1. FAULTS AND FAULTING Lemuel Jhon S. Libres Janice Putian Sta. Fe Lopez

4. A fracture along which there has been displacement of the sides relative to one another. -Dictionary of Geological Terms A break or planar surface in brittle rock across which there is observable displacement -n.Geology (Mining Industry terminology) a planar fracture in a volume of rock, across which there has been significant displacement -Wikipedia(The Free Encyclopedia) is a planar fracture in rock in which the rock on one side of the fracture has moved with respect to the rock on the other side - Structural Geology (web)

6. Active faults are structure along which we expect displacement to occur Inactive faults are structures that we can identify, but which do no have earthquakes Reactivated faults form when movement along formerly inactive faults can help to alleviate strain within the crust or upper mantle

7. Dip-slip movement occurs when the hanging wall moved predominantly up or down relative to the footwall. Strike-slip,the hanging wall moves horizontally Oblique-slip,the hanging wall motion is neither dominantly vertical nor horizontal

8. Stress is a force per unit area or a force that acts on a surface. Strain is a measure of material deformation such as the amount of compression when you squeeze or the amount of elongation when you stretch something Friction is a stress which resists motion and acts in all natural systems
