Base your answer to the next question on the seismogram below. The seismogram was recorded at a seismic station and shows the arrival times of the first P-wave and S-wave from an earthquake. Which part of this seismogram is used to find the distance to the epicenter of the earthquake?

• S-wave arrival time, only

• P-wave arrival time, only

• Difference in the arrival time of the P-wave and S-wave

• Difference in the height of the P-wave and S-wave

What would be most effective in minimizing the potential damage caused by an earthquake?

• Installing sirens in areas prone to earthquakes
• Building structure that withstand ground vibrations.
• Increasing the amount of concrete during road building
• Requiring the recycling of metal and wood products

A minimum of ​ (a)   seismic stations are needed to determine the location of an earthquake’s epicenter.

• 3
• 2
• 4
• 5

Base your answer on the diagram below, which represents seismic stations A, B, and C. The distance from each station to an earthquake’s epicenter is plotted. The epicenter is closest to point:

The circles on the map show the distances from three seismic stations, X, Y, and Z, to the epicenter of an earthquake. Which location is closest to the earthquake epicenter?

Answer explanation

Location B is the epicenter of the earthquake. Locations A, C, and D only contain 2 intersecting circles - therefore they are not the epicenter.
