Dear All, I hope you can point me in the direction. I am interested in finding P-wave and S-wave velocities from earthquake data. However, I couldn't find any particular article or methodology explaining how I can get the P and S velocities from the Earthquake dataset. Looking forward to your suggestions...

Physics does not provide an answer to your question.
You know the coordinates of the seismic station and the exact time of arrival of the seismic wave.
You can know the exact time of an earthquake. You can know the exact coordinates of the epicenter. You can even hope that you know the depth of the hypocenter.
Unfortunately, you cannot know the length of the path along which a seismic wave propagates, that is, the trajectory of a mechanical wave.
Unfortunately, you cannot know how the speed of a mechanical wave changes as it travels from the hypocenter to the seismic station. You understand that the speed of a seismic wave in a real geological environment is not a constant...
A good Computer Code for such computations is VELEST.
I hope it is still incorporated in SEISAN software. Free download it and see it is useful to you.
Good Luck !
There is a large community of Seismologists using SEISAN. They will provide you with support.
