What are the main characteristics of an earthquake?
How much do you feel an earthquake?
- The degree to which you feel an earthquake depends on the size of the earthquake (measured in magnitude) and where you are at the time. When an earthquake occurs not all the damage is cause directly by the earth moving.
How do you identify earthquake prone areas?
- 3. Earthquake prone areas are generally well identified and well known on the basis of geological features and past occurrences of earthquakes. 4. Major effects arise mainly from ground movement and fracture or slippage of rocks underground.
What is the smallest size earthquake that can cause damage?
- In Australia, earthquakes with magnitudes of less than 3.5 seldom cause damage, and the smallest magnitude earthquake known to have caused fatalities is the magnitude M w 5.4 (M L 5.6) Newcastle earthquake in 1989.
