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

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

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.
