The seismic shadow zone is the rea of the Earth's surface where seismographs cannot detect an earthquake after the waves have passed through the earth. P waves are refracted by the liquid outer core and are not detected between 104° and 140°. S waves cannot pass through the liquid outer core and are not detected beyond 104°.

At the station, the seismograph is connected to L-C4 short period vertical component seismometer for generating the seismic signal.Reflection Seismology. Reflection seismology began to take prominence in the 1920s to begin to locate salt domes, an indication where oil would be found. The reflection method soon replaced the refraction after it was proved with numerous successes, the most visible in the petroleum industry. Lets Start With a Single Subsurface InterfaceWhy Do Earthquakes Happen? Most faults in the Earth’s crust don’t move for a long time. But in some cases, the rock on either side of a fault slowly deforms over time due to tectonic forces. Earthquakes are usually caused when underground rock suddenly breaks and there is rapid motion along a fault. This sudden release of energy causes the ...A seismometer is a very sensitive instrument that can detect movements of the Earth's surface.
