12. Natural Warning Signs: Sensing Tsunami

Tsunamis can be detected using human senses. Here are the recognizable warning signs of tsunami:

FEEL 

     big local earthquakes may cause tsunami

SEE

     tsunami may be precede by a rapid fall in sea level as the ocean recedes, exposing reefs, rocks and fishes on the sea bottom

     tsunami often come ashore as a wall of water and quickly flood inland

HEAR

     abnormal ocean activity, a wall of water, and approaching tsunami create a loud "roaring" sound similar to that of a train or jet aircraft

RUN

     don't wait for official evacuation orders

     immediately leave low lying coastal areas

     move inland to higher ground

     RUN if you see a tsunami

     Major earthquakes in populated areas can cause huge destruction. Buildings collapse, roads and bridges buckle and crack, and electrical and gas lines break and cause fires. If the earthquake happens in the ocean, it makes a series of huge ocean waves called tsunami which travels until it finally reaches land where it cause large flooding.

Effects of Earthquake Hazards

     Earthquakes are the most expensive natural disaster humans face. A strong earthquake in the wrong place at the wrong time can cause great financial damage and cost tens of thousands of human lives.
