Are fault lines dangerous?
Major active faults such as the Hayward Fault are associated with many hazards. The most obvious hazard is that of large earthquakes, which induce ground shaking over a large area that can cause heavy objects to fall and windows to shatter, and can cause structural damage to buildings and bridges.
How far from house is safe from fault?
Phivolcs now recommends avoiding construction within 5 meters on each side of a fault trace, or a total width of 10 meters.
Why do people live along fault lines?
Millions of people now live atop fault lines because long ago small communities gathered at fresh water sources. It is the fault that provides the water, but the fault may kill you when it moves.
What major cities are on fault lines?
The World’s Most Earthquake-Prone Cities
- Tokyo, Japan. When accounting for overall exposure to the five major natural catastrophes (river floods, earthquakes, wind storms, storm surges and tsunamis) Tokyo remains first.
- Jakarta, Indonesia.
- Manila, Philippines.
- Los Angeles & San Francisco, United States of America.

How does the San Andreas Fault affect humans?
Yet in an instant, that crack, the San Andreas fault line, could ruin lives and cripple the national economy. In one scenario produced by the United States Geological Survey, researchers found that a big quake along the San Andreas could kill 1,800 people, injure 55,000 and wreak $200 million in damage.
Is it important to know the effects of bending of rocks along faults Why?
Answer. The bending of rocks along faults causes the snapping of the faults causes the snapping of the faults because of loss of friction that holds the fault planes together in place.
What happens when the rock bending becomes too much?
Answer: If a rock bends and stays bent after stress is released, it is said to undergo plastic behavior. A combination of elastic and brittle behavior causes earthquakes. Rocks get bent in an elastic fashion until they reach their limit, then they break in brittle fashion.
