Let's get to know more about tsunamis.
Tsunami comes from Japanese, namely "tsu" which means harbor, and "nami" means wave. Literally, tsunami means big waves in the harbor or big tides in the harbor.
The Japanese call it that because the tsunami waves can only be seen and can be felt when they reach the port.
Thus, people in the earthquake area will receive a natural warning, namely the earthquake. If the community feels a strong shaking or an earthquake that swings weakly but for a long time, the community is asked to immediately evacuate.
Cause of tsunami
Most tsunamis do occur after earthquakes, especially earthquakes that are followed by dislocations or displacements of very large masses of soil or rock under sea or lake water.
Other causes of tsunamis are landslides under a body of sea water, volcanic eruptions under the sea and volcanoes on an island, ocean earthquakes, or meteor strikes at sea.
If a tsunami occurs
If the sea water recedes from normal limits, a tsunami is likely to occur. Don't panic, but stay alert. Do not also make the tsunami waves as a spectacle. If the tsunami waves can be seen, it means we are in a dangerous area. Here's what to do:
Move quickly to higher ground, invite your family and people around you to participate
Stay in a safe place until the sea water completely recedes
If you are on the seafront or near a river, immediately run as hard as you can to higher ground
If possible, run to the nearest hill
If the situation allows, go to the designated evacuation place
If the situation does not allow for the above actions, look for a ferroconcrete building, use the emergency stairs to get to the top floor, at least to the 3rd floor.
