Northern California Residents Awakened by 4.6 Magnitude Earthquake
An earthquake with a magnitude of 4.6 struck Northern California early Thursday morning, causing residents to feel their homes shake across a 100-mile stretch, including San Francisco. The U.S. Geological Survey reported the earthquake was centered near Boulder Creek in the Santa Cruz Mountains. Despite the widespread shaking, there were no immediate reports of serious damage. Boulder Creek, a town with approximately 5,000 residents, is located about 65 miles southeast of San Francisco. The tremor was felt as far north as Petaluma, 40 miles north of San Francisco. Over 25,000 impact reports have been filed with the survey, indicating the widespread nature of the event. Robert de Groot, a physical scientist with the U.S. Geological Survey Earthquake Science Center, noted that while such magnitude earthquakes are not frequent, they serve as reminders of California's seismic activity.
