A powerful 4.8 magnitude earthquake struck New Jersey on Friday morning, sending violent tremors across the densely populated northeastern United States and causing widespread alarm in major cities including Philadelphia and New York.
The rare seismic event, which occurred at approximately 10:23 AM local time, represents one of the most significant earthquakes to hit the region in decades. The United States Geological Survey confirmed the quake's epicentre was located near Lebanon, New Jersey, at a depth of about 4.7 kilometres.
Immediate Impact and Response
The tremor caused buildings to sway violently across multiple states, prompting immediate evacuations of offices, schools, and residential buildings. Social media platforms were flooded with reports from shaken residents who experienced the unusual geological phenomenon.
Transportation networks responded cautiously, with major agencies including Amtrak and NJ Transit implementing speed restrictions on rail lines while engineers conducted urgent inspections of bridges and tunnels for potential structural damage.
Regional Aftershocks and Concerns
USGS officials have confirmed several smaller aftershocks following the initial quake, while warning residents to prepare for additional tremors that could continue for several days. "Earthquakes of this magnitude are uncommon but not unexpected in this region", stated a USGS seismologist.
While initial reports indicate minimal structural damage, the psychological impact on residents unaccustomed to seismic activity has been significant. Many described feelings of confusion and alarm as buildings swayed without warning.
Historical Context and Geological Significance
This event marks one of the strongest earthquakes to hit New Jersey in over two centuries. The region typically experiences minor seismic activity, but tremors of this intensity remain exceptionally rare along the US East Coast.
Geological experts emphasise that while East Coast earthquakes are less frequent than those on the West Coast, they can be felt across much wider areas due to the region's geological composition.
Emergency services across multiple states remain on high alert as assessments continue. Officials urge residents to remain cautious and report any structural damage to local authorities.
