A magnitude 3.5 earthquake hit at 8:31 a.m. in Willowbrook. It was felt across the region but was too small to cause any damage. It occurred just before Kamala Harris, the former California senator, was sworn in as the first female vice president.
The earthquake’s epicenter, according to the U.S. Geological Survey, was just west of Magic Johnson Park, less than a mile from Compton and a mile from West Athens. The earthquake occurred at a depth of 11.7 miles.
