surface waves because p waves and s waves are way faster so here is how it goes from fastest to slowest: is p wave and then s wave and then surface waves
P-waves(primary waves) travel faster than S-waves(secondary waves)
P-waves are longitudinal and S-waves are transverse waves.
P waves arrive a couple seconds to a few minutes before s waves.
P-waves and S-waves are released by an earthquake at the same time and travel out from the epicentre in all directions. However P-waves travel faster than S-waves so the further away from the earthquake's epicentre the greater the lead the P-waves have on the S-waves. Observation of the seismogram trace at the seismometer station will allow the scientists to find the P-wave and S-wave arrival times and measure the difference between them. As the P-waves are faster they always arrive first (hence their name - primary wave). The greater the difference between the time that the P-waves and S-waves first arrive (i.e. the greater the lead the P-waves have), the further the distance to the epicentre. They are able to use the time difference along with an estimate of the speed of the P-waves and S-waves to find the distance from the station to the earthquakes epicentre. For more information on this please see the related question.

It is because the epicenter decreases their strenght as it is closer to it
No, surface waves move slower than P-waves and S-waves. P-waves are the fastest seismic waves, followed by S-waves, and then surface waves. Surface waves travel along the Earth's surface and are responsible for the most damage during an earthquake.
P-waves(primary waves) travel faster than S-waves(secondary waves)
p waves because they move rock back and forth which squeezes and strecthes the rock as they travel through the rock. s waves shear rock side to side as they travel through the rock
P-waves, also known as primary waves, travel faster in a solid compared to S-waves, secondary waves. P-waves are compressional waves that can travel through both solid and liquid layers, while S-waves are shear waves that can only propagate through solid materials.
no p waves travel faster than s waves
The fast is primary wave which travels through liguid, solid and gas. This how Geologist know the outer core is liquid. Secondary waves travel through only solid. The primary wave are the first to reach the seismograph.
P waves travel about 1.7 times faster than S waves. This difference in speed allows seismologists to determine the distance of an earthquake from a seismographic station.
Primary waves travel at 6 to 7 km per second. Secondary waves travel at about 3.5 km per second. which means that the p-wave travels about 3 km. faster
P-waves are faster than s-waves. Both can pass through solid rock, but only p-waves can pass through gases and liquids === ===
