Tsunami

What is a Tsunami? 
Tsunamis are huge destructive walls of water that can destroy most (not all) structures  in their path, they are caused by  earthquakes, or other types of disturbance.

How fast do Tsunamis go?
They can travel up to 500 MPH (805 KM/H),

How high can Tsunamis get?
Tsunamis can get up to 100 feet in some places of the world, but most tsunamis usually go only 30 feet high for the most part depending on where you are , they travel much slower in shallower coastal waters.

​How far inland does the water from Tsunamis travel?
The water can spread up to 10 miles inland depending on the shape and slope of the shorelines.
Steps to take BEFORE a Tsunami hits

  • You need to determine if your home is in a high risk area for Tsunamis. Specifically, you need to know your how high your house is above sea level and the distance of your street from the coast.
  • You need to be familiar with the warning signs of a Tsunami
    • These are:
    • An Earthquake or noticeable rumbling in the ground
    • A significant rise in coastal waters
    • A significant fall in coastal waters
  • Prepare an evacuation plan
    • Specifically, you need to choose an inland evacuation area with a high elevation
    • Many roads can be blocked while you are on the way to your evacuation spot, so you need to have multiple routes planned out
  • Learn how to disable water, gas, and other utilities in your house
    • Also be sure to teach your family members how to do this.
  • Be sure to be stocked up on disaster preparedness supplies and any essential medications that you or your family members may need. The most essential supplies are listed below
    • Flashlight with extra batteries
    • Portable, battery operated radios, along with extra batteries
    • First aid kit and manual
    • Emergency food and water
    • Non-electric can opener
    • Cash and credit cards
    • Durable shoes
  • If there is a reasonable possibility that you will be separated from your family members during a tsunami, form a plan for getting back together.

Steps to take DURING a Tsunami

  • Be sure to keep all lines of communication open. Make sure that you have access to a working radio or television to receive the latest information, and be ready to evacuate if needed
  • If you have to evacuate, be sure to head to an inland area that’s elevated.
  • DO NOT GO TO THE BEACH, IF YOU CAN SEE THE TSUNAMI, IT IS TOO LATE FOR YOU
  • Only return home when the authorities say it is safe.

Steps to take AFTER a Tsunami

  • Avoid entering damaged buildings, unless there’s someone in there who requires assistance. Do not move an injured person unless it’s necessary to prevent further harm to the individual.
  • When you return home, enter it carefully, as there could potentially be damage to your home. Check to make sure that there’s no live electrical wires.
  • Do not use any electrical appliances or lights until an electrician has checked the electrical system.
  • Open windows and doors to help the building dry.
  • Shovel mud while it is still moist in order to give the walls and floors an opportunity to dry.
  • Check your food supplies to make sure they’re not contaminated.
  • Test your drinking water to make sure that it is not contaminated.
  • Check your home for any gas leaks, if you smell gas, open up your windows and quickly leave. If you can, turn off the gas at the outside main valve and call the gas company from the neighbor’s home. If you have to turn off the gas for any reason, it must be turned back on by a professional
  • Look for electrical system damage. If you spot any broken or frayed wires, turn off the electricity at the main fuse box or the circuit breaker
  • Check for sewage and water line damage. If you suspect sewage lines are damaged, avoid using the toilets and call a plumber. If you suspect water lines are damaged, call the water company
