Magnitude 4.8 earthquake hits Delaware on the East Coast



A magnitude 4.8 earthquake struck Friday morning about 3.1 miles northeast of Lebanon, New Jersey. Residents in New Jersey and Delaware, as well as further up and down the East Coast, felt the quake.

The tremor only lasted a few seconds, but many took to social media to ask if it was an earthquake they had felt. The US Geological Survey confirmed shortly afterwards that the quake had occurred at 10:23 a.m

According to the Richter scale, which is used to measure earthquake strength, this is a “mild” earthquake. Still geological survey posted on X that it was “remarkable.”

According to the US Geological Survey website, residents in Washington DC, Pennsylvania, New York, Connecticut, Rhode Island and Massachusetts also reported feeling the earthquake.

“I’m still shocked about this,” one person posted on X.

The Richter scale measures earthquakes on a scale of 1 to 10, with 10 being the strongest and 1 being the weakest. The weakest occur daily, while a magnitude 10 earthquake is considered a “superquake.”

In practice, an earthquake with a magnitude greater than 9.5 has never been recorded. This happened in Chile in 1960.

Does this happen often?

The US Geological Survey released Friday morning

This is a zone that one study has called a “passive-aggressive margin” because “there is no active plate boundary between the Atlantic and North American plates, but there are tensions.”

Friday's quake came days after a magnitude 7.2 quake struck Taiwan, killing at least 10 people and injuring more than 1,000.

It is not yet clear whether anyone was injured in Friday's quake in New Jersey.

Delaware State Police Posted on X Shortly after reports surfaced, he was aware of “several reports of seismic activity in northern Delaware.”

The post continued in all caps: “UNLESS YOU REPORT AN EMERGENCY, PLEASE DO NOT CALL 911.”
