Final answer:
The epicenter of an earthquake can be located using at least three seismographic stations by measuring the arrival times of seismic waves.
Step-by-step explanation:
The statement is true.
The epicenter of an earthquake can be located using at least three seismographic stations. Seismographs measure the arrival times of seismic waves, specifically the P-waves and S-waves. By comparing the arrival times of these waves at different stations, scientists can triangulate the epicenter of the earthquake.
For example, if Seismographic Station A detects the arrival of the seismic waves 10 seconds before Seismographic Station B, and Seismographic Station C detects the arrival 20 seconds later than Station B, then the epicenter would be located at the intersection of the three station locations.
