A series of three earthquakes — each registering an identical magnitude of 3.2 — struck Saturday morning in the Oakland hills, beneath the Oakland Zoo, according to the U.S. Geological Survey.

The temblors began at 9:24 a.m. Saturday, with the first one occurring at a depth of about 4.3 miles underneath the zoo, nestled in the Oakland hills just outside of San Leandro and just west of Lake Chabot Regional Park, the agency reported.
