These waves travel in the speed range of 1.5-13 km/s. These waves are almost 1.7 times slower than P waves. These waves travel in a linear direction. These waves travel in a transversal direction. These waves can travel through solid, liquid, and gas.

What Are Some Differences Between P & S Waves?

Nettet1. sep. 2024 · They are defined based on when they arrive and are felt on the surface. P waves, or primary waves, arrive first while S waves, or secondary waves, arrive second. Both waves cause the ground to shake when an earthquake occurs. S waves cause more intense shaking than P waves and are typically much more destructive.

"Nettet11.3 Measuring Earthquakes. There are two main ways to measure earthquakes. The first of these is an estimate of the energy released, and the value is referred to as magnitude. This is the number that is typically used by the press when a big earthquake happens. It is often referred to as “Richter magnitude,” but that is a misnomer, and it ... " - How strong are p waves
