Southern California residents were rattled awake Thursday morning as a magnitude-4.7 earthquake struck north of Malibu. What followed were dozens of aftershocks that shook parts of the Los Angeles County coast and inland areas. Though the quake caused no major injuries or damage, it’s a stark reminder of the seismic activity in the region.
The Earthquake Breakdown
At precisely 7:28 a.m., the quake, initially reported as a magnitude-5.1 but later revised to 4.7, struck at a depth of about seven miles. Residents in Malibu, Santa Monica, Hermosa Beach, the Hollywood Hills, and even parts of Anaheim felt the ground tremble. According to the U.S. Geological Survey (USGS), this was a shallow earthquake, making it more likely to be felt over a broader area.
For many, the shaking was a wake-up call, quite literally. Mark Little, a resident of the area, described the quake as lasting longer than previous tremors: "The shudder and the shake were more severe this time around."
Aftershocks: A Continuing Saga
Following the initial quake, more than two dozen aftershocks were recorded, including two with a magnitude of 3.4. These aftershocks add to a growing list of small tremors that Southern California has experienced in recent weeks. Seismologists, including Dr. Lucy Jones, noted that while none of the recent quakes have been damaging, they serve as a reminder that the region’s seismic activity is far from dormant.
“We are having earthquakes. None of them have been damaging. They’ve all been small,” Dr. Jones said. "This is a really good reminder that the quiet of the last couple of decades is not our long-term picture."
How Prepared Is Southern California?
Despite the region's notorious earthquake activity, Southern California has been fortunate in avoiding significant damage recently. Los Angeles' Metro system took immediate precautions, slowing down trains to check for any potential structural damage. Such measures are standard procedure following quakes of this magnitude.
But for local business owners like Scott Richter of Scott’s Malibu Market, it was a nerve-wracking moment. Richter, who was on his way to work, saw his store’s security camera footage later, which showed his employees grasping furniture as the store shook during the early morning earthquake.
"It’s part of living in Malibu," said Richter. "You learn to expect these things, but you can never fully be prepared."
Stay Alert: Tech to the Rescue
In a region prone to earthquakes, preparedness can save lives. One valuable tool is the MyShake app, which sent over 425,000 alerts to smartphones across the region. The app is part of California’s early warning system, designed to give residents a few seconds’ notice before shaking begins.
These brief moments can make a significant difference, allowing people to take cover or move away from windows and falling objects. Such technology, combined with general earthquake awareness and preparedness, is vital for Californians living in a seismically active area.
A Wake-Up Call for Southern California
While Thursday’s Malibu quake didn’t cause any significant damage or injuries, it is a sobering reminder of what Southern California could face in the future. Residents and officials must remain prepared for larger events, as the quiet period of the past few decades may not last forever.
Living in Southern California means living with earthquakes. However, the MyShake app and other preparedness measures can help residents stay one step ahead. The best defense against the next big quake is readiness — staying informed, securing your home, and knowing what to do when the ground starts shaking.
Conclusion
While this latest earthquake north of Malibu may have left many Southern Californians feeling uneasy, it also reinforces the importance of readiness in a seismically active region. From the MyShake app to Metro’s safety protocols, it's clear that being prepared is the key to navigating these natural events. Stay safe, stay prepared, and remember that these tremors are a normal part of living in earthquake country.
