A preliminary magnitude 4.9 earthquake struck the Barstow area on Monday afternoon, causing significant shaking throughout a large portion of Southern California. The quake, which occurred at 1 p.m. local time, was initially reported by the U.S. Geological Survey (USGS).

According to the USGS, the earthquake originated at a depth of approximately six miles. The impact of the tremor was felt as far as Calabasas, Los Angeles, and Glendale, indicating the widespread reach of the seismic activity.

Following the main earthquake, a smaller 3.5-magnitude aftershock struck the same region a few minutes later, around 1:03 p.m., as reported by the USGS.

Dr. Lucy Jones, a renowned seismologist, provided her insights on the event, stating that the epicenter of the earthquake was near the Calico fault, which intersects with the Mojave region. She further mentioned that quakes of this magnitude are not uncommon in the Mojave Desert.

In response to concerns about the San Andreas fault, Dr. Jones reassured the public that Monday's earthquake, being more than 50 km away from the fault line, does not increase the likelihood of a significant San Andreas earthquake.

The residents of Barstow and surrounding areas are advised to remain vigilant and prepared for any potential aftershocks. It is crucial to follow safety guidelines provided by local authorities to ensure personal well-being and minimize the impact of future seismic activities.

As seismic events continue to occur in California, it serves as a reminder for residents to stay informed, have emergency plans in place, and be prepared for the possibility of earthquakes, which are an inevitable part of living in the region.

The USGS continues to monitor seismic activity in Southern California to provide necessary updates and ensure the safety of the affected population.
