A magnitude 3.87 earthquake struck the Malibu area on March 17, 2025, at approximately 10 km northwest of Malibu, California, at a depth of 14.38 km. The quake was centered at coordinates (34.0673332, -118.8953323) and occurred at 8:17 p.m. local time 3.
Shaking Felt Across Southern California
The earthquake caused weak to light shaking in various parts of Los Angeles and Ventura counties, including Malibu, Agoura Hills, Thousand Oaks, Camarillo, and South Bay communities 3. Residents reported moderate shaking, with some describing the experience as noticeable and long-lasting enough to prompt them to seek shelter under door frames 1.
Emergency Response and Infrastructure
Emergency services were quickly activated in response to the quake. The Topanga Coalition for Emergency Preparedness (TCEP) reported that while there were no immediate reports of injuries or structural damage, the quake did lead to road closures and disruptions in the affected areas. Topanga Canyon Blvd, N. Topanga Canyon Blvd, and S. Topanga Canyon Blvd were all closed due to mudslides and other hazards 2 5. Pacific Coast Hwy was also closed to residents, with only emergency vehicles and public utility vehicles allowed passage 2.
Humanitarian Challenges and Preparedness
The recent earthquake is part of an ongoing pattern of seismic activity in the Malibu area. In 2024, California recorded 15 earthquakes of magnitude 4 or higher, the most in 65 years, with two striking Malibu 1. This increased seismic activity underscores the ever-present risk of earthquakes in the region. Residents are advised to prioritize earthquake preparedness, ensuring resilience in the face of unpredictable seismic events 1.
Earthquake Preparedness and Insurance
Given the risk of earthquakes, it is crucial for residents to consider earthquake insurance. Homeowners' insurance policies typically do not cover earthquake damage. The probability of a significant earthquake in the Los Angeles area is high, with a 60% chance of a magnitude 6.7 earthquake in the next 30 years 1. GeoVera, a premier provider of residential earthquake insurance, emphasizes the importance of securing earthquake insurance to protect against potential losses 1.
Community Response and Support
The community has come together to support those affected by the earthquake. The Topanga CERT (Community Emergency Response Team) is actively involved in providing assistance and coordinating relief efforts. Residents are encouraged to reach out to local emergency services and community organizations for support 2 5.
