The Rotary Club of Redlands was honored to welcome Jenny Bierma, Health and Safety Specialist & Training Coordinator with Flatiron Dragados, as our guest speaker. With over 20 years of experience in aviation, construction, and safety management, Jenny shared valuable insights into earthquake preparedness in California.
Why Earthquake Preparedness Matters in California
Did you know California experiences about 10,000 earthquakes every year—that’s an average of 27 earthquakes per day? While most are too small to feel, larger quakes are part of our reality.
- Alaska ranks #1 in the number of earthquakes, but California is #2 and considered the #1 state at risk due to population density and infrastructure.
- On average, California experiences a 6.0+ magnitude quake every 2–3 years, and a 7.0+ magnitude quake every 10–15 years.
- Scientists estimate there’s a 1 in 3 chance that a major earthquake will hit California within the next 30 years.
The Great ShakeOut Drill
Jenny emphasized the importance of participating in The Great California ShakeOut on October 16, 2025 at 10:16 a.m. This annual statewide drill helps individuals, families, schools, and organizations practice earthquake safety.

Myths vs. Reality
Jenny debunked some common earthquake myths and shared practical safety advice:
-
Myth: Stand in a doorway for safety.
Reality: This is outdated advice from the days of adobe homes. The safest action is to Drop, Cover, and Hold On. -
Myth: Earthquakes cause most injuries.
Reality: Many injuries come from falling objects, tripping, or panicking during shaking. Staying calm and protecting yourself is critical. -
Myth: Shouting for help is best if trapped.
Reality: Save your energy, avoid inhaling dust, and instead bang on walls or pipes so rescuers can hear you.
Preparation Tips
Jenny stressed that the best defense is preparation:
- Secure and anchor heavy items in your home.
- Stock up on two weeks’ worth of food, water, medication, and sanitation supplies for each person—and don’t forget your pets.
- Prepare for aftershocks, which can be as dangerous as the initial quake.
- After a quake, text instead of calling—cell services will likely be overloaded.
Did You Know?
A 1-point increase in magnitude equals 30 times more energy released. For example, a 7.0 is 30 times stronger than a 6.0 quake.
Earthquakes are a part of life in California, but with preparation and awareness, we can reduce risks and protect our families and communities.
