Before the current human aerospace technology has not broken through the N technical barriers, no aerospace machinery dares to operate in the area covered with volcanic ash. Today's aircraft, both military and civilian, use internal combustion engine technology, which works by drawing in air, which in turn produces energy. Volcanic ash is capable of burrowing into the parts of aircraft engines, causing all sorts of damage.

Just like driving a car in a sandstorm, the internal parts of the engine will be clogged.

In addition, tiny particles in volcanic ash can clog the pitot tube, the airspeed sensor. Dust can clog these devices, which can produce false readings. As a result, the aircraft stalls and the pilot may not know the speed at that time.

And as the furious Mayon Volcano sprayed tens of thousands of tons of volcanic ash into the sky, the sky within a radius of several hundred kilometers centered on Mayon Volcano was already covered with volcanic ash, and even the sun was obscured. The air rescue channel was completely blocked by the volcanic ash, and the ground rescue channel could not be opened - who dared to sail the boat, was it really a joke that the first undersea earthquake was a joke?

So far, there are many strange whirlpools and undercurrents near the sea area where the submarine earthquake occurred, which is caused by the submarine earthquake after the submarine earthquake changes the topography of the seabed.

In the past few days, everyone has been idle in the villa and has nothing to do, and according to the information received by Li Huan through the radio, the undersea earthquake that occurred at about 10 o'clock yesterday morning was located in the Pacific Ocean, about 190 kilometers southeast of Legazpi, which happened to be in the Philippine Trench, the fifth deepest trench in the world, and the depth of the epicenter was only a pitiful six kilometers.

In other words, this earthquake should be the big brother of the Pacific plate who started to lose his temper again for some reason, and it may be that the big brother of the Pacific plate is not convinced by the Eurasian plate again, why are you larger than me? So, the Pacific plate slammed into the Eurasian plate for a while, and as a result, it caused this undersea earthquake of 8.9 on the Richter scale......

Although the epicenter is located on the bottom of the sea, it can not stand the magnitude is too large, so the consequences of this earthquake are still extremely terrifying, almost all the roads leading to the southeast of Luzon from the outside world have been destroyed, although the area of Samar Island in the south is not small, but it is also a poor island, in this earthquake is also seriously affected, in urgent need of rescue from the outside world. But whether it is the southeastern tip of Luzon Island or Samar Island, it is full of mountains, and it is said that "there are no three sunny days and no three feet of flat land", which is what we are talking about.

Once the roads in the mountains are destroyed, it is no less difficult to enter the disaster area in a short period of time than to open up air rescue channels.

No way, then take the sea route. After all, the Philippines is an island country, and there are not many other countries in this country, but there are many islands, mountains, and there seem to be a lot of people...... But is it better to go by sea?

The approaching super-strong hurricane "Zeus" expressed extreme unconvincing.

Zeus was not originally called Zeus, but more than ten hours ago, because its convective clouds were orange, and there was a cute name "orange", but a few hours ago, due to the rise of submarine tidal gas caused by the submarine earthquake, a large stream of hot air on the water surface was sucked into the low-pressure clouds, resulting in this hurricane, which was originally marked as a level 12 hurricane, and a hurricane with a cute "orange" name, instantly upgraded to an unprecedented level 17!

The cute name "Tangerine" was immediately given a new code name, which was "Zeus", which was codenamed after the father of the gods in Norse mythology! That's right, Zeus, who had just been upgraded to a super hurricane just a few hours before the earthquake and tsunami erupted, may have been watching his brother volcanoes, tsunamis, and earthquakes from a distance, so he couldn't bear the loneliness.

So in just one day, "Tangerine" upgraded from a hurricane to a strong hurricane, and then from a strong hurricane to a super hurricane "Zeus"!

I have to sigh at Zeus's upgrade speed, but this guy's upgrade is so cool, all the people who want to rescue the disaster area are completely dumbfounded.

What is the concept of a Category 17 super hurricane?

Very simple!

