Which statements describe the location of an earthquakes epicenter? check all that apply. 1) it is measured by a seismograph 2) is is located using a single set of data 3) it is determined by the arrival times of s and p waves 4) it is determined by the arrival time of surface waves 5) it is located at the point where circles intersect on a map

The answers are; 1, 3 and 5

Seismographs are used to detect earthquakes and also extrapolate their epicenters. More than one seismographs are required to locate the epicenter through a mathematical method called Triangulation.  The epicenter can also be extrapolated by using an extrapolation map that deduces the distance to epicenter using the difference in time between the primary and secondary waves of the earthquake.
