The focus of this shock was shallow, probably 10 km. or less. Six regional stations indicated a m eus of 4.6 and five teleseismic stations gave a mb of 4.3. A three-day micro-earthquake survey in the epicentral region recorded five definite and four possible seismic events with S-P times of less than five seconds.
Macroseismic data were gathered by field surveys and by questionnaires. These data indicated a maximum MM Intensity of V and a felt region of 125,000 square miles over nine Mid-Atlantic states.
