Camden, NJ Earthquake, Aug 1884
Camden experienced an earthquake. It came on a Sunday afternoon, August 10th, 1884, a clear day, about ten or twelve minutes past two o'clock, without rumble or other warning, in three distinct tremors, the last lighter than the first two and was over in a few seconds. The wall of strong stone houses shook perceptibly and the bells in large brick houses rang. People walking along the street appeared not to notice it, but to many within well-built houses the sensation of irresistible trembling of floors and distinct shaking of stout walls gave a feeling of instability never before experienced. The earthquake was very general over the Eastern United States, toppling over chimneys, but doing little other damage.
