Los Angeles: A City of Faults Los Angeles, A City of Faults Matt Rieman
Effect on Infrastructure • Freeways cross faults in many locations creating potential risk. • Collapse of freeway bridges during the Northridge earthquake caused widespread recognition of the hazard.
- Faults run throughout the LA basin Blind thrust faults such as the Puente Hills fault are particularly dangerous -Skyscrapers are not designed for all possible motions and still have the potential to collapse during specific (and uncommon) motions
Another Result of Faulting • Oil can become trapped along faults • Yet seepage can also occur along faults • Tar pits- Caused by oil seeping up along a fault and degrading to asphalt
