...Lett, assistant Professor of Geology, leaves tomorrow for Charleston, S.C., where he will carry out revolutionary experiments on the seismic method of determining geologic structure...
Lett's experiments on the seismic method of determining will thus involve two fundamental geologic principles. In the first place he will use as a basis the recording of earthquake waves, which give information on depths of the earth...
Among Mayflower's "hazardous ventures" was to put up $300,000 to further the seismic explorations of F. Julius Fohs, an oil geologist. Eventually Geologist Fohs discovered the English Bayou Oil Pool in Louisiana and Mayflower stock-holders received stock in Fohs Oil Co. now worth $2,500,000. Another venture was a $4,000,000 investment in Rhodesian copper properties, a commitment which was long thought to have been fabulously profitable. Actually, Mayflower lost...
...general, there are two approaches to the problem of predicting seismic disturbances. One is by observing certain phenomena which have been found to precede them. These are slight tiltings of the ground, as detected in Japan by Inouye and Sugiyama; changes in the force of gravity, as reported from Germany by Tomaschek and Schaffernicht; and disturbances of electromagnetic radiation, as observed by Italy's Piatti. No successful forecast has resulted from any of these observations. The other approach is to take cognizance of possible contributing causes of quakes, such as the tidal pulls on Earth of heavenly bodies. Herbert...
...shale charred red and yellow. On the other hand. Dr. S. Boyd Calkins, science teacher in the Durango high school, points to the earthy effusions which last week oozed from Carbon's cracks. These outpourings, he reasons, rose from, depths of 2,000 or more feet, definitely indicating seismic churnings along an earth fault which extends under Durango from Ute Peak in New Mexico to the Rocky Mountains...
