On Tuesday, a preliminary magnitude 4.1 earthquake struck near the city of Corona in Riverside County, according to the U.S. Geological Survey (USGS). The quake, originally reported as a magnitude 4.5, occurred at 1:49 p.m., just 5.3 miles from Corona.

Residents in the Riverside area reported feeling a quick jolt, while viewers in Orange County noted shaking as well. One individual in Santa Ana described experiencing a strong shake. Fortunately, there have been no immediate reports of damage or injuries.

In response to the earthquake, the Los Angeles Fire Department briefly activated its "earthquake mode." This involved members from all 106 stations across the city surveying their respective coverage areas for any signs of damage. However, no significant issues were found.

Tuesday's earthquake was part of a sequence of smaller tremors occurring in the same region. According to Seismologist Dr. Lucy Jones, there were several earthquakes on Tuesday, the largest of which measured 2.8, with a total of approximately a dozen reported. Dr. Jones explained that this indicates a sequence, where one earthquake increases the likelihood of another occurring, usually remaining small.

Dr. Jones added that the 4.1 magnitude earthquake has a 5% chance of being followed by a larger seismic event within the next few days.

The USGS plays a vital role in monitoring earthquake activity in California, providing useful information to residents and promoting preparedness efforts. While this earthquake was relatively moderate in magnitude, it serves as a reminder to remain vigilant and have emergency plans in place.

As seismic activity continues to be closely observed, residents are encouraged to stay informed about safety procedures and make the necessary preparations to minimize potential risks associated with earthquakes.
