A 2.4-magnitude earthquake struck near Paramus, New Jersey, on Friday afternoon, the U.S. Geological Survey (USGS) confirmed. Recorded at approximately 1 p.m., the earthquake originated at a depth of 7.7 kilometers (4.7 miles) beneath the surface.
According to the USGS, over 230 residents reported experiencing “light shaking” in the area as of 2 p.m. This tremor comes months after a more significant seismic event earlier in the year that raised questions about the region’s earthquake risks.
Recap of the April 2024 Earthquake
On April 5, 2024, Northern New Jersey and surrounding areas were rocked by a 4.8-magnitude earthquake that sent shockwaves felt as far as New York City, Boston, Philadelphia, and even Virginia and Maine. The tremor, the largest in the area since a 5.2-magnitude earthquake hit near Brooklyn in 1884, reportedly affected 42 million people across multiple states.
Despite its magnitude, the April earthquake caused only minor structural damage near its epicenter in Tewksbury, New Jersey. However, researchers from an October report noted the event’s “peculiar behavior,” which has left experts grappling with the region’s seismic unpredictability.
Concerns About Unusual Seismic Patterns
The April earthquake exhibited unexpected characteristics, shaking New York City with unusual intensity and transmitting vibrations much farther than anticipated. “The shaking extended to regions as distant as Virginia and Maine, far beyond what our current models would predict,” the report explained.
Seismic experts have expressed concern about the implications of these findings. While significant damage was avoided, the earthquake’s uncharacteristic behavior has prompted renewed scrutiny of regional seismic risks.
“Earthquakes of this magnitude should typically cause more substantial damage near their epicenter, but that didn’t occur here,” researchers noted. They have since called for further investigations to understand whether the region is at greater risk of future seismic events than previously believed.
Preparing for the Unexpected
Friday’s minor earthquake in Paramus adds to ongoing discussions about seismic activity in the northeastern United States, a region historically considered low-risk for major earthquakes. However, the April event and its unusual effects have challenged these assumptions, urging local governments and residents to reconsider preparedness plans.
While Friday’s quake caused no reported damage or injuries, experts emphasize the importance of awareness and preparedness, especially given the surprising reach of the April tremor.
Authorities and researchers are urging communities across New Jersey and neighboring states to remain vigilant, as even minor quakes serve as reminders of the area’s latent seismic potential.
Looking Ahead
The USGS and other organizations continue to monitor seismic activity in the region closely. In light of recent events, researchers are revisiting predictive models to better understand the nature of earthquakes in the northeastern United States.
For residents of Paramus and beyond, these tremors, no matter how small, underscore the importance of staying informed and prepared for the possibility of future seismic events.
