Less than a week after a 4.8-magnitude earthquake shook the tri-state area, a 2.6-magnitude aftershock was felt in New Jersey. The occurrence, though milder, adds to the series of seismic events that have unsettled the region.
Aftershock Details:
The aftershock, which registered a 2.6 magnitude, occurred at approximately 10:22 a.m. According to the U.S. Geological Survey (USGS), it was centered about 3.1 miles southwest of Gladstone in Somerset County.
Despite its relatively low intensity, a “weak” shaking was felt across northern New Jersey, Long Island, and Connecticut.
Frequency and Depth:
This latest aftershock, measuring three miles deep, marks one in a sequence of over 40 aftershocks since the initial earthquake on Friday. Most aftershocks have been minor, with magnitudes of 2.0 or less.
Duration of Aftershocks:
Experts warn that the area may continue to experience aftershocks for some time. Typically, aftershocks persist for at least a week following the main earthquake.
The USGS estimates a 21% probability of a magnitude 3.0 or higher aftershock within the first month, with a 3% chance of a magnitude 4.0 or higher.
Understanding Aftershocks:
Aftershocks are fewer earthquakes that occur in the vicinity following a more significant seismic event, known as the mainshock.
They can persist for days to years, contributing to ongoing seismic activity in the affected area.
