The p-wave shadow zone

Webb29 aug. 2024 · Sometimes these refractions can result in shadow zones, which are areas along the Earth where no seismic waves are detected. Due to the presence of a liquid outer core, a P-wave shadow zone exists from 103°-143° (see Figure 2.1) from the earthquake origination point (focus), and a larger S-wave shadow zone exists in areas greater than … WebbP waves are seismic waves that travel through the earth during an earthquake.

Webb16 dec. 2024 · 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 the earthquake in which no earthquake energy is received by seismometers.

WebbThe seismic waves called P-waves pass through the core and are detected on the far side of the Earth.
