Earthquake History from the U.S. Geological Survey

August 22, 1938. "The earthquake caused minor damage at Gloucester City and Hightstown (Intensity V). The total felt area was about 13,000 square kilometers, including bordering portions of Delaware and Pennsylvania. Glassware was broken at Gloucester City and Hightstown and some furniture was displaced at Pitman. A few windows and some glassware were reported broken at Ardmore, Pennsylvania. Four smaller shocks occurred on August 23rd and one on August 27th."

November 14, 1939. "Residents of Salem County were startled by earthquake tremors on November 14, 1939, which caused more excitement than damage. The disturbance was reported felt from Trenton to Baltimore, Maryland, and from Cape May to Philadelphia and its adjoining counties. About 16,000 square kilometers were affected. Small objects were reported to have overturned at Deepwater, but little or no damage was noted."

December 27, 1961. "In northeastern Philadelphia and adjoining portions of New Jersey and Pennsylvania residents were alarmed by loud rumbling sounds on December 27, 1961. In New Jersey, the tremor was felt by many at Bordentown and Trenton, where houses shook (intensity V) and windows and dishes rattled. A similar disturbance affected much of the same area about seven years later when on December 10, 1968 an earthquake measured at magnitude 2.5 occurred in Burlington County. The press reported some broken windows. Intensity V effects were noted at Camden, Morrestown and at Darby and Philadelphia, Pennsylvania. It was reported that toll booths on the Benjamin Franklin and Walt Whitman Bridges in Philadelphia trembled during the shock."

May 12, 1964. "A strong local shock, measured at (Richter) magnitude 4.5, cracked a wall and caused some plaster to fall (Intensity VI) at Cornwall on May 12, 1964. Slight landslides were reported in the area. In one building, a radio was knocked from a table and a wall mirror moved horizontally. Workers in an iron mine about 360 meters underground were alarmed by a 'quite sever jarring motion.'"

Fairview Witness: "I was lying in bed on the second floor of our home at 2848 Idaho Road when a tremor aroused me from sleep. I felt vibrations from deep below the Earth. I was overwhelmed knowing that there was no escape. I heard the porch rattling. Then after just seconds everything stopped and was peaceful and calm." Michael J. Ruiz (age 14), 2848 Idaho Road. (Eighth Grade Student at St. Joan of Arc School, about to graduate in June).

December 10, 1968. "A small earthquake whose epicenter was in New Jersey caused intensity V effects at Darby, and Philadelphia. The December 10, 1968, shock was measured at (Richter) magnitude 2.5. Although relatively minor, it broke windows at a number of places in New Jersey. Toll booths on the Benjamin Franklin and Walt Whitman Bridges in Philadelphia trembled during the earthquake."

Fairview Witness: "I thought the heater blew up!" Margaret Wills (age 19), 3025 Porter Road.

February 28, 1973. "Most of New Jersey and adjoining portions of Delaware, Maryland, and Pennsylvania experienced a moderately strong earthquake on February 28, 1973. One town in southern Connecticut and one in eastern Virginia also reported the shock. The magnitude 3.8 tremor was centered in northwestern Salem County, near the Delaware River border with the State of Delaware. Observers reported cracked plaster (intensity V) at Laurel Springs and Penns Grove and cracked cinder blocks at Harrisonville. Also, small objects shifted and fell in several towns. Similar types of minor damage occurred in nearby areas of Delaware, Maryland, and Pennsylvania."
