There is a "surprising" relationship between the water level of Southern California's Salton Sea Lake and the odds of a feared earthquake. The San Andreas fault, one of the largest in the world, has been without seismic activity for more than 300 years.
Scientists say that when the accumulated energy is released, it could have catastrophic consequences for large cities in the area, such as Los Angeles. According to the U.S. Geological Survey, there is a 60% chance that a magnitude 6.7 earthquake will shake Los Angeles in the next 30 years.
