terms:seismograph
A device which records vibrations in the earth, detected by geophones, used in prospecting for probable oilbearing structures. Vibrations are created by discharging explosives in shallow boreholes or by striking the ground surface with a heavy blow. The type and velocity of the vibrations (as recorded by the seismograph) indicate the general characteristics of the section of earth through which the vibrations pass.
