The records in seismograph A show that the interval between the arrival of P waves and S waves is 5 minutes. On the other hand, records in the seismograph B indicate that the interval between the arrival of the waves is 15 minutes. In this case, seismograph A is closer to the earthquake's epicenter.

P waves at station A arrived at 6:05 pm, while the S waves arrived at 6:l0 pm. The arrival of P and S waves in station A hasa time difference of 5 minutes. On the other hand, P waves at station B arrived at 6:10 pm, whereas the S waves arrived at 6:25 pm. In station B, the time difference is 15 minutes, which is greater than the time recorded in station A. Therefore, station A is closer to the Earthquake's epicenter.
