Method: seismology and seismic exploration

Seismology: study of natural (earthquakes) and man-induced ground and subsurface waves. Seismology refers to the study of how energy, in the form of seismic waves, moves through the Earth's crust and interacts differently with various types of underground formations. In 1855, L. Palmiere developed the first 'seismograph', an instrument used to detect and record earthquakes. This device was able ....

Seismograph

Seismic Instruments examines a wide diversity of geophysical instruments: seismometers, computerized digital seismic stations, ocean bottom and borehole seismic stations, automation of geophysical monitoring, strainmeters and tiltmeters. Marine and Land seismographs. Multi-channel seismograph for LVL and engineering seismic applications. Exploration seismograph SUMMIT X Stream Pro Value quality seismograph for engineering application. A seismometer is an instrument that measures motion of the ground, caused by, for example, an earthquake, a volcanic eruption, or the use of explosives.Exploration seismograph SUMMIT II Ex Intrinsically safe seismograph for use in underground mining. The traditional compact 24-channels ...A seismograph is a device used for recording earth tremors. Basically, it is a heavily weighted horizontal rod (pendulum) suspended from a pole.

Article 4

Electromagnetic Induction - EM

EM devices can simultaneously examine soil conditions and locate objects found beneath the surface of the earth spatially, but do not provide good depth information. The basis of the electromagnetic technique is the use of a coil with an alternating current circulating within it.
