To determine which station was closest to the earthquake, you can analyze the seismic data recorded by each station. By calculating the time difference between the arrival of P-waves and S-waves, you can estimate the distance to the epicenter using the known velocities of these waves. The station with the shortest time difference will be the closest to the earthquake's epicenter. Comparing these distances will help identify the nearest station.

A compass perhaps?

A compass?
There are several different types of compass:magnetic compass, uses a light weight bar magnet on a pivotgyroscopic compass, uses a gyroscope (either mechanical or LASER ring)drawing compass, used to assist in drawing circles for drafting or artetc.
For navigation, it shows you what direction you are facing. In drawing, it is a device for drawing circles.
