The 5th Annual Preparedness Expo is proud to introduce the world’s biggest mobile earthquake simulator, THE BIG SHAKER! This 24’ long 8,000 lb. hydraulic trailer realistically demonstrates an earthquake up to 8.0 magnitude! Earthquakes are the most likely natural threats for SLO County residents, and this simulator recreates conditions similar to those that would be experienced in a typical SLO County home during an earthquake. The Big Shaker will be on site shaking things up and educating the public about the importance of securing items and other elements of earthquake safety. The best defense is to be prepared!
