LOS ANGELES, Dec. 29 (UPI) -- Two medium-sized earthquakes rattled northern and southern California Tuesday, within 15 minutes of each other, officials said -- putting emergency personnel on alert in a region famously susceptible to tectonic activity.
The first earthquake, measured at a magnitude of 4.9, occurred off the northern California coast at 5:35 p.m. local time Tuesday. The epicenter was recorded about 60 miles northwest of Eureka, the San Francisco Chronicle reported.
