No they ARE caused by the recession of the first wave which IS caused by an earthquake.
secondary
brings waves to the surface to create a earthquake
Surface waves typically cause the most damage in an earthquake. These waves travel along the Earth's surface and have longer periods, resulting in strong shaking that can cause buildings and other structures to collapse. Secondary waves, on the other hand, are faster but typically cause less damage compared to surface waves.
P waves (primary waves) and S waves (secondary waves).
Earthquake waves are vibrations that travel through the Earth's crust when an earthquake occurs. There are three main types of earthquake waves: primary (P) waves, secondary (S) waves, and surface waves. These waves can cause the ground to shake and can be detected by seismographs.
S waves, or Secondary waves, are earthquake waves during an earthquake. They crash after P waves ( Primary waves) and are less stronger than surface waves
The secondary or S waves arrive second at a seismometer after an earthquake. These waves move slower than the primary or P waves and typically cause more damage due to their side-to-side shaking motion.
how far away you are from the focus of an earthquake
The three types of earthquake waves are primary waves, surface waves, and secondary waves.
P or primary wave, S or secondary waves, L as in something waves
a surface wave is a earthquake it comes last. It goes Primary waves, Secondary waves, and Surface waves.
Love waves are the most strongest type of Earthquakes.
