The Philippine fault zone (PFZ) is a major tectonic feature that transects the whole archipelago and poses high seismic risk. This web page shows the large-scale digital mapping of the PFZ based on aerial photograph interpretation and satellite images.
A fault is a fracture or zone of fractures between two blocks of rock that move relative to each other. Learn about different types of faults, such as normal, reverse, strike-slip, and oblique-slip, and see animations and examples.
Jul 12, 2018 · A fault line is a fracture on the Earth's surface where rocks have moved due to stress and strain. Learn about the types, mechanisms, examples, and impacts of fault lines on human life and the environment.
Learn about the three types of faults and how they cause earthquakes, with examples from the San Andreas Fault. Find out how rock deforms and rebounds elastically under stress, and how this explains the elastic rebound theory.
The two colorful ridges (at bottom left and top right) used to form a single continuous line, but have been split apart by movement along the fault. In geology, a fault is a planar fracture or discontinuity in a volume of rock across which there has been significant displacement as a result of rock-mass movements.
Learn how the earth's crust moves, cracks, and shakes in this interactive exhibit. Explore the science of plate tectonics, faults, waves, and measurements of earthquakes.
