A Pwave is the first wave to arrive during an earthquake, P waves compress and then expand. They can damage buildings.
The biggest seismic waves are surface waves, which travel along the Earth's surface and are usually the most destructive during an earthquake. The two main types of surface waves are Rayleigh waves and Love waves. Rayleigh waves cause the ground to move elliptically in vertical and horizontal directions, while Love waves cause horizontal shearing motion.
The P wave on an ECG represents atrial contraction. It signifies the depolarization of the atria as they contract to push blood into the ventricles.
p wave comes first s wave comes next and last comes surface wave.
