California's first recorded earthquake may have been the largest in the history of the Los Angeles basin and powerful enough to raise the Orange County shoreline more than 11 feet in some places, UC Irvine researchers say.

On July 28, 1769, Spanish explorer Gaspar de Portola and his men lay encamped on the banks of the Santa Ana River in what is now north Orange County. They felt a violent earthquake, followed by a number of aftershocks over the next several days. The Spanish measured the length of the shaking by the number of Hail Marys they could utter.
