On August 30, 2022 at 21:14 UTC, a magnitude 2.3 shallow crustal earthquake struck near New Jersey, at a depth of 5.0 km and coordinates 40.9223°, -74.5313°. This earthquake was detected by 24 seismic stations with good location accuracy and was assigned a USGS significance rating of 120, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 2.3 releases seismic energy equivalent to roughly 42.5 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 23 m — a useful intuition for the size of the slip patch on the fault.

The epicenter is located in New Jersey, a region characterized by the Ramapo Fault system, an ancient structure occasionally reactivated by regional tectonic stresses. The nearest mapped fault system is the Ramapo Fault. View all earthquakes in New Jersey.

Were there aftershocks?

Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 2.3 earthquakes can continue for several days and gradually diminish over time.

Has New Jersey had earthquakes this big before?

The largest recorded earthquake in New Jersey was the M4.7 Tewksbury earthquake of April 5, 2024. Today's magnitude 2.3 event is significantly smaller than that historical record.
