An earthquake registering 3.2 on the Richter scale rattled the San Francisco Bay area on Saturday. The full effect of the earthquake was felt in Berkeley. No injuries or damage were reported. This is the fourth earthquake felt in the area in the past month, leading geologists to theorize that more – and possibly larger – quakes may be in the offing.

Meanwhile, a larger earthquake shook Oklahoma and neighboring states Saturday night. The epicenter was felt about 50 miles from Oklahoma City, and is the third in the area in the past month. No injuries or damage was reported.
