seismic
The vibrations that move away from an earthquake's origin are known as seismic waves. There are two main types of seismic waves: primary (P) waves, which are compressional waves that travel fastest through the Earth's interior, and secondary (S) waves, which are shear waves that move more slowly and can only travel through solids. Both types of waves propagate outward from the earthquake's focus, causing the ground shaking associated with seismic events.
There was a big earthquake in 2010 in Haiti. The earthquake was 7.0
P waves or pressure waves are the fastest traveling, and tend to be the primary waves to hit after an earthquake has begun. As such they tend to not be as destructive as the waves that follow. The most destructive waves tend to be the aftershock waves of an earthquake because the structural integrity of a building becomes comprimised by the main event of the earthquake causing it to not be able to withstand the after shocks despite the diminished seismic magnitude of the aftershock waves. The energy of all land based earthquakes are transmitted through the Earth's crust by seismic waves, (oceanic earth quakes tend to create oceanic tidal waves or tsunamis which can be very destructive as well) the force of which can be measured by a seismometer and recorded using the Richter magnitude scale which ranges from 2.0 (micro) to 10+ (epic). The amount of damage done to buildings, cities, and infrastructures depends entirely on the magnitude of the earthquake, their location relative to the epicenter of that earthquake, and the overall stability, structural integrity, and earthquake preparedness of that building, city or infrastructure. As an example, the recent tragic catastrophy in Haiti was devistating due not only to the fact that the earthquake was a magnitude 7 (major) on the Richtor magnitude scale but the structural integrity of many of the buildings was deteriorating and the infrastructure to respond to the damage caused by a major earthquake was not as well established and prepared as it could have been because of the level of poverty that the whole country suffers from. Because of those factors, the earthquake in Haiti was very destructive and catastrophic not only to the indevidual buidlings but to the national infrastructure as well, (meaning that the sea ports and airports were destroyed and are having a hard time receiving aid, and the first responders to the earthquake are not as prepared for a catastrophe of this magnitude as they could have been.) An earthquake of the same magnitude in a city like Las Angeles would probably not cause the same severity of trauma and destruction to the buildings and infrastructure of the city itself due to the earthquake preparedness of that region and the well established financial infrastructure and supporting networks of the region and surrounding states.

Seismic waves, such as compressional (P-waves) and shear (S-waves), can deform rocks by alternately compressing and stretching them as they pass through the Earth's crust during an earthquake. This can lead to the fracturing and displacement of rock layers.
Earthquake waves are called seismic waves.

seismic waves
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.
Seismic waves are released during an earthquake. These waves can be classified into two main types: body waves, which travel through the Earth's interior, and surface waves, which travel along the Earth's surface. The movement of these waves is what causes the ground shaking experienced during an earthquake.
An earthquake deep underground releases seismic energy in the form of seismic waves. These waves carry energy from the point of the earthquake's origin (the focus) and cause the ground to shake as they propagate through the Earth's crust.
