Question

The S-P Interval of seismic waves recorded at a seismometer in eight minutes. Approximately how far away is the earthquakes epicenter from the seismometer? [equation: (S-P interval)= 0.00146 (distance to epicenter)]

A. 5,500
B. 8 km
C. Less than 1 km
D. 550 km

Answer 1

The distance from the earthquake epicenter from the seismometer is a) 5,500.

Step-by-step explanation:

The equation is given by the S-P interval of 8 minutes = 0.00146 * distance to epicenter. The distance to epicenter is equal to 5500. The lower the interval of seismic waves, the closer it is to the epicenter.
