WebDec 13, 2024 · Seismic waves are waves of energy that travel through the Earth’s layers and are a result of earthquakes, volcanic eruptions, magma movement, large landslides and … WebDec 16, 2024 · P-waves (primary waves) and S-waves (secondary waves) are two types of low frequency seismic waves created by earthquakes. As P-waves (which vibrate parallel to the direction of wave movement) move through the earth, they slow down in the core and refract (Figure 1). This results in a ring-shaped region on the other side of the earth from …
WebCertain magnitude is necessary to cause an earthquake. Region on earth’s surface where earth quake can be barely detected after an occurrence of a seismic wave is called shadow region. In the given options all are correct but the statement ‘P-wave shadow zone is larger than the S-wave shadow zone ’ is false and vice versa is true. A seismic shadow zone is an area of the Earth's surface where seismographs cannot detect direct P waves and/or S waves from an earthquake. This is due to liquid layers or structures within the Earth's surface. The most recognized shadow zone is due to the core-mantle boundary where P waves are refracted and S waves are stopped at the liquid outer core; however, any liquid boundary or body can create a shadow zone. For example, magma reservoirs with a high enough percent m…
WebThe 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°. WebThe S-wave shadow is a region where? Earths LIQUID OUTER CORE does NOT transmit S-waves. Seafloor Spreading provided the mechanism for Continental Drift because at the …
WebSeismographs installed in remote regions record earthquake waves. There are, however, some regions where the waves are not reported. The 'shadow zone' is a term used to describe such a region. The examination of several disasters demonstrates that each earthquake has a distinct shadow zone. It was discovered that seismographs placed …
