WebOrientation... there are vertical and horizontal orientated versions which allow you to create a true tri-axial configuration using 3 geophones (1 … 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. See more The term geophone derives from the Greek word "γῆ (ge) " meaning "earth" and "phone" meaning "sound". See more The frequency response of a geophone is that of a harmonic oscillator, fully determined by corner frequency (typically around 10 Hz) and … See more • Accelerometer • Hydrophone • Michelson interferometer • Seismometer See more Geophones have historically been passive analog devices and typically comprise a spring-mounted wire coil moving within the field of a case … See more The majority of geophones are used in reflection seismology to record the energy waves reflected by the subsurface geology. In this case the primary interest is in the vertical motion of the Earth's surface. However, not all the waves are upwards travelling. … See more • PSR-1 Seismic Intrusion Detector (Vietnam era military device) See more eastwood service station leigh on sea https://ascendphoenix.org
