California's largest lake, the Salton Sea, was created by accident in 1905 and was transformed into a vacation location by developers who built up the shoreline with resorts, hotels, yacht clubs and more. By the 1950s, thousands flocked to vacation there, including celebrities like Frank Sinatra and The Beach Boys. At one point, it was the most visited destination in the state - beating out Yosemite National Park. During the 1950s and 60s, celebrities flocked to the area to kick back and relax with some fun in the sun for vacations. Eventually, developers and officials saw an opportunity to bring tourism to the area so they began building fancy properties and yacht clubs around the Salton Sea.

Scientists believe its only a matter of time before a devastating earthquake hits southern California. The'Big One', expected to be triggered by the San Andreas fault, could leave thousands dead or displaced. Now, scientists are preparing for the worst - and the latest defence is a steel frame building that experts believe could withstand a major tremor. Researchers at the University of California in San Diego rocked and rattled a six-story steel frame building on a giant shake table to see how the structure would withstand major earthquakes. The shaking simulated an earthquake of the 6.7 magnitude that occurred in 1994 in Los Angeles, causing significant damage.
