We talked with Professor Folarin Kolawole with the Dept. OF Earth and Environmental Sciences at Columbia University about yesterday earthquake and what exactly happened.
Less than a week after a 4.8-magnitude earthquake rattled the tri-state, a 2.6-magnitude aftershock was felt Wednesday in New Jersey.
The aftershock occurred around 10:22 a.m. and was located about 3.1 miles southwest of Gladstone in Somerset County, according to the U.S. Geological Survey
The USGS said a "weak'" shaking was measured across northern New Jersey and into Long Island and Connecticut.
The latest aftershock was about three miles deep.
Wednesday's aftershock is the latest in a series of shaking that has taken place since last Friday's quake. The USGS said more than 40 aftershocks have occurred since Friday with most being 2.0-magnitude or less.

So how long can the area expect to possibly feel additional aftershocks? The chance will still around for at least some time, experts say. In many cases, aftershocks can occur for at least a week after the initial earthquake, experts say. The USGS said there is a 21% probability of a magnitude 3.0 or higher aftershock in the first month after this particular earthquake and a 3% chance of a magnitude 4.0 or higher.

According to the USGS, "Aftershocks are smaller earthquakes that occur in the same general area during the days to years following a larger event or 'mainshock.'"
