Tremors felt by some Northeast Philadelphia residents early Wednesday morning proved to be a legitimate earthquake “event” according to a seismographic network with Columbia University.
The very small earthquake registered .5 on the Richter magnitude scale, according to officials at the Lamont-Doherty Cooperative Seismographic Network.
One woman, who lives near the Franklin Mills Mall, told NBC Philadelphia that she felt the tremors at 2:40 a.m. and 7:20 a.m.
Some residents said they thought the vibrations were from someone breaking into their homes.
