3.0-Magnitude Earthquake Shakes New York Region, Causes No Major Damage

Written: August 3, 2025, 21:00 (U.S. Eastern Time)

A small but noticeable earthquake struck the New York metropolitan area on Saturday night, briefly shaking buildings and prompting thousands of reports from residents across several states. The tremor, centered in northern New Jersey, did not result in injuries or significant damage.

Epicenter and Impact of the Earthquake

According to the U.S. Geological Survey (USGS), the earthquake occurred at approximately 10:18 p.m. Eastern Time on Saturday, with its epicenter located near Hasbrouck Heights, New Jersey. It registered a magnitude of 3.0 and occurred at a depth of 6.2 miles (10 kilometers) underground.

The quake was felt in northern New Jersey, southern New York, and parts of southern Connecticut. In New York City, which has over 1 million buildings, officials confirmed that no emergency calls or structural issues were reported as of Sunday morning.

More than 10,000 people submitted responses to the USGS “Did You Feel It?” survey, noting mild to moderate shaking but no significant consequences.

Earthquake Activity on the U.S. East Coast

While earthquakes are more commonly associated with the West Coast, experts note that tremors in the Northeast United States are not particularly rare.

“The northeast part of the United States does not see large earthquakes very often,” said Jessica Turner, a geophysicist at the National Earthquake Information Center, a division of the USGS.

Since 1950, the region has recorded 43 earthquakes of 3.0 magnitude or higher within a 155-mile (250-kilometer) radius of Saturday night’s event, according to USGS data.

Notably, a 4.8-magnitude quake in Tewksbury, New Jersey, in April 2024 was felt from Boston to Baltimore, temporarily impacting Amtrak services and flight schedules along the busy Northeast Corridor.

Earlier that year, in January 2024, a 1.7-magnitude quake hit the Astoria neighborhood in Queens, New York, drawing concern but causing no reported harm.

Historical Seismic Events in the Region

Although damaging earthquakes are rare in the Northeast, history records a few significant instances. According to the USGS, the New York region experienced damage from earthquakes in 1737 and 1884.

These events underscore the point that while large, destructive earthquakes are infrequent, they are not impossible. Typically, the region sees noticeable seismic activity only a few times per century.

Why Earthquakes Feel Different in the East

The East Coast’s geology contributes to how quakes are experienced. Seismologist Lucy Jones explains that the key difference between East and West Coast earthquakes lies in the underlying tectonic structures.

The San Andreas Fault in California lies at the boundary between two tectonic plates — the Pacific Plate and the North American Plate — where movement is frequent and well-mapped.

In contrast, New York lies far from any major plate boundary, situated in the middle of the North American Plate. Here, residual tectonic stress builds up and is released unpredictably. This makes it difficult for scientists to forecast earthquake behavior in the region.

“The rocks on the East Coast are particularly cold and hard and therefore do a better job of transmitting the energy,” said Jones. “That means a small earthquake in New York can be felt over a much larger area compared to one in California.”

Because of this, Saturday’s 3.0-magnitude quake was felt across a wide geographical area, even though the energy release was moderate.

Role of Fault Lines: Ramapo and Beyond

The Ramapo Fault, a well-known geological feature in the region, often comes up during seismic events in the Northeast. However, experts say there’s no clear indication that Saturday’s quake was associated with that specific fault line.

While small earthquakes have been recorded near the Ramapo Fault, geologists have found no recent evidence of large-scale activity along it.

Should Residents Expect Aftershocks or Future Quakes?

Following any seismic event, the potential for aftershocks exists. But in this case, the likelihood of another noticeable quake appears low.

“At just 3.0, the chances are there will not be another felt event,” said Jones. “Most likely is an unfelt, magnitude 1 or 2 aftershock.”

That said, seismologists emphasize that every earthquake slightly increases the chance of subsequent activity — though typically within a narrow window of time and geographic area.

Preparedness in Low-Risk Zones

While the East Coast isn’t known for frequent or powerful earthquakes, officials and experts encourage residents to remain informed and aware.

Resources such as the USGS Earthquake Hazards Program and local emergency management websites offer tools for understanding seismic risk, preparing homes, and knowing what to do during an earthquake.

Although the tremor on Saturday night caused little more than momentary surprise, it served as a reminder that the Northeastern U.S. is not immune to geological shifts — even if they occur infrequently.
