Spring and autumn are the most frequent periods of severe storm surge in the South Pacific.

Locals call this natural disaster "storm tsunami" or "tidal disaster".

The spatial extent of storm surge generally ranges from tens of kilometers to thousands of kilometers.

The time scale, or period, is about 1-100 hours, between earthquakes and tsunamis and low-frequency astronomical tidal waves.

Sometimes, however, the area affected by storm surge moves with the movement of atmospheric disturbance factors.

As a result, a storm surge process can sometimes affect one or two thousand kilometers of coastal areas, affecting the coastal area for several days!

The most terrifying thing is that the storm surge caused by a tropical cyclone will cause the coastal water level to rise sharply, and the phenomenon of seawater inflow will occur.

Historically, there have been countless small islands that have been submerged due to tidal disasters.

The west coast of Eurodia Island is in the shape of a flare, and the seabed terrain is gentle, and the impact of tidal damage will naturally be more serious!

As Lin Feng spoke, the perspective of the drone shifted, photographing the situation on the west coast.

I saw that the water level along the coast was soaring, and the tide was up and down, surging and colorful.

In the distance, the sea level was shrouded in black fog, and it became more and more hazy, and the waves were raging and flooding.

Inside the camp.

Susan is working with the aborigines of the island, braving the wind and rain, sorting out supplies.

After about an hour, everyone was finally equipped.

Lin Feng checked inside and out again, carried two pieces of brass ore in his arms, and then picked up the bamboo basket and led them towards the hinterland of the island.

As he parted, he glanced back at the camp, his eyes becoming complicated.

The tiled house is crumbling, and it looks like it's going to die.

The water level of the collection tower is high, and the water is sprinkled.

The fence around the vegetable garden is crooked and dilapidated, and the young stalks of the new cassava are swaying in the wind.

In the end, the picture of the drone is frozen on the body of "Hawkins".

Its straw hat is long gone.

In the live broadcast room, the audience watched this terrible scene and sighed frequently.

"Hey, in front of nature, human beings always seem so small"

"Inexplicable tears"

"No matter how advanced human technology is, it will become helpless in the face of natural disasters. Thank you Feng Ye! I've never paid attention to this before! Respect for nature, start with me!"

"It's the first time I've seen a natural disaster with my own eyes, it's really terrifying!"

"Interesting souls are one in a million and give the anchor 1 shelter—— human beings are just children of nature, a very meaningful live broadcast, thought-provoking!"

"If the miracle has a color, give 10 bugs to the anchor—— the most positive live broadcast of Quandou Entertainment!

Viewed from the air, the island is shrouded in darkness and desolate.

In the woods.

The wind is getting stronger and stronger, destroying and decaying, and the direction is uncertain, so you have to bow your body and keep your center of gravity leaning forward in order to move forward.

A group of people.

Lin Feng was at the forefront, followed by Susan and the aborigines.

The camp is still some way from the exit of the tunnel, and you need to follow the stone road all the way to the north.

After walking for a while in the wind, the fountain tree was close at hand.

Because the rhizome and trunk of the fountain tree are very different from other trees, the soil fixing effect is very poor.

At this time, due to the sudden rainfall, the groundwater rises sharply, and the internal pressure on the surface increases sharply.

The land balance has long been disrupted.

As a result, the pressurized water bodies that had been accumulated in the cracks of the soil and rock formations for a long time rushed out of the surface cover and gushed out of the mountain in an instant!

Below the tree.

The ravine, which was originally a natural formation, has long since been washed away, forming a large-scale torrential rain and flash flood.

A chasm with a great span blocked everyone's way.

The water in the ditch is turbulent, mixed with sediment, and flows down the mountain.

Lin Feng looked around, frowned at the heavy rain, and shouted at the camera: "There is a big drop here! The slope of the canal is steep, the soil layer is very thick, and it is wrapped in a broken rock layer, so it is very prone to heavy rain and flash floods!"

"The tunnel, right in front of the woods. But now, we're blocked in our way by the rapids!"

"Something has to be done!"

The river valley is about three or four meters deep and five or six meters wide.

There is thick soil under your feet, and rock formations on the opposite bank.

At this moment, the turbulent river is eating away at the soil under their feet little by little.

The riverbed is still expanding.

It's impossible to jump over.

Lin Feng instructed everyone a few words and decided to go upstream to find a way.

But after looking around, the situation is not optimistic.

The soil layer upstream has been damaged even more, and there is not even a place to stay.

Landslides and small rock formations can be found everywhere.

If the torrential rains continue, it may soon be flooded.

They had no ropes, let alone folding ladders, and it was not easy to cross the rapids.

"Lin, what should I do?" asked Susan.

Lin Feng was silent for a while, and then spoke: "You can only build a bridge." ”

Susan was stunned, not understanding what he meant.

Lin Feng looked at the water potential upstream, then looked at the soil layer under his feet, and urged: "We have to build a single-plank bridge on this, and we have to move quickly." ”

As he spoke, without waiting for Susan to ask, he looked around the shore and chose a tree with a thick trunk that resembled a toon tree.

The tree is about four or five meters tall and has many branches.

The height and thickness are just right, and it is perfect for building bridges to cross the river.

Crucially, the tree has tilted because of the destruction of the soil, leaving its roots exposed and on the verge of falling to the ground.

The situation was critical, and Lin Feng didn't have time to explain, so he hurriedly took out a stone axe, knelt on one knee, and slashed at the root of the tree several times, and then hurriedly beckoned everyone, preparing to push down the big tree and lay it across the river valley.

The next moment, everyone braved the wind and rain, and after several exertions, they finally pushed the tree down, impartially, just above the rapids.

The roots of the Tsubaki tree are still firmly rooted in the soil, and it should last for a while.

The natives passed first, and Lin Feng and Susan broke off.

Because the bridge deck is sloping upwards, it is extremely difficult to walk.

Secondly, due to the influence of wind and flash floods, it is very difficult to control the balance of the body on it.

Even the native-born natives are inevitably a little overwhelmed.

Ten minutes later, the group stumbled and struggled to reach the other side.

Seeing this, Lin Feng hurriedly beckoned Susan to the bridge and instructed, "Quick, it won't last long here." ”

Susan exhaled, nodded, and stepped onto the tree, taking her first steps.

She is worthy of being a seafarer, she has seen strong winds and waves, and unlike ordinary women, she is very steady, even stronger than those natives.

At this time, the water became more and more fierce, and the bridge deck began to shake slightly.

Below, the earthy yellow rapids, surging and surging, continue to expand, about to engulf the bridgehead.

Considering the limited load-bearing capacity, Lin Feng waited until Susan crossed a third of the wooden bridge before jumping up.

The two of them walked forward slowly, one after the other.

As time passed, the canoe shook more violently.

In order to avoid stumbling, the two of them walked extremely carefully, controlling their center of gravity at all times.

I am not very sure, and I dare not raise my feet easily.

At this time, the wind is much stronger than before, and if you miss the pool, you will fall into the rapids.

There is silt and gravel in the water, you name it.

If this falls, it will never be recovered.

Don't make a mistake, even one step!

However, at this moment, a gust of wind suddenly hit, and the bridge deck suddenly moved, and it was forcibly moved half an inch to the left!
