Millions Prepare for Great California ShakeOut 2025 Earthquake Drill

On the morning of March 16, 2025, millions across California will participate in the 17th annual Great California ShakeOut earthquake drill. This event aims to enhance preparedness for a potential significant earthquake, specifically simulating a massive 7.8-magnitude quake on the southern San Andreas Fault.

At precisely 10:16 a.m., participants—including residents, students, and office workers—will perform the “drop, cover, and hold on” technique. This one-minute drill is designed to educate individuals on the necessary actions to take during an earthquake and how to prepare for such an emergency.

Raising Awareness and Preparedness

According to the ShakeOut website, the drill is vital as it addresses the unavoidable reality of earthquakes in California. “It’s not a matter of if an earthquake of this size will happen — but when,” the website states, emphasizing the importance of readiness. Currently, over 10.3 million Californians have registered to take part in this year’s drill, including approximately 3.4 million in Los Angeles County and 850,000 in Orange County.

The initiative was first launched in 2008 and has gained momentum over the years, with nearly 10.4 million participants last year. Major cities in Los Angeles and Orange counties, as well as most elementary and high school districts, have joined the effort, highlighting the community’s commitment to disaster preparedness.

Organizers stress that the exercise is crucial to limit loss of life and property in the event of a significant seismic event. “Unless we take action today, there will be major losses of life and property,” they stated. The ShakeOut serves to not only raise awareness but also to equip Californians with the knowledge to respond effectively to future earthquakes.

Potential Impact of a Major Earthquake

The U.S. Geological Survey indicates that a 7.8-magnitude earthquake could result in over 1,800 deaths, 50,000 injuries, and more than $200 billion in damages. Such a quake could produce extensive shaking for at least two minutes and disruption lasting much longer. The ShakeOut drill serves as a proactive measure to prepare individuals for these potential outcomes.

Experts recommend that Californians be prepared to be self-sufficient for at least 72 hours following a major disaster. This includes having essential supplies such as a first-aid kit, medications, food, and sufficient water—approximately one gallon per person per day. Homeowners and renters are also advised to learn how to turn off gas supplies in their residences to prevent leaks.

As the Great California ShakeOut approaches, communities across the state are gearing up for this critical exercise. By participating, Californians can foster a culture of preparedness, ensuring that they are ready to face the challenges that a major earthquake may bring.