A Category 17 hurricane has winds of 56.1-61.2 m/s, or 202-220 km/h, which is faster than the average speed of an Formula 1 car. In other words, if you're lucky enough to sit in an F1 car, full throttle, and the wind blows from the top, you're feeling the wind at force 17. After a hurricane of this magnitude makes landfall, all the trees fall to the ground where it blows, even a hundred-year-old tree as thick as a few people hug it, and even the bark can be scraped clean for you. For parked vehicles, no matter what tonnage, they can be scraped over. It is also difficult for the telephone poles and street lamps along the way to stand, like some old bridges that have been built for a long time, basically will be scraped off. For houses, simple houses don't need to be explained, I don't know where to fly, brick houses can be swept away by a hurricane a roof, almost all collapsed, and concrete houses, although not collapsed, but doors and windows and the like can't be saved.

And the most terrifying thing is that once a super hurricane makes landfall, it often causes a storm surge. Although this storm surge cannot be compared to yesterday's tsunami, it is definitely a catastrophe for humanity. This storm surge is much larger than the normal high tide, and the waves can lift several stories high, and houses in coastal areas can be submerged in the sea in an instant. Therefore, once a super hurricane makes landfall, the damage caused is even greater than that of an earthquake, tsunami, or volcanic eruption. The fact that hurricanes were able to rank first among the five major natural disasters is not a joke, but a real evidence.

Earthquakes, volcanic eruptions or tsunamis, perhaps a single lethality is more than a hurricane, but it can't stand the hurricane many times a year, just like last year, Mangkhut and Maria landed in China, and the wind force at the time of landfall was 14, which can only be regarded as a strong hurricane; Connie and Feiyan landed in Japan and South Korea, and the wind force at the time of landfall was also a strong hurricane; and when Yutu landed on Luzon Island in the Philippines, the maximum wind near the center was also 14, which belonged to the strong hurricane level.

Last year, these strong hurricanes that made landfall alone caused huge losses to the coastal countries of the western Pacific, and if Zeus did not weaken, the damage would have been even greater if he had come at the level of a super hurricane. In fact, watching the hilarious Zeus who was playing there with a few brothers, he really couldn't hold it back. This guy happily upgraded and upgraded, and finally when he reached the sea about 200 kilometers southeast of Luzon, it successfully upgraded to become the strongest hurricane on record in the Philippines, with a maximum wind speed of more than 60 meters per second at the center!

Zeus approached the Philippines in a posture of dominating the world, and although the radius of the seventeen-level wind circle was only a few dozen kilometers, the thirteen-level wind circle that could not stand this guy was nearly 300 kilometers! That is to say, when Zeus upgraded to a super hurricane, the scope of his thirteen-level wind circle had already enveloped all the disaster areas. Waves set off by a force 13 wind can be as high as 10 meters or more, and under such circumstances, who would dare to go to sea? Even aircraft carriers and oil tankers of several hundred thousand tons would not dare to go to sea in such sea conditions, let alone rescue ships with a maximum tonnage of about 10,000 tons.

To go to sea in such a situation is purely to find death!

The Philippine authorities were also blocked by this high-spirited Zeus, a super hurricane, if in the past, it was comparable to the existence of a thermonuclear bomb, and if you come to it once, you have to peel off your skin if you don't die. Now it's good that this Zeus is coming back to join in the fun after the volcano, the earthquake and the tsunami, which doesn't let people live......

Of course, from the beginning of human walking upright to the present, it is actually a history of struggle against nature.

Floods, droughts, high temperatures, cold waves, floods, flash floods, forest and grassland fires...... These natural disasters that occur all the time may be just an instinctive reaction to a slight physical discomfort for Mother Earth, but for human beings, especially ancient humans, it almost means annihilation. Even in modern times, human beings are still irresistible to these natural disasters, especially as human beings become more and more serious in the destruction of Mother Earth, Mother Earth's temper has begun to become more and more irritable, and more and more natural disasters are punishing human beings.

