Chapter 438 Good luck or bad luck?

“据中国地震台网测定，22日0：28分，在东沙群岛附近东沙岛以南（北纬20度55分，东经116度53分）发生6.1级地震，震源深度10千米。”

Not long after twelve o'clock in the evening, news of an earthquake suddenly hit the headlines of major news platforms.

Many netizens who haven't slept have paid attention to this sudden earthquake news, but they just glanced at it and stopped paying attention.

It's not that everyone is big-hearted, but this earthquake is hundreds of kilometers away from the coast, and the magnitude of the earthquake is not particularly large.

People who saw the news didn't pay much attention to this matter, let alone Li Lijian and Li Xian who didn't see the news.

Although the research ship and the supply ship were on the sea near the earthquake center, most of the people on the two ships were asleep except those on duty. Naturally, no one knew that the earthquake happened around them.

Some people said that the earthquake happened right next to them, how could the people on the two ships not feel it.

The reason is that the earthquake happened on the bottom of the sea, and Li found that they were on the surface of the sea.

There are two types of seismic waves, transverse waves and longitudinal waves.

Transverse waves propagate slowly and can only propagate in solids, while longitudinal waves travel faster and can propagate in substances in three states: solid, liquid, and gas.

Therefore, when an earthquake occurs, generally speaking, people will first feel the up and down bumps, and then shake from side to side.

But this situation is on land. If the earthquake occurs at sea, the situation is a little different.

Because transverse waves cannot propagate in seawater, people at sea can only feel longitudinal waves.That is to say, the vibrations felt when an earthquake occurs are only the impact of longitudinal waves.

The up and down vibration caused by the longitudinal wave impact is similar to the feeling of the ship bumping caused by the usual wind and waves.

Therefore, only when the magnitude of the earthquake is large and the impact force of the longitudinal wave reaches a certain level, people on the ship can feel as if they have hit the rocks.

Otherwise, people on the sea will rarely feel ocean earthquakes, unless it is a major earthquake.

Just when everyone didn't care about the earthquake warning just now.

Multiple platforms on the Internet and relevant departments in reality have reposted the tsunami level IV warning (blue) issued by the National Marine Forecasting Station.

“在东沙群岛附近东沙岛以南（北纬20度55分，东经116度53分）发生6.1级地震，震源深度10千米。

The monitoring results of the National Marine Forecasting Station show that the earthquake has triggered a regional tsunami near the epicenter.

"It is expected that the tsunami wave will reach the eastern coastal cities of Southern Guangdong Province around 22:3 on the 00nd, with a wave height of about 0.5 meters.

"The National Ocean Forecasting Station will pay close attention to the follow-up monitoring situation and release information in a timely manner."

Everyone was dumbfounded when they saw the tsunami warning.

Blue Tsunami Warning!

Why is there a tsunami all of a sudden?

Although our coastline is long, tsunamis rarely occur in the sea around us.

Will there be some earthquakes in the surrounding area, but the occurrence of tsunamis actually requires many conditions.

Marine earthquakes are very likely to cause faults in the seabed, which can cause tsunamis, but many times they do not generate tsunamis.

Normally, earthquakes with magnitudes above 6.5 are prone to tsunamis, and earthquakes with magnitudes below 6.5 have small energy and are not powerful enough to generate tsunamis.

Even if there are some higher-than-normal swells, they won't cause much damage to the coast.

Now an earthquake with a magnitude of only 6.1 actually produced a tsunami, which is amazing.

Only Baodao and Hainan Island have a higher probability of being damaged by tsunamis.

Baodao is facing the Pacific Ocean in the east, and the sea water in the east is very deep. The energy attenuation of tsunami wave propagation is very small, and the frontal islands are blocked. The transoceanic tsunami that occurs in the Pacific Ocean and other oceans will quickly spread to Baodao without any hindrance. The coast of the island caused damage to the coastal cities.

