   [[Content::PREPARE

• Learn the signs of a potential tsunami, such as
  • an earthquake,
  • a loud roar from the ocean, or
  • unusual ocean behavior, such as
    • a sudden rise or wall of water or
    • sudden draining of water showing the ocean floor.
• Know and practice community evacuation plans.
  • Some at-risk communities have maps with evacuation zones and routes.
• Map out your routes from home, work and play.
  • Pick shelters 30m or more above sea level, or at least one km inland.
• Create a family emergency communication plan that has an out-of-state contact.
  • Plan where to meet if you get separated.
• Sign up for your community’s warning system.
• Consider earthquake insurance and a flood insurance policy.
  • Standard homeowner’s insurance does not cover flood or earthquake damage

DURING

• If there are natural signs or official warnings of a tsunami, move immediately to a safe place as high and as far inland as possible.
• Listen to the authorities, but do not wait for tsunami warnings and evacuation orders.
• If you are outside of the tsunami hazard zone and receive a warning, stay where you are unless officials tell you otherwise.
• Leave immediately if you are told to do so.
  • Evacuation routes often are marked by a wave with an arrow in the direction of higher ground.
• If you are in the water, then grab onto something that floats, such as a raft or tree trunk.
• If you are in a boat, face the direction of the waves and head out to sea. If you are in a harbor, go inland.

AFTER

• Listen to local alerts and authorities for information on areas to avoid and shelter locations.
• Save phone calls for emergencies.
  • Phone systems often are down or busy after a disaster.
• Use text messages or social media to communicate with family and friends.
• Avoid wading in floodwater, which can contain dangerous debris.
  • Water may be deeper than it appears.
• Be aware of the risk of electrocution.
  • Underground or downed power lines can electrically charge water.
  • Do not touch electrical equipment if it is wet or if you are standing in water.
• Stay away from damaged buildings, roads and bridges.
• If you become injured or sick and need medical attention, contact your healthcare provider and shelter in place, if possible.
• Call the emergency call number (112) if you are experiencing a medical emergency.
• Document property damage with photographs.
• Conduct an inventory and contact your insurance company for assistance.
