Study Notes
Earthquake Measurements
- The moment magnitude scale is considered more objective and accurate.
Fault Activity
- Scientists determine if a fault is active by looking for signs of recent deformation, such as offset streams, scarps, and trenches.
- An inactive fault is characterized by a lack of recent deformation or seismic activity.
Earthquake Terminology
- The point on the earth's surface directly above the focus of an earthquake is called the epicenter.
- Intensity is different from magnitude in that it measures the effects of an earthquake at a specific location, whereas magnitude measures the total energy released by the earthquake.
- Seismographs are used to measure the strength of an earthquake.
- The underground point of origin of an earthquake is called the focus.
