Tsunamis are waves of sea water triggered by earthquakes, volcanic eruptions, landslides on land or under the sea or the fall of a meteor. These waves can move at very high speeds and reach land with a height of up to 30 meters.

Natural disasters such as tsunamis can take lives because people do not have time to save themselves, causing damage to facilities and infrastructure.

So, is there a way to do when facing a tsunami ?

Before a tsunami occurs, there are generally natural signs, for example, large and long-standing earthquakes, receding sea water to show coral and fish, or the rumbling from the middle of the ocean.

If you see these signs, immediately look for information, both about the earthquake, tsunami potential, to the fastest evacuation route to higher ground.

Then, if you manage to survive after an earthquake with high strength, you should immediately go to a high place to take shelter for a while.

🔹Do this even though an official tsunami warning has not been issued.

"You cannot wait for the authorities if a significant earthquake occurs and you live near the coast," said Denis Chang Seng, technical secretary for the UNESCO Intergovernmental Coordination Group for Early Warning and Tsunami Mitigation Systems in the Northeast Atlantic, Mediterranean and Sea connected to it.

Immediately save yourself, especially after a large earthquake that might have an impact on your home. No need to try to spruce up the condition of the house. Beware of aftershocks.

When saving yourself, make sure you are not tempted to ride a private vehicle. Go on foot because riding a vehicle will hinder your journey.

For those of you who are evacuating using a vehicle and a traffic jam occurs, immediately lock and leave the vehicle. Continue evacuation by walking to the highest place.

"If you are six feet above sea level, don't stop, keep moving up," said Ian Miller, an expert on coastal hazards at the Washington Sea Grant.

In addition to moving towards the highlands, also pay attention to the surrounding area. Not only the beach, you also need to stay away from the river.

"Tsunamis can rise to rivers very quickly, and many people are shocked," Chang Seng said.

If possible, listen to information from the authorities via radio or other communication devices.

If you do not have time to take part in the evacuation process, try looking for sturdy reinforced concrete buildings. Climb as high as possible to the roof. Stay away from buildings and bridges that can shed heavy debris.

Keep in mind that a tsunami does not come once, but can go up to five times. Therefore, before there is an announcement from the authorities that the conditions are safe, do not leave the evacuation site because the waves that come later are often higher and dangerous.

Post-tsunami after the situation is declared safe, you will be allowed to return to their respective homes. Be aware of electrical installations and moving water because the currents can harm you.

Also avoid stagnant areas because of possible contamination of hazardous substances and the threat of electric shock. It can also make you puddle or get stuck in a hole.

Then, if possible, it is better to clean the mosquito and insect dens. Pay attention to your health and personal safety as well as your family by washing your hands with clean water and soap if you are hit by tsunami inundation water.

Next you need to do you still need to look for information or news about water conditions, as well as where to get emergency tent assistance, clothing health posts, and food.
