The waves that are slower that those that originate at the focus are called secondary waves or S-waves. They are shear waves that are transverse in nature.
Seismic p
S-waves are stronger, but travel slower and can only travel through solids.
Tidal waves originate deep within the ocean and end once they reach the coast. They are typically caused by large earthquakes which send shock waves outward from the epicenter.
The Transverse waves show up second in time, they are slower than the Primary Waves.
p waves
Surface waves are slower than body waves like P-waves and S-waves because they travel along the Earth's surface instead of through the interior. Surface waves typically cause the most damage during an earthquake due to their combination of horizontal and vertical motion.
p waves
Surface waves do not originate from the focus. These waves are created when seismic energy reaches the Earth's surface and move horizontally along it, causing the ground to move in a rolling motion.
Seismic p
The center of a seismic wave is called the focus or hypocenter. This is the point within the Earth where the seismic waves originate.
In geological terms, it is the point below the Earth's surface where seismic waves originate during an earthquake.
It is the focus or hypocenter and is the point of initial breakage and movement along the fault.
only faster not slower.
Primary (P) waves : Primary waves, the fastest wave sent , come from the focus not the epicenter. (S) waves : Secondary waves, the second fastest wave sent out by an earthquake, it comes from the focus also.
Surface waves move slower than P waves and S waves. They travel along the surface of the Earth and are primarily responsible for the damage caused by earthquakes, as they have a larger amplitude and longer period.
S-waves are stronger, but travel slower and can only travel through solids.
The point directly below the epicenter of an earthquake is known as the hypocenter or focus. This is where the seismic waves originate and the point within the Earth where the energy is released from the seismic event.
