State. Seismic stations A, B, and C received the data used to locate the earthquake
epicenter. The seismogram recorded
at station A would show the (NY Regents

P-waves | c. | arrival of S-waves before the arrival of P-waves | d. | greatest difference
in the arrival times of P-waves and S-waves |

was recorded at three different seismic stations, A, B,and C. Which statement correctly describes the distance between the earthquake
epicenter and these seismic stations? (NY Regents 2004) a. | C is closest to the epicenter, and A is farthest from the
epicenter. | b. | B is closest to the epicenter, and C is farthest from the
epicenter. | c. | A is closest to the epicenter, and B is farthest from the
epicenter. | d. | A is closest to the epicenter, and C is farthest from the
epicenter. |

epicenter of the same earthquake to this seismic station? (NY Regents 2006) a. | 9 min 40 sec | c. | 19 min 00 sec | b. | 6 min 40 sec | d. | 15 min 00 sec |
