A 3.0-magnitude earthquake recently shook the East Coast, specifically near Hasbrouck Heights, New Jersey, which is approximately 10 miles from downtown Manhattan. The quake occurred at 10:18 P.M. local time at a depth of around six miles. Fortunately, there were no reports of significant damage or injuries in New York City or Bergen County, where Hasbrouck Heights is situated.
This seismic event comes just a year and a half after a more powerful 4.8-magnitude earthquake rattled New York City and its surroundings in April 2024. According to the U.S. Geological Survey (USGS), earthquakes that are strong enough to be felt are not common in the eastern United States. Benjamin Fernando, a seismologist at Johns Hopkins University, mentioned in an interview with Scientific American in 2024 that this region is relatively quiet in terms of seismic activity.
While the recent 3.0-magnitude earthquake may have caused some alarm, it is essential to note that smaller earthquakes with magnitudes of 2.5 or lower are quite common in this area. The earthquake magnitude scale is logarithmic, meaning that each whole number increase in magnitude represents a tenfold increase in the size of the seismic waves produced. Therefore, the 2024 earthquake was significantly larger, being 63 times more powerful than the August 2 event.
The USGS stated that the August 2 earthquake was caused by faulting at shallow depths in the crust and did not occur near a plate boundary. Despite the region having many faults, these fractures are ancient, dating back to the time when the Appalachian and Blue Ridge Mountains were formed hundreds of millions of years ago.
Unlike the West Coast, where large earthquakes are more common, the East Coast experiences less seismic activity. However, the impact of an East Coast earthquake is felt more widely due to the efficient transfer of seismic energy through the hard bedrock of the region.
If you experienced the recent earthquake, you can share your observations with the USGS to contribute to their research and monitoring efforts. Stay informed and prepared for any future seismic events by staying updated on earthquake safety measures and guidelines.
