Let’s discuss another natural hazard that affects every Southern California resident: earthquakes.

New Alarming Research

Yahoo News reports on new research published in the Journal of Geophysical Research: Solid Earth, suggesting that stress along Southern California’s San Andreas and San Jacinto fault systems has reached some of the highest levels in the past 1,000 years.

Researchers say stress has continued to build since the last major rupture more than 160 years ago. While scientists emphasize that this does not mean a major earthquake is imminent, the study serves as an important reminder that Southern Californians should always be prepared.

Understanding the Findings

The study examined Southern California’s interconnected fault systems, including the San Andreas and San Jacinto Faults. Researchers found that several fault segments are experiencing unusually high levels of tectonic stress.

One area receiving particular attention is Cajon Pass, where the two fault systems meet. Scientists believe this location may either stop a rupture from spreading or allow multiple faults to connect during a major seismic event. The possibility of a larger, multi-fault earthquake could intensify impacts across Southern California including right here in Calabasas.

What the Study Does Not Mean

It’s important to separate scientific facts from common earthquake myths. The San Andreas Fault is not expected to split California in two or cause any part of the state to fall into the ocean. The fault is a strike-slip boundary, where the Pacific Plate and the North American Plate slide horizontally past each other.

Even during a major earthquake, the result is lateral movement along the fault rather than the formation of a giant crack dividing California. Most earthquakes also do not produce dramatic surface ruptures that break through the ground. While some do, most occur deep beneath the surface without visible fault movement.

Preparedness Remains the Best Defense

The challenge with earthquakes is that scientists cannot predict exactly when one will occur. That’s why preparedness remains so important. At the forefront in efforts to prepare Calabasas residents is the EPIC app. The free app, available on bothAppleor Google Play as EPIC Calabasas, provides tools and information to help individuals and families prepare for and respond to emergencies. With information permanently stored on users’ phones, the app remains accessible even during power outages and loss of Internet connectivity.

The app provides step-by-step instructions and guides to become prepared. Topics that follow are all found on the app:

• Secure tall furniture, bookcases, and televisions to walls.
• Know how to shut off gas, water, and electricity if necessary.
• Keep emergency supplies accessible, including water, food, flashlights, medications, and batteries.
• Create a family communication plan.
• Store sturdy, hard-bottom shoes and a flashlight near your bed. Most earthquake injuries are to the feet, caused by shattered glass and other sharp items.
• Practice Drop, Cover, and Hold On with family members.
• Review your earthquake insurance coverage and understand what is and is not included.

Preparedness Builds Confidence

Earthquakes can happen without warning, but being prepared can make a significant difference in how individuals and families respond. Rather than focusing on what we cannot control, EPIC encourages residents to take practical steps today. A few simple actions now can improve safety, reduce stress, and help families recover more quickly when the next earthquake occurs.

Preparation is the most effective way to reduce the impact of an earthquake and prevent a serious event from becoming a larger disaster. It isn’t about fear. It’s about resilience.

Stay safe.
