Though you might not have felt it, an earthquake hit South Jersey this morning.
The United States Geological Survey reported a magnitude 1.6 earthquake occurred at 12:28 a.m. Thursday near the Leisuretown section of Southampton Township in Burlington County.
The low-intensity “microearthquake” was at a depth of 7.5 miles, according to the USGS.
Earthquakes below 2.0 in magnitude are rarely felt beyond their 5-mile epicenter, according to experts.
They cause little or no damage to property and are often referred to as silent or aseismic.
There are around 900,000 earthquakes with magnitudes below 2.5 each year, according to Michigan Technical University.
In 2006, Standford University published a report stating these tiny earthquakes could be a precursor to larger, more destructive events.
The last tremor felt in New Jersey occurred Nov. 30 and was centered in Delaware.
That quake measured 4.1 on the Richter scale and was felt by residents in central and southern New Jersey, New York City and as far south as Virginia.
In 2011, a 5.8 magnitude earthquake was felt in New Jersey. That one caused millions of dollars of structural damage to buildings in Washington, D.C., Maryland and in Virginia, where it was centered.
