Earthquakes and Associated Measuring Devices

Every year about 120 strong earthquakes with magnitudes of 6 to 6.9 on the Richter scale shake different areas of the United States. But the highest level of damage is from about 18 major earthquakes that happen every year with magnitudes of 7 to 7.9 on the Richter scale.

Scientists continuously record and locate the center of all earthquakes and are trying to find a pattern that may help them to forecast earthquakes days in advance.

Many different measuring devices and equipments are used for this purpose.

Material and instructions
Learn about different types of earthquakes and how are they measured. You may optionally build a model of a Seismograph for this project. Also explain how you can use a seismograph to locate the center of an earthquake.
