A magnitude 3.5 earthquake rattled the Los Angeles County coastline Sunday night, prompting reports of shaking from residents across the region. The U.S. Geological Survey (USGS) reported the quake occurred at 9:40 p.m. Pacific Time, approximately 13 miles from Rancho Palos Verdes.
The tremor was felt across a wide area, including the city of Los Angeles, located 13 miles from the epicenter, as well as Palos Verdes Estates, Rolling Hills Estates, and Avalon on Catalina Island, all roughly 14 miles away. While initial reports indicate moderate shaking, no immediate reports of damage or injuries have been confirmed.
Earthquake Details and Recent Activity
According to the USGS, the earthquake struck at a depth of 6.8 miles. This relatively shallow depth often contributes to stronger shaking at the surface. In the past 10 days, the area has experienced one other earthquake of magnitude 3.0 or greater, indicating ongoing seismic activity in the region. You can report your experience to the USGS here.
Southern California is located in a seismically active zone, and earthquakes are a common occurrence. On average, the Greater Los Angeles area experiences around five earthquakes with magnitudes between 3.0 and 4.0 each year, based on a three-year data sample from the USGS. While a magnitude 3.5 earthquake is not considered major, it can be felt by many and serves as a reminder of the region’s earthquake risk.
Preparedness Resources for Southern California Residents
Given the potential for larger earthquakes in the future, experts emphasize the importance of preparedness. The Los Angeles Times offers a six-week newsletter, “Unshaken,” designed to help residents prepare for a major seismic event. The newsletter covers essential topics such as building earthquake kits, identifying useful mobile applications, and incorporating advice from seismologist Lucy Jones.

Earthquake preparedness includes securing your home, creating a family emergency plan, and knowing what to do during and after an earthquake. Resources are available from the USGS and local emergency management agencies to help residents develop a comprehensive preparedness strategy.
