P-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.
Elastic potential energy stored in the rock is released in the form of vibrations and heat.
Longitudinal waves that are produced by earthquake are called primary waves because they are detected by seismometers before the other types of seismic waves due to their higher velocity which means they travel from the epicentre of an earthquake to the seismic station more quickly than the other types of seismic waves.
the different kinds of earthquake are the : 1.TECTONIC EARTQUAKE 2.ARTIFICIAL EARTHQUAKE 3.VOLCANIC EARTHQUAKE
There are four different types of earthquakes - tectonic, volcanic, collapse and explosion. A tectonic earthquake is one that occurs when the earth's crust breaks due to geological forces on rocks and adjoining plates that cause physical and chemical changes.
The two types of earthquake scales are the Richter scale and the moment magnitude scale. The Richter scale measures the amplitude of seismic waves, while the moment magnitude scale accounts for the energy released by an earthquake.
seismic
During an earthquake, seismic waves are released. These waves travel through the Earth and can be detected by seismographs. The main types of seismic waves are P-waves (primary waves), S-waves (secondary waves), and surface waves.

Quantitive evidence is evidence that has to do with numbers. For example. the magnitude of an earthquake the time the earthquake occurred and the length of the earthquake are all types of quantitive evidence
Before an earthquake nothing perceptible to humans happen. Several types of animals act up though. During a earthquake the ground trembles. Depending on the magnitude this might be anything from a light tremble to a violent shaking. Most of the time nothing happens after an earthquake, but sometimes there is an aftershock, which is another earthquake of a lesser magnitude.
