What does a seismograph measure?

• The amount of oil and gas underground.

• The amount of damage an earthquake causes.

• The temperature of the earth's core.

• The amount of shaking of the crust.

How does triangulation show the location of the epicenter of an earthquake?

• By scientist looking around to see where the most damage was created.

• By making triangles on a map.

• By calculating the difference between the P and S waves in arrival times and determining the distances from at least 3 seismic stations.

• By drawing 3 or more random sized circles on a map to see where they intersect.
