FAULTS FAULTS ARE ONE OF THE STRUCTURAL FEATURES OF ROCKS WHILE ROCKS AT OR NEAR THE SURFACE OF THE EARTH ARE COOL & BRITTLE, ROCKS BELOW THE SURFACE OF THE EARTH ARE HOT AND TEND TO MOVE
FAULTS A LOT OF EXTERNAL FORCES ACT UPON THE ROCKS AND CAUSE STRESS ON THEM DUE TO THIS STRESSES, ROCKS EITHER UNDERGO DUCTILE DEFORMATION OR BRITTLE DEFORMATION IF THEY UNDERGO DUCTILE DEFORMATION, ROCKS DEVELOP FOLDS. IF THEY UNDERGO BRITTLE DEFORMATION, THEY DEVELOP FAULTS.
FAULTS FAULT IS DEFINED AS A SPLIT OR CRACK OR FRACRTURE IN THE ROCK PRESENT IN EARTH’S CRUST CHARACTERISED BY RELATIVE DISPLACEMENT OF ONE SIDE OVER THE OTHER.
ELASTIC REBOUND THEORY The elastic rebound theory is an explanation for how energy is spread during earthquakes. As plates on opposite sides of a fault are subjected to force and shift, they accumulate energy and slowly deform until their internal strength is exceeded. At that time, a sudden movement occurs along the fault, releasing the accumulated energy, and the rocks snap back to their original undeformed shape.
