What kind of information do the seismic stations collect?

The seismic stations collect data that is related to the natural movement of the ground which is also called 'tremor'.

Explanation:

Seismic Stations are dedicated centers where the natural movements of ground are recorded on a seismograph (an equipment specially designed to trace the intensity of the earthquake). These stations are equipped with the required tools and technology to determine the hypo-center or the seismic focus of an earthquake which is usually deep below the Earth's surface.