Volcanic eruptions, tsunamis, earthquakes, hurricanes, and tornadoes are classified by modern humans into the five most devastating natural disasters

Undoubtedly, earthquakes are the most important, followed by tsunamis and tornadoes, and volcanic eruptions are more destructive to the atmosphere and have a lasting impact on the natural environment. Many scientists say that if the supervolcano in Yellowstone erupts, it will destroy the planet. In fact, this statement does not mean that the eruption of the Yellowstone volcano will directly destroy the earth, after all, no matter how big the Yellowstone volcano is, it is just a drop in the ocean for the entire earth. This theory mainly refers to the fact that once the Yellowstone volcano erupts, the erupted volcanic ash will cause secondary disasters similar to nuclear winter on the earth, when the volcanic ash in the atmosphere will block the sun's rays for years or even decades, which will cause the extinction of the earth's vegetation.

Without plants to provide oxygen and food, humans would not be able to survive.

Volcanic eruptions can't directly cause much harm to humans.

Although tornadoes are violent and destructive, the scope of impact of tornadoes is too small, so tornadoes rank the lowest among these five natural disasters. The power of the tsunami is undoubted, and the casualties caused by the Indian Ocean tsunami are as high as nearly 300,000, which is a very terrifying number. But again, a tsunami of this magnitude is not necessarily encountered once in a few years or even decades. As for earthquakes, high-level earthquakes are even more terrifying, causing horrific casualties and property losses, but in the same way, this kind of earthquake that kills tens of thousands of people at one time only happens once every few years or even more than ten years.

But hurricanes are different, there are dozens of them every year, whether it's the western Pacific or the western Atlantic, there are at least twenty or more hurricanes or hurricanes every year, and in these hurricanes or hurricanes, at least three or four strong hurricanes make landfall every year. Once such a strong hurricane makes landfall, the damage is often measured in "billion dollars", and the death toll is horrific if the residents are not evacuated in time. Like Hurricane Kaliona in 2005, the wind caused $200 billion in damage and nearly 2,000 people died or went missing.

Therefore, human beings have combined these natural disasters and finally identified hurricanes as the natural disasters that cause the greatest harm to human beings.

The main reason is that hurricanes happen too many times a year, and the residents of the west coast of the ocean are tormented by hurricanes every year, but with the current technology of human beings, there is no way to deal with this terrible natural disaster. Wrong, human beings can easily solve such extreme natural disasters by filling powerful weather satellites in outer space, as shown in the Citigroup blockbuster "Geomagnetic Storm".

But after all, it's a movie, and human beings can only YY in the movie now, and if there is a super hurricane coming, human beings are still helpless. This time, the Philippines doesn't know which god it provoked, the submarine earthquake, tsunami, volcanic eruption and the ensuing super hurricane Zeus all erupted together, any of these four natural disasters happened in a certain place, it is extremely rare, as for the four gathered together to erupt, it is simply unheard of. But the Philippines, an island country in the western Pacific, has caught up with such a big pot of things so tragically.

Therefore, the eyes of the whole world are attracted to this small island nation.

But no matter how attractive it is, the outside world cannot get the specific situation of the disaster area, and the ubiquitous volcanic ash refuses to sail. Empty. Even the high-resolution spy satellites in the sky could not see the situation in the disaster area under the thick clouds and volcanic ash, and the people outside only deduced the damage to the disaster area based on some fragmentary information.

In fact, the situation in the disaster area is really miserable!

The first undersea earthquake that destroyed most of the buildings in southeastern Luzon, Catandunes, Leyte, Dinagat, Siargao, and the eastern coastal areas of Mindanao was already terrifying. The Philippines is no better than its neighbor to the north, Japan, where this kind of undersea earthquake that occurs 1,200 kilometers away from the island can hardly cause any damage to buildings, but the Philippines can't. The Philippines is a poor country after all, and only a few limited cities in the country have sturdy buildings, and the vast majority of cities are so rudimentary that they can't withstand an earthquake of this magnitude!

The ensuing huge tsunami swept across the eastern coastal areas of the above-mentioned islands in an even more terrifying manner, including a series of coastal cities such as Legazpi and Tacloban, which were directly destroyed by the tsunami. Several smaller islands were simply washed by the tsunami, and the cities, buildings, and people on the islands were devastated.

