Parts of New Jersey and the surrounding tri-state area were rattled by two earthquakes recently – a 3.0 and 2.7 magnitude, respectively. But despite the back-to-back seismic activity, experts say Garden State residents have little to worry about.
Seismologists say that rather than being a sign of more earthquakes to come, the tremors are little more than reminders that New Jersey does, in fact, experience earthquakes.
According to experts, felt earthquakes typically occur in New Jersey every two to three years, though most go unnoticed by the general public.
Recent tremors, while stronger than average for the region, was still well below levels considered dangerous. Earthquakes under magnitude 4.0 rarely cause structural damage.
The fault lines from which the two most recent quakes are unknown, scientists said. That uncertainty is nothing new in the Northeast, where seismic activity is sporadic but not unheard of. In fact, a 4.8 magnitude earthquake in April 2024 — one of the largest in New Jersey’s recorded history — led to the discovery of the previously unknown Mountainview Fault. That quake was felt by over 42 million people from Virginia to Maine.
Geophysicist Oliver Boyd of the U.S. Geological Survey explained, saying that in the Northeast, “pretty much just about every earthquake, we discover a new fault line.”
For now, experts say there’s no evidence of a larger seismic event on the horizon, but the recent activity may prompt further geological research, and perhaps even the identification of yet another hidden fault line beneath the Garden State.
