A surface wave is the last seismic wave to arrive after an earthquake.
P-waves are normally the first to register on a seismograph.
First is P-waves (P stands for primary).
Second is S-waves (S stands for secondary).
An S-wave is commonly known as an aftershock.

Seismic waves are the forms of energy produced by an earthquake.
P or Primary waves are the fastest earthquake or seismic waves.

P waves
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 way seismic waves are different are that they're slower than the p waves who move a lot faster to reach the earthquake.

Primary and secondary waves.
Seismic waves are any waves that travel through the Earth. As such all earthquake waves are seismic waves, however not all seismic waves are caused by earthquakes.
Seismometers or Seismographs are instruments that measure motions of the ground, including those of seismic waves generated by earthquakes, volcanic eruptions, and other seismic sources.
Seismic waves end at an earthquake's center.
A seismograph is one such instrument...there might be others.
Seismic waves occur when there is an earthquake.
There is a network of seismometers (earth-quake detectors) setup around the world. When an earthquake occurs it releases a set of powerful waves which travel through the Earth and are detected by the seismometers. By comparing the time taken to reach each seismometer the epicentre of the earthquake can be triangulated.