Although the outside world is still unable to count the damage in the disaster area, everyone knows that this earthquake and tsunami alone are very likely to set a new record for the number of dead and missing persons in human history! And the huge amount of volcanic ash produced by the eruption of the Mayon Volcano, which is the most worrying, is the least harmful to the outside world, but Li Huan, who is in the core area of the disaster area, knows it very clearly.

It's ridiculous to say that the root cause of this change is none other than the super-powerful Hurricane Zeus that followed.

It only took half a day for "Zeus" to arrive in the Philippine waters from its birth, and when Zeus upgraded to a super hurricane, this guy's temper was much bigger, and he pounced on the Philippines with wind and rain. Although the eruption of Mayon was violent, sending thousands of tons of ash into the sky, the tiny Mayon volcano was too weak in front of Zeus, who had a cloud system with a diameter of more than 1,200 kilometers. Strong winds blow huge amounts of volcanic ash so much that it is impossible to rise into the stratosphere of the atmosphere, even if the seven-level wind circle around the hurricane is enough to blow the volcanic ash everywhere, but no matter how it flies, as long as the volcanic ash does not fly to the stratosphere, then the damage to the atmosphere of the volcanic ash will be reduced to a minimum.

And as the center of "Zeus" got closer and closer to the Philippines, the overwhelming rainstorm washed the volcanic ash all over the place. As we all know, volcanic ash does not dissolve in water, but the rain brought by Zeus is too great and too widespread, and the ash spewed out by Mayon Volcano has not yet begun to wreak havoc, and it is carried to the ground from the air by the torrential rain, forming a black acid rain.

"Li Huan, this kind of acid rain is really uncomfortable on my body, but this is the first time I have encountered acid rain. Yu Ting and Li Huan stood in the master bedroom on the second floor of the villa, looking at the pouring rain outside through a gap.

They've been here for two days.

Since Li Huan took everyone into the villa, collecting food and storing fresh water, Li Huan has become an absolute commander, but for the sake of watching Li Huan escape with everyone, everyone also listens to Li Huan's command very much. Whether it was Li Huan's letting everyone collect fresh water or implementing the food system of the distribution system, everyone had no complaints. Because Li Huan has made it very clear to everyone when he implemented these regulations, the government's disaster relief team will definitely not come soon, so if the food in the villa is not enough, everyone must save money.

In fact, fortunately, Li Huan is here, if Li Huan is not here, and only Yu Ting is here alone, then this team must have fallen apart, because Yu Ting will not be able to control such a terrifying post-disaster psychological problem management. Don't underestimate the problem of psychological construction after the disaster, in fact, the most terrible thing in the face of the disaster is not the disaster, but the psychological problems of people after the disaster. Huge natural disasters can cause subtle changes in people's psyche. These so-called changes can be positive or negative, and in more extreme cases, people will go to a dead end, do things that they would never have done before, and even go to murder and crime.

At this time, it is necessary to have a strong leader to reassure everyone, if this leader can make everyone feel at ease, feel that they have escaped the disaster and are absolutely safe, then everyone's psychological problems will be much more stable. And if the leader is not tough enough and does not give everyone a sense of security, then psychological problems are a real nightmare.

Li Huan's toughness and reliability were vividly displayed at this moment, and the team did not have any problems.

Now it's the volcano that's in trouble.

When a volcano erupts, it not only emits magma and ash, but also contains a large amount of sulfur and chlorine. The gas of gas, under the baptism of heavy rain, will immediately turn into acid rain, and the damage to the surface is also very great.

"Well, this hurricane came at a timely time, otherwise if a large amount of volcanic ash flew into the stratosphere, the damage to the atmosphere would be almost catastrophic. Thanks to this hurricane, the damage of volcanic eruptions was minimized. ”

Yu Ting nodded, she agreed with this statement, but it didn't mean that she liked to be stuffy in the house: "However, it's really uncomfortable to always hold back in the house." ”

Because of the arrival of the super hurricane Zeus, since yesterday evening, a group of people have braved the wind close to level thirteen and sealed all the windows of the villa with strong wooden boards. Li Huan had already learned through the radio that Zeus had been upgraded to a super hurricane, and the maximum wind force might exceed 17 when it made landfall in the Philippines.

