NJ is booming and shaking

Did you hear booming noises this AM in central New Jersey? There was a small, shallow earthquake about 3km north of Bernardsville.

The U.S. Geological Survey confirmed the small earthquake in Bernardsville rattled homes and businesses around 3:41 a.m.

The Morris County Communications/911 center received calls from residents in Morristown, Morris Township, Randolph, Mendham Township, Mendham Borough, Chester Township and Chester Borough, spokesman Jeff Paul said.

The magnitude was around 2.7 and occurred on a small fault that is not a threat for larger quakes. The northeast has occasional small, shallow quakes like this that will rattle people inside but do not cause much damage. Shallow quakes may be accompanied by booming sounds, as we regularly report here, because the energy can be transmitted into the air. Some on Twitter reported they hear “explosion” noises.

    Explosions cause small earth tremors also. The wave form illustrated on the DN top page linking this page is typical of an explosion: Abrupt onset, asymptotic decay.
