What question can scientists learn from a seismograph reading?

• How deep is the earthquake?

• How strong is the earthquake on the Richter Scale?

• How far away will the earthquake travel?

• How much damage will the earthquake cause?

The seismograph is most useful for studying earthquakes because...

• it can predict the weather.

• it can prevent an earthquake.

• it can measure the strength of vibrations.

• it can change the intensity of an earthquake.

Scientists place several seismographs along a mountain chain. Which question will the scientists MOST LIKELY answer with information they collect from the seismographs?

• Where do faults occur?

• How tall are the mountains?

• How can earthquakes be prevented?

• Which parts of the mountains are formed by volcanic eruptions?

A teacher is planning a school-sponsored trip to California. The teacher knows that there are many fault lines in California. What question might she ask to ensure it will be safe to go on the trip?

• What do the most recent seismograph reports say about the vacation destination in California?

• What systems are developing in the Pacific Ocean according to satellite imagery?

• How do GIS maps help us understand the land in California better?

• What infrared images are available to help us see when earthquakes have happened in previous years?
