Earthquakes Made History 25 Years Ago

Today marks the 25th anniversary of the Landers-Big Bear earthquakes. Still consider to be two of the strongest earthquakes ever to strike the southern California desert area and the biggest since the 1906 San Francisco quake. However, the quakes were not the deadliest.

The magnitude 7.3 Landers earthquake struck in the San Bernardino County desert east of Los Angeles shortly before 5 a.m. on June 28, 1992. Three hours later a magnitude-6.5 quake struck near Big Bear Lake in the San Bernardino Mountains.

Between the two quakes, 400 people were injured and $91 million in damages were suffered. The physical damage was also significant. The quakes triggered landslides that wiped out roads and opened a 44-mile-long rupture in the earth.

It is important to learn and practice the proper safety procedures for earthquakes, including preparing or updating emergency plans, stockpiling or replenishing water, food and other emergency supplies and securing homes.

Here are a few more earthquake preparedness tips:

  • Practice What to Do – Reduce injury by practicing ‘Drop, Cover and Hold On’ when the ground shakes.

 

  • Develop a Plan – Develop an emergency plan that includes the name and telephone number of an out-of-area contact; a place where everyone can meet if they are separated after the earthquake; and special provisions for pets, children, seniors and persons with access and functional needs.

 

  • Get Ready – Stockpile at least a three-day supply of water, food, medications and other supplies such as flashlights, battery-operated portable radios, extra batteries and other supplies.

 

  • Learn First Aid – How to treat cuts, abrasions and other injuries that are not life-threatening will enable parents and guardians to provide immediate care to their loved ones and allow emergency medical personnel to focus their attention on those with more serious and life-threatening injuries.

 

  • Secure Your Home – Make sure your home is bolted to the foundation and water heaters, entertainment centers, computer systems and other objects that could fall and cause injury are secured.  Homeowners should also contact their insurance agents to see if earthquake insurance is feasible for them.
