Elephants at the San Diego Zoo Safari Park rushed to protect younger members of their herd when a 5.2-magnitude earthquake rocked southern California on Monday.⁣ ⁣ "Elephants have the unique ability to feel sounds through their feet," the zoo said. The "alert circle" is a "natural response to perceived threats to protect the herd.”⁣ ⁣ #elephants #earthquake #sandiego #animals #news #usnews #accuweather
