False 1. Earthquake can easily be predicted by the scientist & ordinary people.

False 2. Movement of tectonic plates causes earthquake.

True 3. The focus of an earthquake is also an epicenter.

True 4. During a large earthquake, you should take cover under a sturdy table, furniture or desk.

True 5. Large magnitude of earthquakes are strong and terrifying.

True 6. Hypocenter is where the earthquake originates.

False 7. Mercalli rating of VI would indicate less damage than a rating of VIII. a

True 8. Less than 10,000 earthquakes occur in an average year.

True 9. Intensity is measured by Richter scale.

true 10. An active fault has move in the past and is not capable of producing earthquake in the future.

Moment Magnitude Scale

• Today, earthquake magnitude measurement is based on the Moment Magnitude Scale (MMS). MMS measures the movement of rock along the fault. It accurately measures larger earthquakes, which can last for minutes, affect a much larger area, and cause more damage.

The Moment Magnitude can measure the local Richter magnitude (ML), body wave magnitude (Mb), surface wave magnitude (Ms).

Earthquake Magnitude Classes

• Earthquakes are also classified in categories ranging from minor to great, depending on their magnitude. What’s the difference between a light and moderate quake?

These terms are magnitude classes. Classes also provide earthquake measurement. The classification starts with “minor” for magnitudes between 3.0 and 3.9, where earthquakes generally begin to be felt, and ends with “great” for magnitudes greater than 8.0, where significant damage is expected.
