WebMay 6, 2024 · The result is a P-wave shadow zone. No P-waves are picked up at seismographs 104° to 140° from the earthquakes focus. Figure 1. How P-waves travel through Earth’s interior. S-waves (secondary waves) are about half as fast as P-waves, traveling at about 3.5 km (2 miles) per second, and arrive second at seismographs. S … WebA P wave ( primary wave or pressure wave) is one of the two main types of elastic body waves, called seismic waves in seismology. P waves travel faster than other seismic waves and hence are the first signal from an earthquake to arrive at any affected location or at a seismograph. P waves may be transmitted through gases, liquids, or solids.
