Hidden Mountainville Fault Behind 2024 New Jersey Earthquake Uncovered

Columbia University researchers used LiDAR, aftershock locations, 3D seismic data, and lab tests to identify a previously unmapped, immature basement fault—the Mountainville Fault—about 3.5 km west of the Tewksbury epicenter. This fault better fits the 2024 Mw4.8 New Jersey quake than the Ramapo Fault and suggests a local shallow stress perturbation plus fault heterogeneity contributed to the event, indicating that immature faults could be significant earthquake sources in intraplate regions and deserve further study.

Newly Uncovered Mountainville Fault Tied to 2024 New Jersey Earthquake

A study in the Journal of Geophysical Research: Solid Earth identifies the Mountainville Fault near Tewksbury, NJ as a previously unmapped, immature basement fault that likely contributed to the April 2024 Mw4.8 quake near the Ramapo Fault. Using LiDAR topography, aftershock data, and lab friction tests, researchers tie the surface trace to a fault about 3.5 km west of the epicenter and warn that such hidden faults could pose important seismic hazards on the US East Coast, potentially triggered by local stress changes rather than Ramapo Fault slip alone.

Westchester rattled by a minor 2.3 quake, USGS confirms

A 2.3-magnitude earthquake struck Sleepy Hollow in Westchester County around 10:17 a.m., about 4.5 miles underground, felt by more than 900 people. Officials say quakes of this size are typically minor with little to no damage, and there are no expected impacts in New York City; the event is linked to the Ramapo Fault region.

"East Coast Earthquake Aftershocks: What's Next for the Region?"

The 4.8-magnitude earthquake that struck the New York City area has raised concerns about the potential for a larger seismic event in the future. Experts warn that the region is overdue for a significant earthquake, with a 20 to 40 percent chance of a 5.2 magnitude quake occurring within the next 50 years. While the recent quake caused no major damage, it has highlighted the need for better preparedness and monitoring of seismic activity in the area, particularly along the Ramapo Fault. Although it's difficult to predict when a "big one" might occur, experts emphasize the importance of gathering more data and conducting further studies to provide more accurate seismological forecasts.

"4.8 Magnitude Earthquake Shakes Northeast Cities, Impact Felt from New York City to Philadelphia"

A 4.7 or 4.8 magnitude earthquake centered near Whitehouse Station, New Jersey, rattled New York City and the surrounding area, with reports of shaking and rattling felt throughout the Tri-State Area and as far away as Baltimore. There have been no reports of damage so far, and officials are assessing the impacts. This event comes after the USGS warned of potential damaging quakes in the United States, and it's a reminder of the seismic activity in the region, including the presence of the Ramapo Fault and smaller fault lines under Manhattan.
