A shadow zone occurs on the opposite side of the earth from an earthquake because of the liquid outer core SWaves are stopped all together while the PWaves are refracted (bent) to create a zone where no waves are picked up at all This zone is between 102° and 143°around the earth from the earthquakeSeismic Shadow Zones S wave shadow zone The shadow zone results from S waves being stopped entirely by the liquid core Three different Swave phases show how the initial S wave is stopped (damped), or how it changes when encountering boundaries in the Earth
The s-wave shadow zone occurs because
The s-wave shadow zone occurs because-Small SPinterval very large SPinterval There would be no Por S waves, because Bakersfield is in the shadow zone ThereThe Swave shadow zone occurs because no Swaves reach the area on the opposite side of the Earth from the focus Since no direct Swaves arrive in this zone, it implies that no Swaves pass through the core This further implies the velocity of Swaves in the core is zero In liquids,
Seimic Waves And Earth S Interior
Because of the refraction that takes place at the CMB, waves that travel through the core are bent away from the surface, and this creates a Pwave shadow zone on either side, from 103° to 150° This information can be used to discover the differences between the inner and outer parts of The S wave shadow zone is caused by the outer core not transmitting S waves It crosses an arc of 105 degrees on the Earth (see the diagram on the left) Estimate the radius of the outer core The radius of the entire Earth is 6370 kmThe area beyond 105 degrees of distance forms a shadow zone At larger distances, some P waves that travel through the liquid core would arrive, but still no S waves READ Hawaii 1946 Sugar Strike The Earth has to have a molten, fluid core to explain the lack of S waves in the shadow zone, and the bending of P waves to form their shadow zone
A zone between 105° and 145° from the epicentre was recognized as the shadow zone for both the wave types The entire zone beyond 105° does not receive Swaves The shadow zone of Swave is larger than that of the Pwaves The shadow zone of Pwaves appears as a band around the earth between 105° and 145° away from the epicentre S waves dont even reach the shadow zone because they are unable to penetrate the outer core They are basically stopped by the shadow zone It depends on where the earthquake occursS wave a shadow zone appears when the velocity suddenly decreases degrees from the epicenter Describe the differences between P and S waves P waves expand and contract, can move through liquid solid and gas

Shadow zone 1 A region of the subsurface from which seismic reflections cannot be detected because their raypaths do not emerge to the surface 2 A zone over the Earth's surface in which Pwaves and/or Swaves generated by an earthquake are detected only weakly, or are absent, because of refraction within the various layers deep within the Earth, and especially in Measuring the arrival of seismic waves at stations around the world Swaves were not able to pass through outer core so it means that it is liquid "shadow zone" occurs because swaves did not reach the opposite side of the earth There is a solid core because pwaves are reflected off the boundary between inner and outer core
