4. San Bernardino
Population: 215,213
Located above the main branch of San Andreas Fault line, San Andreas is another Inland Empire’s city in danger in case of an earthquake originating along the fault line. San Bernardino is rich with water, a rare thing in drought-stricken California. However, in case of an earthquake, this can pose a significant risk of soil liquefaction, which would greatly enhance damage caused by the disaster. The Christchurch Earthquake in 2011 is a recent reminder of how dangerous this phenomenon could be.
