Tsunami Preparedness

Tsunami PREPAREDNESS Week 2019

Although Tsunami Preparedness Week 2019, which took place from March 25-29, has passed, it's never too late to go over your family evacuation plan and update your disaster supply kits. Although Malibu doesn't face the same risk from a tsunami as from other disasters, it is important to always be prepared as a tsunami can strike any coast, at any time.

How to Find Out If a Tsunami is Approaching

1. Natural Warning

Strong ground shaking, a loud ocean roar, or the water receding unusually far and exposing the sea floor are all nature’s warnings that a tsunami may be coming. Immediately go to higher ground or inland. A tsunami may arrive within minutes and may last for eight hours or more. Stay away from coastal areas until officials announce that it is safe to return.

2. Official Warning 

Tsunami Warnings may come via radio, television, telephone, text message, door-to-door contact by emergency responders, or NOAA weather radios. Move away from the beach and seek more information. Follow all direction from emergency personnel, and use your phone only for life-threatening emergencies.

When Should I Evacuate?

Evacuation should not be automatic. Before evacuating, you should determine if you are in a hazard zone and consider possible hazards that may exist along your evacuation route. 

  • GO ON FOOT. Roads may be damaged. Remember what PCH looks like on a Saturday in July - the last place you want to be when a tsunami strikes the coast is trapped in gridlocked traffic. 
  • Move at least 90 feet above sea level. If this is not possible, move as far inland as you can.
  • If you are outside of a tsunami hazard zone, take no action. You are safer staying where you are.

Recommended Evacuation Routes

Prepare Now

Following a tsunami, even those who live outside the tsunami hazard zone could find themselves in a dire situation. PCH is vulnerable to tsunami damage, and many neighborhoods depend on PCH as their only means of egress. In other words, you might live, work, or go to school well out of the reach of even the largest tsunami, but your main transportation route may not be. 

As with any disaster, preparation is the key to survival. You should always keep on hand enough food and water to provide for you, your family, and your pets for at least 7-10 days following a disaster. Remember, in a wide-scale event, Malibu may not be the first priority for outside help. Each Malibu resident should be prepared to maintain their own livelihoods until help arrives.
