People within a 10 to 20 mile radius of the blast thought tires, boilers, or explosives had blown up, but no property damage was reported. As the seismograph at Weston, Massachusetts, showed no ground tremors, L. Don Leet '29, associate professor of Geology, believed the explosion airborne, Smith added, "No airplanes, however, have been reported missing...
Four members of the Faculty of Arts and Sciences have received promotions, University authorities announced yesterday. Among those elevated is L. Don Leet '30, Director of the Seismograph Station at Harvard, Massachusetts, who has been made a full professor of Geology...
Professor Leet, one of the nation's leading seismologists, was among the scientists who took part in the Los Alamos atom bomb test two years ago. As a specialist in the study of vibrations, Leet has recorded the effects of earthquakes and blasts on his underground machines. He is the author of a forthcoming book on "Causes of Catastrophes...
Some startling facts have been brought to light through Leet's seismograph tests. In order to break window glass by concussion, charges must be fired in the open air, a most impractical thing in quarrying operations. Window glass must be subjected to pressures of 1 1/2 lbs. per square inch to break it, whereas air pressure at a few hundred feet from a quarry blast are 1 to two-thousandths of a pound per square inch, the same as those produced by a light summer breeze...
...Although Leet's instruments have proved scientifically that most industrial blasts cannot be of structural damage to nearby dwellings, the blasting companies still have to overcome most people's psychological reaction that where there's noise, there's damage...
