What Are The 3 Warning Signs of a Tsunami and Government Response

A tsunami is very dangerous for the communities and ecosystems in the coastline area. The huge wave can destroy the whole area because it sweeps everything away without any exceptions. Therefore, what are the 3 warning signs of a tsunami that people and local authorities should understand?

What Are The 3 Warning Signs of a Tsunami

1. A powerful earthquake

The main sign of a tsunami is a strong earthquake. The magnitude that can trigger a tsunami is above 7.0. This high magnitude occurs on the seafloor. The bigger fault under the sea may cause greater tsunamis on the coastline around the epicenter and other regions.

Thus, this powerful earthquake might occur for more than 20 seconds. This is one of the what are the 3 warning signs of a tsunami that people should be aware that a tsunami may follow. A great displacement on the seafloor is very harmful because a large volume of water has been displaced as well.

Once you feel this strong earthquake, it is very important to evacuate yourself with an emergency bag. You have to go to a higher land because a tsunami cannot go higher. A tsunami may arrive at the coastline in a few minutes. So, make sure you have enough time to prepare for self-evacuation.

2. Abnormal Sea Behavior

Living at the coastline may have a chance to see the abnormal sea behavior after an earthquake. The water at the beach is drawing back. The farther it draws, the greater the tsunami may follow. It is because of the fault on the seafloor that causes this phenomenon.

After a few minutes, the huge waves come to the coastal area as a tsunami. The wave can be multiple and the height reaches more than 1 meter. It is a rapid water movement that is very strong. The wave sweeps whatever it meets in the area that it destroys and damages everything.

Noticing this behavior as one of the what are the 3 warning signs of a tsunami could help people save themselves from this harmful disaster. The powerful wave can destroy the whole area in seconds. Going to a higher place for evacuation is the best and fastest option that everyone should do.

3. Loud Sound From The Sea

Another sign that people should be worried about is a loud sound. This sound is coming from the water that is drawing back. It is a loud rumbling noise that can be heard in the coastal area. It should be a serious warning for the people and communities to stay away from the sea.

It also means the tsunami is approaching. Since it is a critical situation, you have no time to stay still. You should hurry to a safe area, as far as possible from the coastal area. It is better if you run to a higher place like a hill that is free from any kind of buildings.

Government’s Responses to Tsunami Signs

1. Issuing an alert message

The first appropriate response from the government is issuing the alert message. This is an important warning for all people who live near the potentially affected area. This message has a strong command for people to evacuate as soon as possible because the tsunami wave is coming.

2. Turning on the sirens

The siren is part of the early warning system after the device and data center read that there is a potential tsunami coming. The sirens in the coastal area should be maintained well for this purpose. It gets everyone’s attention for those who are not with their phones. People who live near the sirens should be aware of this sign.

3. Preparing emergency plans

An emergency plan is crucial as a mitigation. The government has resources and a network to do a relief operation after the disaster. Besides a shelter, medical aid and a team are also part of the plan. To reduce panic because of EWS, the government should develop a clear evacuation route and excellent communication with the public.

What are the 3 warning signs that a tsunami above could occur anytime? The government should be accountable and responsible for people’s safety by providing them with information using an SMS broadcaster. This device could save many lives since it informs people about this upcoming disaster earlier.
