The Impact of earthquakes are different in each society and environment. There are more damages to bulidings and etc. in 3rd World countries than 1st World Countries.
If an earthquake generates a large enough intensity, structures can be severely damaged. Buildings may fall and bury anyone close by.
Landslides include a range of ground movement such as falling rocks and debris falls.
- Earthquakes create stresses that make weak slopes fail
- Earthquakes of magnitude 4.0 and greater have been known to trigger landslides
Soil Liquefaction is an event in which the strength and stiffness of a soil is reduced. Liquefaction is the mixing of sand or soil and ground water during an earthquake. This causes the soil to act like quicksand. If liquefaction occurs under or near a building, it may start to lean or sink. Liquefaction has been responsible for tremendous amounts of damage in various earthquakes.

Surface Rupture is an offset of the ground surface when fault rupture extends to the earth's surface causing any structure built upon the fault to split apart as the two sides of the fault slip past each other.
