Answer:
The P waves undergoes compression and dilation during motion in its direction of propagation. This waves reaches the station first because the P waves travels at a speed, that is much faster in comparison to the S waves. The S waves are the secondary waves and are commonly known as the shear waves.
The P waves have the ability to travel in both solid as well as in liquid, whereas the S waves can propagate only in solid region because they are absorbed at the core-mantle boundary.
Thus, the P waves will arrive the station first and the difference between the arrival of P and S waves are plotted in the graph that helps in depicting the epicenter and the amount of energy released during an earthquake.
The seismograph station is one that keeps monitoring the data generated by the seismic events
- They consist of a device known as a seismograph that measures the ground noise and shaking created by the earthquake.
- The P waves are primary waves and the first to reach the epicenter have the ability to travel through the liquid and solid medium as compared to the secondary S waves.
- Hence the P waves travel the fastest and will arrive early than S waves. Hence the P and S waves travel through different intensities.
