Discovery of a new type of underground earthquake wave, vitally affecting seismological theories and problems of building reinforcement, was reported today by Dr. L. Don Leet, Director of the University Seismograph Stations...
Disclosed by a series of observations of artificial earthquakes set off by dynamite explosions, the new wave-form is the fifth fundamental type known to science. The four previously known forms have been recognized for forty years. Dr. Leet said his new wave was not predicted in earthquake theory...
...Leet, assistant professor of Geology, returned yesterday from South Carolina where he conducted experiments penetrating the earth to record depths in order to determine geologic structure by the seismic method...
Thanks to the generosity of Godfrey L. Cabot '82 the Geology department had at its disposal for scientific experiment a 6000 ft. oil well near Charleston. Although this well never yielded any oil, it provided an excellent opportunity for Leet's important research work...
...extremely well," said Leet in an interview yesterday. "By lowering portable seismographs into the well and exploding dynamite at successively greater depths, 500 ft., 1000 ft., and 2000 ft., we were able to gain perfect records at every position. We also made some surface record...