Fortunately, I don't know if God blesses, Li Huan's island is not the route of the hurricane, although the hot air rising from the submarine earthquake has sharply increased the wind power of "Zeus" by several levels, but such an increase has also made "Zeus" change its route - the hurricane that originally came straight to Catandanes Island actually deviated from its route......

This is the most fortunate thing that Li Huan feels!

Because although this villa is sturdy, if it passes by the center by a seventeenth hurricane, it is really difficult to say what is left here - in that case, let alone protect people, even Li Huan may not be able to protect himself.

Fortunately, although "Zeus" has become more powerful, its route has deviated from the island of Catandunes, and only the outer wind circle is raging on the island of Catandunes. It was also under such circumstances that the main body of this villa withstood this super hurricane - but the doors and windows would definitely not be able to be saved, so Li Huan ordered everyone to take action and seal all the doors and windows of the villa. The four cars outside also drove into the garage of the villa, otherwise with the strength of Zeus, these four cars would not know where they would be scraped.

"Okay, wait patiently, by this time tomorrow, we will be able to go out, now that the hurricane is coming, if you get out of this room, a gust of wind will blow you away...... Scraped you away, where am I going to find you. Li Huan smiled faintly: "In this situation, it's good that we have a place to shelter from the wind, and after the hurricane passes tomorrow, I'll take you out for a walk and see if you can find any other food." Looking at this situation, no one will be here for a few more days, and we will have to look for some extra food...... I'm afraid that the wind circle will turn back, and it will be troublesome. ”

......

Li Huan once again felt that he was really a crow's mouth.

Zeus's 13th wind circle made landfall at around 5 a.m. at Gamai on the northeastern corner of Samar Island, about 120 kilometers south of the island of Catandunes. At this time, it is still not considered the actual landfall of "Zeus", because according to the definition of hurricane landing, only when the eye of the hurricane lands, it is considered a real landfall of the hurricane.

The thirteen-level wind circle of "Zeus" has a radius of about 100 kilometers, so it will take five hours to wait until the eye of "Zeus" actually makes landfall - at first there is good news, that is, the hurricane makes landfall late, and the eye of the storm is also staggered - but as the scale of "Zeus" grows larger, "Zeus" The wind circle of Category 13 did not weaken after landfall, but continued to move north-northwest at a speed of 20 kilometers per hour, that is, the outermost part of the eye of the wind will still sweep to Catan Duanes Island. The landing of a super hurricane is a very terrifying thing, even if the real hurricane core has not yet landed, only the thirteenth wind circle has begun to land, and the momentum caused is extremely terrifying.

The storm raged wildly around everything, and the dense raindrops knocked on the wooden planks outside the doors and windows, dense like the sound of horses' hooves as thousands of horses marched. The wind with its strange howl turned the area into a ghostly sound, a sound that could scare the faint of heart attack.

And the most terrifying thing is the super storm surge brought by strong winds.

Storm surge refers to the abnormal rise and fall of the sea surface caused by strong atmospheric disturbances, such as tropical cyclones (hurricanes, hurricanes) and extratropical cyclones (cold waves). The rise and fall of sea level recorded by coastal tide gauge stations or estuarine water level stations are usually a combination of astronomical tides, storm surges, (seismic) tsunamis, and other long-wave vibrations that cause sea level changes. Conventional tide gauges have filtered out sea surface fluctuations caused by short-cycle waves of several seconds. If the storm surge happens to overlap with the astronomical high tide (especially the high tide during the astronomical high tide), and the storm surge is often accompanied by strong winds and bad waves, and the flood of the river is carried up, the tide often rises sharply in the coastal area affected by it, and even the tide washes away the seawall and pond, swallowing up the docks, factories, towns and villages, so that materials cannot be transferred, and people and animals cannot escape, thus causing great disasters.

