the s-p interval of seismic waves recorded at a seismometer is 8 minutes. the equation for determining this distance to the epicenter is s-p interval = 0.001613 × distance to epicenter approximately how far away is the earthquake’s epicenter from the seismometer? ○ less than 1 km ○ 8 km ○ 500 km ○ 5,000 km

the s-p interval of seismic waves recorded at a seismometer is 8 minutes. the equation for determining this distance to the epicenter is s-p interval = 0.001613 × distance to epicenter approximately how far away is the earthquake’s epicenter from the seismometer? ○ less than 1 km ○ 8 km ○ 500 km ○ 5,000 km

Answer

Explanation:

Step1: Rearrange for distance

$\text{distance to epicenter} = \frac{\text{S-P interval}}{0.001613}$

Step2: Substitute given interval

$\text{distance to epicenter} = \frac{8}{0.001613}$

Step3: Calculate approximate value

$\text{distance to epicenter} \approx 4960 \text{ km}$

Answer:

5,000 km
