Can the National Seismic Hazard Maps be used as an earthquake forecast tool for the near future? A new study says that as the Earth warms, a massive California flood gets more likely one that would swamp Los Angeles, displace millions and cause historic damage . Dr. Hubbard said the secondary faults she would be worried about triggering, though, would be those that are closer to Los Angeles, similar to one that caused the 1994 Northridge earthquake in the San Fernando Valley. The magnitude of an earthquake isnt enough to determine how much death and destruction it will cause. Earthquake scientists say that a subsequent quake that is generated one ruptured fault length away from the mainshock can be considered an aftershock. CEA earthquake insurance is easy to buy.
