A geologic fault might only be identified through detailed trenching studies, where geologists excavate a pit to examine the layered soil displaced by ancient earthquakes. The Study and Identification Process.
Earthquake Fault Definition Dip Slip Types and Their Movement Mechanisms
Surface Faults An earthquake fault definition distinguishes between the subsurface reality and the surface expression. This lateral movement can cause devastating horizontal ground shaking and surface rupture.
At the surface, however, the evidence might be subtle. The fault zone itself extends deep into the crust and can be hundreds of meters wide, filled with crushed and fractured rock known as fault gouge.
Earthquake Fault Definition Dip Slip Types and Their Movement Mechanics
Classification of Fault Movement Not all faults move in the same manner, which is why a detailed earthquake fault definition includes specific classifications based on the direction of slip. Within this category, the normal fault occurs when the hanging wall drops down, typically associated with extensional forces pulling the crust apart.
