ACCORDING TO THIS MAP WHERE IS THE EPICENTER LOCATED?

• MIAMI

• CHARLESTON

• DALLAS

HOW LONG DID IT TAKE THE P WAVE TO TRAVEL 2000 KM?

• 2 MIN

• 4 MIN

• 6 MIN

What do you call the instrument that records and measures seismic waves?

• seismograph

• richtometer

• seismogram

• seismophone

WHAT IS THE DIFFERENCE IN TIME THAT IT TOOK AN S WAVE AND P WAVE TO TRAVEL 2,000 KM?

• 10 MINUTES

• 12 MINUTES

• 3 MINUTES

Where is the epicenter for this earthquake located based on triangulation?

• A

• B

• C

• D

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.

The location inside the Earth where an earthquake originates is the 

• earthquake

• fault

• focus

• epicenter
