Los Angeles, a city perched on a web of active faults, was jolted by Los Angeles Earthquakes 2025 on July 31, when a magnitude 4.3 quake struck near Rialto, rattling the Inland Empire, Los Angeles, and Orange counties. Southern California’s seismic surge—15 sequences of magnitude 4.0 or higher in 2024, the most in 65 years—keeps the threat of the “Big One” ever-present. For Angelenos and visitors, understanding Los Angeles Earthquakes 2025 and preparing for future tremors is vital. Here’s your guide to the latest Los Angeles Earthquakes 2025, including key events, risks, and safety tips to stay ready.
Recent Los Angeles Earthquakes in 2025
Southern California’s seismic activity has intensified, with Los Angeles Earthquakes 2025 making headlines, per the U.S. Geological Survey (USGS) and Los Angeles Times:
- July 31, 2025 (Rialto): A magnitude 4.3 quake hit at 9:32 a.m. near Muscoy, San Bernardino County, 50 miles east of Los Angeles, at a depth of 3.3 miles. A magnitude 3.0 foreshock at 8:34 a.m. and a 3.1 aftershock at 9:36 a.m. followed, with at least five aftershocks by 11 a.m. Shaking reached from Los Angeles to San Diego and Ventura County, rated Intensity 4 (light) on the Modified Mercalli Scale, with no reported damage or injuries.
- June 10, 2025 (Manhattan Beach): A magnitude 3.4 quake struck at 12:15 p.m., 8.9 miles west-southwest of Manhattan Beach, at a depth of 6.84 miles. No damage or injuries occurred.
- March 9, 2025 (Malibu): A magnitude 4.1 quake hit at 1:03 p.m., 7 miles southwest of Westlake Village, with aftershocks of 2.5, 3.0, and 2.8. Light shaking was felt in Malibu, Agoura Hills, and downtown Los Angeles, with no damage reported.

These Los Angeles Earthquakes 2025 follow 2024’s active year, with a magnitude 4.7 quake in Malibu on September 12, highlighting ongoing seismic volatility.
Why Los Angeles Faces Frequent Quakes
The Los Angeles Earthquakes 2025 stem from the city’s position on a sediment-filled basin atop the San Andreas Fault and smaller faults like Puente Hills and Northridge Blind Thrust, amplifying shaking like a “bowl of jelly.” The USGS estimates a 93% chance of a magnitude 6.7 or greater quake in Southern California by 2045, with the San Andreas capable of magnitude 8 events. The 1994 Northridge quake (magnitude 6.7) killed 58 and caused $49 billion in damage, underscoring the risk of Los Angeles Earthquakes 2025.
Tsunami Risks in 2025
A magnitude 8.8 earthquake off Russia’s Kamchatka Peninsula on July 29, 2025, triggered a tsunami advisory for Los Angeles, Orange, Ventura, and Santa Barbara counties. Modest waves damaged a dock in Crescent City, but Los Angeles Earthquakes 2025 had minimal coastal impact. Near-shore tsunamis pose a greater threat, with potential 15-foot waves in Marina del Rey or Santa Monica if triggered locally.
