3. seismograph
   a device that detects vibrations in the earth. It is used in studying the earth's interior and in prospecting for probably oil-bearing structures. Vibrations are created by discharging explosive in shallow boreholes, by striking the surface with a heavy blow, or by vibrating a heavy plate in contact with the ground. The type and velocity of the vibrations are recorded by the seismograph indicate the general characteristics of the section of earth through which the vibrations pass.

5. Seismograph
   an instrument that records the frequency and magnitude of seismic waves. The vibrations are recorded by a pen on a revolving drum. A seismography can pick up seismic activity thousands of kilometres away.

14. Seismograph
    A very sensitive instrument used to record and measure earthquakes. During an earthquake, vibrations initiated by fracturing of the earth's crust radiate outward from the point of fracture and are detected by seismographs. The visual record produced is called a "seismogram".
