Tremors from a 4.8 magnitude earthquake near Whitehouse Station, NJ were felt across the East End on Friday morning.

George Lomaga, a retired astronomy and geology professor who taught at Suffolk County Community College, said that the earthquake was rather shallow, only about a mile deep underground and that deeper earthquakes tend to cause more damage.

Mr. Lomaga said Friday morning’s earthquake was caused by bedrock shifts and slides in the Ramapo Fault, which runs through New York, New Jersey and Pennsylvania. Mr. Lomaga said to think of the shaking felt along the East End like the “ripples caused when throwing a stone in the water.”

Based on the movements noted in the fault line, Mr. Lomaga said it’s possible to have an earthquake every 10 to 20 years. He also noted that aftershocks are possible, but there is no way to tell if they will happen or be felt.

Southold Police Captain Steven Grattan said that the department received many inquiries following the tremors but that no injuries were reported. The department could not confirm if a downed wire on Cox Lane was related to the quake.