Some people call storm surge "storm tsunami" or "meteorological tsunami", and in China's historical documents, it is often called "sea overflow", "sea transgression", "tsunami" and "sea tide", etc., and the storm surge disaster is called "tidal disaster". The spatial range of storm surge generally ranges from tens of kilometers to thousands of kilometers, and the time scale or period is about 1-100 hours, between earthquakes and tsunamis and low-frequency astronomical tidal waves. However, sometimes the area affected by the storm surge moves with the movement of atmospheric disturbance factors, so that sometimes a single storm surge process can affect the coastal area of one to two thousand kilometers for several days.

The storm surge has a period of 1-102 hours and is between an earthquake tsunami and a low-frequency astronomical tsunami. The height of the storm surge is proportional to the difference in pressure between the central pressure of the hurricane or depression and the outer periphery, and the sea level rises by about one centimeter for every kilopascal decrease in the central pressure. Large storm surges, especially when the storm surge and astronomical tide are superimposed, can cause the coastal water level to rise sharply, and seawater will backflow, and the waves will be rough and bad, and the flood will occur.

Of course, not every storm can form a storm surge, and whether a storm surge can become a disaster depends to a large extent on whether its maximum storm surge level overlaps with the astronomical tide high tide, especially the high tide during the astronomical high tide period. Of course, it will also depend on the geographical location of the affected area, the shape of the coast, the topography of the shore and the seabed, and especially the social and economic conditions of the coastal area. If the maximum storm surge level coincides with the high tide of the astronomical high tide, it can lead to a megatidal disaster, such as Hurricane Storm Surge No. 8923 and 9216. From August 28 to September 1, 1992, under the combined influence of Severe Tropical Storm No. 16 and astronomical tide, a storm surge disaster with the most extensive impact and very serious losses occurred on the eastern coast of China since 1949. The tidal disaster has affected seven provinces and cities. The combined effects of storm surges, high waves, strong winds, and heavy rain have affected tens of thousands of kilometers of coastline.

Of course, if the storm surge level is very high, it can cause severe tidal damage, even if it does not encounter astronomical high tides or high tides. This is the case with Hurricane 8007 storm surge. At that time, it coincided with the astronomical tide flat, and due to the occurrence of an extra-high storm surge level of 5.94 meters, it still caused a severe storm surge disaster.

Although this storm surge is not as spectacular as the tsunami of the great storm, it is also very powerful, and this day coincides with the astronomical tide, so driven by the gravitational pull of the moon and strong winds, the coastal areas of several islands in the eastern Philippines have set off huge waves of more than 10 meters, and the height of the storm surge is more than 7 meters.

This kind of storm surge once again made the coastal area that had just experienced a tsunami baptized again, but it doesn't matter, as the so-called lice are too many not afraid to bite, yesterday's tsunami has destroyed everything that can be destroyed, and the remaining things that cannot be destroyed are not destroyed by this storm surge. But this storm surge is not a one-shot deal like a tsunami, which lasts for a full day.

At six o'clock in the evening, the storm was not only not lessening but getting bigger, indicating that the core of "Zeus" was very close to the Philippines - that is, the eye of the storm was about to sweep away from Catandunes.

At six o'clock in the evening, at dinner, Li Huan and Yu Ting were sitting at the dining table eating bread, and the manic storm suddenly stopped, without warning, as if there was an invisible hand in the sky that wiped "Zeus" from the earth, and even the rare sun in the past three or four days was revealed, and there was silence everywhere.

Yu Ting was stunned for a moment, and then shouted in surprise: "Li Huan, has the hurricane completely passed?"

Li Huan smiled bitterly and shook his head, "Don't be naïve, the hurricane has not passed at all, on the contrary, this is the real landing of the hurricane!"

"Huh, is the actual hurricane landing?"

"That's right, this situation is actually caused by the passage of the eye of the storm, that is, we are now in the eye of the storm of "Zeus". ”
