The S-P interval is 39 seconds for a location. How far is that location from the epicenter?

The S-P interval is 51 seconds for a location. How far is that location from the epicenter?

The S-P interval can be used to determine the:

• Magnitude of the Earthquake's surface waves

• Number of foreshocks that occurred

• Number of aftershocks that will occur

• The distance of the seismograph from the epicenter

• The destruction that occurred to the nearest major city

Examine each seismogram to determine the approximate distance of each location from the epicenter:

• Furthest from the epicenter

• 
• Closest to the epicenter

• 
• Middle distance from the epicenter

• 

An Earthquake that occurs 200 km away and has surface wave amplitude of approximately 100 mm has a magnitude of ​ (a)  

• 5.5
• 5.0
• 8.0
• 7.5
• 6.0
• 4.7
• 6.7
• 9.2
