Answer:
Seismology is the study of earthquakes, their effects, and seismic waves. The location of an earthquake's epicenter (point on the earth's surface directly above the location of rupture or faulting) can be determined using information about two of these seismic waves.
Explanation:so easy
The waves created by an earthquake are used in determining the location of the earthquake
The distance of the epicenter from the seismogram is 3,000 km
The reason the given distance of the epicenter of the earthquake from the seismogram is correct is as follows;
The given parameter is as follows;
The P-S wave interval = 5 minutes
Required:
To find the distance of the epicenter
Solution:
The relationship between P-S wave interval and distance of the epicenter, is 1.5 minutes = 900 km
Therefore, given that the P-S wave interval, we have;
1.5 minutes = 900 km
The distance of the epicenter from the seismogram, d, given that the P-S interval is about 5 minutes, is given as follows;
[tex]d= \dfrac{900 \ km}{1.5 \ min} \times 5 \ minutes = 3,000 \ km[/tex]
Therefore;
The distance of the epicenter from the seismogram, d = 3,000 km
