P-waves are the first to arrive at a seismic station.
There are two major types of waves: Body waves and surface waves. P-waves and S-waves come under Body waves while Love and Rayleigh waves come under surface waves. Body waves are much faster than the Surface waves. Waves are detected in the following order: P, S, Love and Rayleigh

The first seismic waves to arrive at a seismic station are usually the P-waves, also known as primary or compressional waves. These waves are the fastest seismic waves and can travel through both solid and liquid materials.
P-Waves are the fastest seismic wave and as such are the first to arrive at a given seismic station.
Surface waves arrive last at a seismograph station. These waves move along the Earth's surface and are the slowest of the seismic waves, but they can cause the most damage during an earthquake.
The distance between a seismic station and the earthquake epicenter is determined by measuring the time it takes for the seismic waves from the earthquake to arrive at the station. By analyzing the arrival times of the different types of seismic waves (P-waves and S-waves), scientists can triangulate the epicenter location using multiple seismic stations.
The seismograph station closest to the earthquake epicenter would have recorded P-waves first, followed by stations farther away. Since P-waves are the fastest seismic waves, they are the first to arrive at a seismograph station after an earthquake.
No, surface waves are typically the last seismic waves to arrive at a seismic facility. They travel more slowly than body waves (P and S waves) and arrive after the initial shaking caused by the faster body waves.
No, P-waves are the first seismic waves to arrive at a given location. P-waves are faster than S-waves and can travel through solid and fluid materials, whereas S-waves only travel through solid materials.
