An earthquake of moderate intensity was recorded at the Harvard Seismography Station Saturday morning, beginning at 2.14 o'clock. The distance from Cambridge is computed as approximately 4300 miles and the time at the origin at 2.03 o'clock. This distance from Cambridge crosses several active seismic areas including one on the Aleutian Islands off Alaska, one in South America. Italy and Central Europe. The exact location cannot be determined from the records of a single station, however the character of the record in this case, suggests South America as the probable source of the disturbance.
