Question

The S-P interval of seismic waves recorded at a seismometer is 8 minutes. Approximately how far away is the earthquake’s epicenter from the seismometer? [equation: (S-P interval) = 0.00146 (distance to epicenter)]
a.8 km b. 550 km c. 5,500 km d. less than 1 km 12.

Answer 1

According to the equation the correct answer with the interval registered in minutes is: C
8=0.00146 (distance to epicentre) <=> distance to epicentre=8÷0.00146 <=>5479,45 km

Answer 2

The correct answer would be 5,500!!
