Li Xun's words, speaking of this now, there are actually a few people who have vaguely guessed what kind of disaster Li Xun is talking about. Pen Fun Pavilion wWw. ｂiquge。 ｉｎfo

Xu Qianyun guessed and asked, "Li Xun, you can't say that it will cause a disaster like an earthquake, right?"

"Yes, it's an earthquake. Li Xun nodded.

Many people were stunned.

Earthquake?

Earthquakes are catastrophic.

Can this kind of underground creature cause an earthquake?

It's impossible, even if these underground creatures are huge, but they are just one underground creature, and what kind of earthquake can it cause?

But if you think about it, it seems possible.

After all, when they construct a network of underground caverns, they will cause more or less damage to the structure underground.

According to normal thinking, if the underground structure is destroyed, it may really cause an earthquake.

But there are also obvious objections.

Yang Zhenghui is obviously the one who has doubts, because he happens to know very well about earthquakes.

He hesitated for a moment and said, "But, Mr. Li, as far as I know, an earthquake is a vibration caused by the rapid release of energy from the earth's crust, which is mainly caused by the squeezing and collision between the major plates of the earth. ”

Seeing that among the hunters in Miao Village, a few did not understand much, Yang Zhenghui explained, "The crust of our entire earth is divided into six large plates, which seem to float on the surface of the earth, and at the junction of the major plates of the earth's crust, there are often extrusion collisions, which are prone to geological disasters such as earthquakes."

Of course, for example, volcanic eruptions can also cause earthquakes, and some earthquakes will occur at a depth of six or seven hundred kilometers underground, which is no longer the earth's crust and belongs to the asthenosphere, but in any case, earthquakes are natural disasters caused by geological tectonic changes, which is a scientific explanation that is more recognized by the scientific community at present. ”

Yang Zhenghui made such an analogy, and the hunters all nodded in understanding.

It just sounds weird, on the surface of the earth, what six major plates are floating on the surface?

Li Xun looked at Yang Zhenghui with a slight smile.

Yang Zhenghui immediately realized that perhaps there was something wrong with his words.

Scientific explanations?

Science may be able to explain some normal phenomena, but legendary hunters like Li Xun, many of the things they come into contact with cannot be explained by science, so Yang Zhenghui also laughed awkwardly, "Mr. Li, I said it wrong, right?"

Li Xun shook his head slowly: "Lao Yang's explanation of the earthquake is very correct, at present, most of the causes of the earthquake are indeed as Lao Yang said, but among them, there is a very special earthquake, which also has a scientific term, called the collapse earthquake." ”

Li Xunneng admitted Yang Zhenghui's explanation, which surprised Yang Zhenghui.

Just now he thought that he had explained it wrong, but he didn't think that Li Xun recognized his explanation.

Therefore, after hearing the term "falling earthquake", he was surprised, and hurriedly echoed: "Yes, yes, as far as I know, there is this very special earthquake, which is formed by the collapse and collapse of rock formations.

This kind of earthquake mainly occurs in karst terrain like where we are now, there are a large number of underground karst caves and underground faults underground, so when the roof of the cave collapses, it will cause a collapse earthquake, of course, on some high mountain cliffs and slopes, it will also cause serious collapse earthquakes because of the fall of some large stones. ”

Wang Ruyi suddenly realized when he heard this, he slapped his palms and said: "Oh, it turns out that these underground creatures are caused by this kind of falling earthquake, but it's right to think about it, so many holes have been dug out of the ground, once it collapses, it will definitely cause a large-scale collapse, just like a falling earthquake." ”

Li Xun smiled slightly: "Strictly speaking, the earthquakes caused by these underground creatures should be similar to the falling earthquakes, but often the caves constructed by these underground creatures are very secretive, and it is difficult to monitor them on a large scale by ordinary means, and it is even more difficult to find them, so the earthquakes caused by the collapse of these underground caves will be mostly classified into other earthquakes." ”

Yang Zhenghui was still a little puzzled, he looked at Li Xun, and said: "But, Mr. Li, as far as I know, the incidence of falling earthquakes is extremely small in the overall incidence rate of earthquakes, and the earthquake level it induces is usually very low, and the degree of disaster is not very large...... It doesn't match, does it?"

Li Xungang wanted to continue to explain, but Xue Qizhen answered.

"That's because you don't know much about the horror of this kind of earthquake, let alone you, even most seismologists, I'm afraid they don't know that there is also this huge earthquake caused by underground creatures. ”

Yang Zhenghui humbly asked, "Old Xue, can you explain in detail?"

Xue Qizhen said: "In fact, more strictly speaking, earthquakes caused by underground creatures alone are usually rare, after all, when underground creatures build their underground cave network, they will also consider the safety structure of underground caves in advance, they themselves are experts in this area, and they will not let their caves collapse in danger."

Therefore, in the natural case, although the scope of these cave networks is large, the density will be guaranteed to be within a reasonable range and will not cause collapse, but in the unnatural case, it is difficult to say. ”

Yang Zhenghui's eyes lit up, and he added: "Old Xue, do you mean that the collapse caused by these underground creatures may be caused by other earthquakes?"

Xue Qizhen stroked his little goatee with his hand, nodded and said, "Yes, because the underground creatures will dig the cave as wide as possible for their survival needs, or as Lingxi just said, to escape from us hunters, they will dig the cave as wide as possible, and it may extend for tens of miles, or even a wider area."

Of course, these underground creatures themselves can't judge the possibility of an earthquake, let alone take precautions in advance, but in this way, if a normal earthquake happens to happen in this area, imagine what will happen?"

Everyone was prompted by Xue Qizhen and conceived in their own minds.

At this thought, everyone changed color.

Assuming that other normal earthquakes have indeed occurred, and countless caves have been excavated by these underground creatures under the scope of the earthquake, the shaking will naturally increase the magnitude of the small-scale earthquake that may have been caused by the earthquake.

The reason is just like in a normal earthquake, a strong house can withstand an earthquake, and an old, broken house can't withstand an earthquake.

Once the underground cavern is elevated, the disaster caused by the earthquake will be even greater.

The old house was destroyed by the earthquake, and it was just an old house.

The ground has been hollowed out, and if it really is going to earthquake, I am afraid that it will be an entire area above the ground.

So it would have been devastating.

Its destructiveness is definitely not as simple as "1+1=2", normal natural earthquakes and cave collapse earthquakes, but is infinitely expanded.

Wang Ruyi's color changed, and he muttered: "Master, Old Man Xue, hearing you say this, is it possible, there have really been similar disasters in history?"

Li Xun and Xue Qizhen glanced at each other and nodded heavily.

"Yes, there are, and there are more than one or two of them, and one of them is probably not only one of the worst earthquake disasters in the history of China, but also rare in the world. Li Xundao.

Wang Ruyi asked: "Then which earthquake is it?" (To be continued.) )
