Philippines Earthquake, Tsunami Alert News: Tsunami alert has been issued in many countries after the powerful 7.8 magnitude earthquake that hit the southern Philippines. At such times, a question often comes to people’s mind that why does the sea water suddenly recede before the arrival of tsunami? Many videos also go viral on social media, in which the sea shore suddenly appears empty for several meters. Actually, this is not a normal phenomenon but can be a big warning sign of tsunami. Know what is the reason behind the sudden retreat of the sea before the tsunami and how big an alert is this?
Why does the sea retreat before a tsunami?
Tsunamis are usually caused by major undersea earthquakes, volcanic eruptions or shifting of the sea floor. When the earth beneath the sea suddenly moves up or down, huge amounts of water are displaced. For this reason, waves with huge energy start spreading in all directions. Many times the first wave of a tsunami pulls the sea water away from the coast. Its effect is that the sea level suddenly goes down and the water retreats much further than normal. People start seeing the empty sea bottom, rocks and places that are usually under water.
This view of the sea before tsunami is not beautiful, it is a warning bell.
According to experts, if the sea suddenly starts retreating rapidly then one should not go towards the coast to see it or take photographs. This could be a sign of a tsunami coming. It has been seen in many historical incidents that people turned back to look at the sea and after a few minutes got caught in the huge waves.
Does this happen before every tsunami?
No. It is not necessary that the sea water retreats in every tsunami. Many times the first wave directly hits the shore in the form of high water. So it is not safe to just wait for the sea to recede. If a tsunami alert is issued after an earthquake or the administration gives a warning, one should immediately reach a safe place.
What to do during tsunami?
- If you are on the sea shore, immediately move towards higher ground.
- Follow official warnings and administrative instructions.
- Don’t go to the coast to watch the ocean retreat.
- Do not turn back even after the first wave, as several waves may come.
- Keep an eye on radio, mobile alerts and local administration information.
A sudden retreat of the sea before a tsunami can be an alarming sign of nature. It may look strange, but it is actually a warning of destructive waves coming in a few minutes. Therefore, in such a situation, not curiosity, but only alertness and immediate action can save life.
