...earthquake was observed in the seismograph at the University observatory at 9.21 o'clock yesterday morning, according to Professor K. F. Mather, Professor of Geology. The quake was one of unusual intensity, not reaching its maximum until 14 minutes after the first tremor. The seismograph record indicated that the disturbance was about 4500 miles in a southerly direction from Cambridge...
...Washington, D. C., the needle of the seismograph at Georgetown University twitched nervously; later, it jazzed. An earthquake, 2,400 miles distant, was registered...
...earthquake which rocked Cambridge and the entire eastern part of the country about 9.30 Saturday night threw the stylus of the University seismograph in Peabody Hall off the east-west component of motion, according to Professor R. A. Daly G. '95, of the Department of Geology, but did not prevent taking a record of the shock...
...strength and the wide area of disturbance. The center seems to have been about 100 miles distant from Boston either to the cast or west." Professor J. B. Woodworth, the University seismologist, is absent on sabbatical leave in Florida and hence cannot read the record of the seismograph. The cylinder has therefore been shellacked, and will be sent to Washington for study...
According to Professor K. F. Mather of the Geology Department, the University seismograph showed that the shock occurred at 8.07 o'clock yesterday and lasted for 45 seconds. He believes that yesterday's quake was due to a shifting, either vertically or horizontally, of the great Fundian fault in the earth's crust which is submerged under the Bay of Fundy. He bases his opinions on the fact that the two waves of the shock came in quick succession. A quake always divides into two waves which separate as the earthquake travels. Since the two shocks were simultaneous, the origin...
