the direction from which surface waves arrive at several areas

the number of surface waves that arrive each minute at several areas
the number of surface waves that arrive each minute at several areas

the difference in strength between the p-waves and the s-waves at several areas

Answer 1

The most helpful seismic information for determining the epicenter of an earthquake is:

the amount of time between when a p-wave and an s-wave arrive at several areas.

This information allows scientists to calculate the distance from each seismic station to the epicenter based on the differing speeds of P-waves (which are faster) and S-waves. By using data from multiple seismic stations, they can triangulate the location of the epicenter.
