. An ancient Mesozoic rift-margin fault with occasional modern M4-5 activity. The longest and most seismically active fault in the NJ region; M6 is considered plausible though no historical M6+ event is documented.
Learn moreEast-west oriented fault that bounds the Triassic-age Newark sedimentary basin. Largely inactive in the modern seismic record but geologically recent in the larger timescale. M5.5 is considered plausible based on fault dimensions.
Learn moreBounds Lake Hopatcong and the northern NJ Highlands. The 1957 Lake Hopatcong M4.0 earthquake is a candidate event on this structure. Part of the broader northern NJ fault network in the Highlands physiographic province.
Learn moreRamapo Fault System — the 300km Appalachian-era normal fault · Newark Basin Border Fault — the Mesozoic rift feature · Hopatcong Border Fault and northern NJ geology. Understanding the dominant fault systems in the region is the foundation of earthquake preparedness — every safety protocol, building code, and early warning system is calibrated against these geologies.

About this tracker
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.
Frequently Asked Questions
Check the live seismic map above for the latest earthquake activity in New Jersey. Our tracker shows all detected seismic events in near real-time, including small events that may not be widely reported.
The Ramapo Fault is the most significant fault system in New Jersey, running from southeastern New York through northern New Jersey into Pennsylvania. It has been associated with periodic small earthquakes and is capable of producing larger events.
