News wires soon burned with the flash that a giant rockfall had plunged from the brink of the American Falls. Buffalo hastily reported that the shock had registered on the seismograph of Canisius College. An engineer of the Niagara park commission estimated the break to be 125 feet across and 30 feet deep, added that his view had been partly obscured by the mists. The reliable Associated Press released an aerial photo carefully marking the "Break of September 20, 1946." Said a Page One headline in the sober New York Times: AMERICAN FALLS NOW A HORSESHOE...
Another in the series of Caribbean earthquakes was reported yesterday at 10 minutes, 43.5 seconds after 6 o'clock this morning, by the University seismograph station, at Harvard, Massachusetts. The center of the shock was reported to be 1,500 miles south of the station...
...aged wood and fine Italian hand of the old violin makers. It was fashioned by Caltech's seismologist Dr. Hugo Benioff, who gave up violin playing as a boy because he couldn't stand the noise he made. Eighteen years ago, when he was designing seismographs to measure earthquakes, he decided that there wasn't much difference between a seismograph and a fiddle "except one deals with slow movements and the other with rapid movements." For his scientific cello he mounted a conventional fingerboard and electrified bridge on a heavy wooden frame and stood the whole thing...
...soon after the blast as anyone was sufficiently composed to consult the seismograph, the investigators discovered the presence of an entirely new wave which no one had heretofore expected from even the most scrupulous of predictions. Leet christened the new wave the "hydrodynamic wave" because of its similarity to the motion of a ripple on an aqueous surface...
...just finished making a new portable seismograph, designed to record the earth vibrations caused by dynamite explosions. That was last spring. Like most Americans, Harvard's Professor L. Don Leet had never heard of the Manhattan Project. But in June, the professor was tapped lightly on the shoulder and spirited away to New Mexico. There his new gadget went to work recording the biggest man-made explosion in history...
