A magnitude 3.0 earthquake that rocked several towns in Morris County Monday left no reported injuries or significant damage so far, authorities said. It might seem weird--earthquakes in our backyard?--but quakes of varying degrees are not an anomaly in Central New Jersey. Sitting on a fault called the Ramapo Fault, which separates the Piedmont and Highlands Physiographic Provinces, our area has suffered many small tremors and quakes over the last 200+ years. The Ramapo Fault Zone, a 10 to 20 mile wide area lying adjacent to, and west of, the actual fault, is where most of the seismic activity occurs.

The highest intensity earthquake ever observed in New Jersey occurred on June 1, 1927, in the Asbury Park area. Three shocks were felt along the coast from Sandy Hook to Toms River and extended over approximately 7,800 square kilometers. On January 24, 1933, a sharp jolt was felt over central New Jersey from Lakehurst to Trenton. The shock was felt most strongly around Freehold, Hightstown, New Egypt, Robbinsville, and White Horse. An August 22, 1938, quake in Central New Jersey caused a shock somewhat stronger than the 1933 event. The earthquake caused minor damage at Gloucester City and Hightstown and felt as far away as Ardmore, Pennsylvania. Four smaller shocks occurred on August 23rd and one on August 27th.
