WebCHAPTER 1: GENERAL GEOPHONE INFORMATION 1.1 Background on Geophones . This chapter will go into further detail of how a commercial geophone works and also practical uses for commercial geophones. As mentioned in the introduction, a geophone is a device which detects motions in the earth and converts detected motions into voltage. A geophone is a device that converts ground movement (velocity) into voltage, which may be recorded at a recording station. The deviation of this measured voltage from the base line is called the seismic response and is analyzed for structure of the earth. Meer weergeven The term geophone derives from the Greek word "γῆ (ge) " meaning "earth" and "phone" meaning "sound".

WebGeophones—also called jugs, pickups, and tortugas—are placed on the ground surface in various patterns, or arrays, to record the vibrations generated by explosives in seismic reflection and refraction work. They also are used as military detection devices. See also seismic survey. This article was most recently revised and updated by Mic Anderson. WebMost geophones have through-holes for anchors installed in the structure. The geophone is slipped onto a threaded anchor and held in place by a washer and tightened nut. Horizontal geophones are always oriented with the arrow pointing toward the source of vibration. Wall Installation Vertical geophones are available for installation on walls.