There are strings of islands and hidden reefs surrounding most of the sea area on the mainland side, forming a natural barrier against tsunamis.

Moreover, there is a continental shelf in the surrounding sea area, and the friction between the tsunami wave and the bottom of the continental shelf will cause the energy of the tsunami wave to propagate to the coast of the continent to attenuate a lot.

Therefore, cities along the coast of my country's mainland are rarely hit by transoceanic tsunamis. Generally speaking, they are local tsunamis caused by offshore earthquakes, and generally speaking, the destructive power is very small.

This blue tsunami warning made people in coastal cities in southern Guangdong Province suddenly confused.

Some old people have lived for decades and haven't encountered a tsunami yet.

But after ten minutes or so, everyone was relieved again, and went to do what they should do.

A tsunami of about 50 centimeters, for those who often live by the sea, they really don't feel it at all.

Generally, the waves caused by the landfall of a more powerful typhoon are several meters or even ten meters high.

This 50cm tsunami is really dwarfed by the big one.It's just that they were confused by the sudden tsunami warning just now and didn't react.

At this time, Cao Wen also received news of the earthquake and tsunami.

"This...what's the matter?"

Cao Wen looked at his assistant with an expression of disbelief, followed by another wry smile.

"Little Hao...his luck is beyond words.

"I said he was lucky, but the typhoon, earthquake and tsunami all found him. I said he was unlucky... Forget it, his performance all the time, it's no wonder he was unlucky."

Seeing his helpless look, Cao Wen's assistant smiled wryly, thinking, Liu Hao is really weird!
Is he a magnet?
All the messy things go to him.

The expressions on the faces of other experts were similar to those of Cao Wen after hearing the news, and they were equally speechless in their hearts.

After a few minutes, Cao Wen sighed and dialed Liu Hao's phone number.

"Old Cao, are you insomnia?" Liu Hao was a little surprised when he received a call from Cao Wen.

"You just lost sleep. I was woken up by your kid." Cao Wen couldn't hold back his depressed mood.

Hearing this, Liu Hao's heart skipped a beat.

Did he move too much and cause something bad?
There's no reason, I've done it very carefully.

"Old Cao, what do you say?"

"There's an earthquake and a tsunami over there, you know?"

"Ah! Isn't it? Earthquake? I don't feel anything?" Liu Hao asked pretending to be surprised.

He was very depressed. If Cao Wen said so, it must have been done by himself again.

He has been using the advanced sky control technique to change the geographical environment of the seabed near the Dongsha Islands just now.

"It's strange that you can feel it at sea. The magnitude of the earthquake is not big, around 6.1. The tsunami wave is also small, and it's less than one meter on your side. It's not a big problem now, but I'm afraid there will be a bigger seabed An earthquake happened." Cao Wen explained angrily.

"It should be fine. This sea area doesn't seem to be very earthquake-prone." Liu Hao replied leisurely.

These are made by himself, so naturally there is nothing to worry about.

"Who knows what an earthquake is, you'd better get out of there quickly. It's better to go back to the shore to avoid it."

"Okay, since Mr. Cao said so, I still listen to you. But it doesn't matter if you go back to the shore. I will continue to walk north, just go faster."

Cao Wen nodded, and continued chatting with Liu Hao for a while before hanging up the phone.

"It seems that if you want to get something good, you can't make a noise."

After hanging up the phone, Liu Hao habitually scratched his temple.

"Then ignore it, speed up, anyway, everyone is paying attention here."

Speeding up doesn't mean he's going to make big moves, it just speeds up.

Liu Hao's original purpose was to turn Dongsha Atoll into a real island, not an atoll.First of all, he will slowly raise all the places in Dongsha Atoll except Dongsha Island until the entire Dongsha Atoll is several meters or even tens of meters above the sea.

In this way, Dongsha Atoll has become a real island.

Then it will become the largest island in the southern waters, covering a full 500 square kilometers.
