A magnitude 5.2 earthquake struck Northern California on Friday morning, just hours after a 5.5 magnitude earthquake rattled the same area on Thursday afternoon, according to officials.
The U.S. Geological Survey (USGS) reported that the initial earthquake occurred at 4:19 p.m. PT on Thursday, with the epicenter located approximately 2.5 miles southwest of East Shore. While the San Francisco Bay Area experienced a brief jolt, no immediate reports of damage were received.
On Friday morning, the notification system was activated again as an apparent aftershock with a preliminary magnitude of 5.2 was recorded at Lake Almanor, situated about 2.5 miles southwest of East Shore.
Initially, preliminary readings indicated a magnitude of 5.7 for the Thursday earthquake; however, the USGS revised its reading to 5.5. Subsequently, several aftershocks ranging from magnitudes 2.5 to 3.8 were detected, according to the USGS.
The California Highway Patrol in Yuba-Sutter reported that the earthquake caused a disruption at their Chico dispatch center, resulting in the temporary unavailability of the 911 lines. As a temporary solution, they advised people in the region to call 530-332-1200 while they worked to resolve the issue.
East Shore, a census-designated place with a population of over 150, is located approximately 162 miles northeast of Sacramento.
