Homo sapiens

Suez Branch.

Gobi City.

At the same time that the immigration cruise ship arrived here, a Phoenix passenger plane also landed at the city's affiliated airport in the evening.

Weng Xuehai and several colleagues from the Geology Division got off the plane in a low-key manner, and then the group checked into a staff hotel exclusively for internal employees.

After a quick dinner in the hotel restaurant.

They were drinking tea in the private tea room of the hotel and talking about this mission.

"Brown, is your magnetic point analysis technology reliable?"

Curly-haired Brown Vincent replied confidently: "Don't worry, as long as the three-dimensional magnetic field detector is deployed, we can analyze the composition and structure of each formation."

Weng Xuehai looked at the holographic earth projected on his laptop and felt a little worried:

"According to your requirements, at least one magnetic field detector must be installed every 80 square kilometers on the earth's surface. In addition, magnetic field detectors must be installed on the seabed, high altitude, low-Earth orbit and synchronous orbit. This scale is very large."

Another bald researcher reminded: "It's not a big problem in our territory. The key is that other areas can only use magnetic field satellites in low-Earth orbit, and the data that can be collected is obviously not comprehensive enough."

"There's nothing we can do about it." Brown shrugged helplessly.

This time the mission of the Department of Geology is called [Earth Model].

The so-called earth model is actually a comprehensive scientific research project carried out to study the geological activities of the entire earth and to judge volcanoes and earthquakes.

Compared with traditional geological research, this time the Earth model of the Department of Geology of Homo sapiens will introduce various new technologies, including magnetic field detection, gravity detection, underground nuclear blast wave detection, and ultra-deep drilling.

This data is then used to build a comprehensive Earth model that can be used to predict earthquakes and volcanoes.

Among them, magnetic field detection is very important, because the Seismological Research Institute of the Department of Geology of Homo sapiens has collected a large amount of data in the Luzon Islands, Malay Islands, and Himalayan seismic zones.

Through these data, they discovered a very important phenomenon, namely: the changing patterns of plate stress and geomagnetism.

Whenever the plate releases stress, the surrounding geomagnetic field will undergo significant mutations.

The Homo sapiens company has very intensive magnetic field radars in Southeast Asia, and has also established a very comprehensive shallow surface magnetic field database. As long as there is a slight disturbance in the magnetic field, the magnetic field radar can detect anomalies.

It is based on this strict magnetic field monitoring that the Ministry of Geology successfully predicted 273 earthquakes and 3 volcanic eruptions in Southeast Asia. The accuracy of earthquake prediction was 86.4%, and the accuracy of volcanic eruption prediction was 100%.

This accuracy rate is already very high, and it is not detected within a few minutes before the outbreak, but can be detected several days in advance.

Because the geomagnetic mutation caused by plate stress does not suddenly change suddenly, there are some precursors, and then it reaches the peak at a certain moment.

In fact, this detection method is based on the magnetic field sensing ability of animals, especially birds, that researchers from the Homo sapiens company drew on.

Many people will find that before an earthquake breaks out, there will often be large-scale phenomena such as pigeons getting lost, livestock panicking, and mice moving.

This is actually because animals detect sudden changes in the surrounding geomagnetic field, especially birds that rely on geomagnetic navigation, and they fly around because of this.

In the past, humans had no way of detecting such subtle mutations in the geomagnetic field, and it was difficult to make accurate judgments based on animal behavior.

However, Homo sapiens who have developed magnetic field radar can detect abnormal changes in the geomagnetic field through this subtle magnetic field change and supercomputer analysis.

After accumulating a large amount of earthquake data, the Ministry of Geology finally established a complete earthquake prediction system.

Southeast Asia has basically been able to avoid sudden earthquakes, especially sudden major earthquakes.

Because the precursors of magnetic field mutations for sudden major earthquakes are too obvious, earthquakes with magnitude below 5 are easily affected by other factors, leading to misjudgment.

This earth model project is to promote the successful experience of Southeast Asia to the global scale.

But the magnetic field radar is one of the core secrets of Homo sapiens. It was the accuracy and concealment of the magnetic field radar that allowed Homo sapiens to defeat America.

Therefore, there is definitely no way for magnetic field radars to be deployed around the world. We can only rely on magnetic field radars in low-Earth orbit and high-altitude airships to build a rough earth model.

Of course, Homo sapiens' branches and subsidiaries in various places must be very accurate. In addition, areas close to Homo sapiens, such as central Africa, can also establish relatively complete earthquake and volcano monitoring systems.

On the contrary, the great powers that strictly guard against the Homo sapiens company can only monitor a rough idea.

The Geological Division has no intention of being warm-hearted about this. After all, the other party does not allow the Homo sapiens company's airship to enter the country. Could it be the so-called "big love" and take the initiative to announce the magnetic field radar technology or sell the equipment to the other party?

Obviously Homo sapiens company is not that stupid, and the management is not overly sympathetic.

Of course, the Earth Model Project is not just for detecting earthquakes and volcanoes, but has other purposes as well.

The magnetic point analysis technology that Brown is responsible for researching is to improve the accuracy of magnetic field analysis and achieve all-round analysis of the earth's crust, mantle and core through cross-monitoring of magnetic field radars in all directions.

What is the use of this technology?

This is also the reason why Weng Xuehai, a geologist and mineralogist, appears here. Through this technology, various underground resources can be accurately targeted, reducing the difficulty of field drilling and prospecting.

In addition, through accurate detection of the composition and structure of the formation, plate movement, fault structures, formation stress, magma chamber pressure, underground water network, etc. can also be analyzed.

This allows humans to study geological activities more intuitively.

Brown, Weng Xuehai and others came to the Suez Branch to study a special geological structure around the Suez Branch - the Nubian Aquifer.

The Nubian Aquifer is located in the northeastern part of the Sahara Desert, covering an area of ​​about 2 million square kilometers. It is located in the shale layer 500 meters underground and is rich in huge freshwater resources.

It is also the second largest known freshwater reservoir in the world after the Antarctic ice sheet, storing 160,000 to 350,000 cubic kilometers of freshwater, which is about 1.3 to 2.9 times the current total amount of human surface water.

However, there are some unknown risks associated with this kind of groundwater extraction.

Originally, the Geology Division did not pay attention to this problem.

It was not until some time ago that, in order to build a space city in the Suez branch, a comprehensive underground exploration was conducted in the local Harij oasis area, and more than 40 magnetic field radars were deployed around it, that some problems were discovered.

The Harij Oasis area had previously been pumping groundwater from the Nubian Aquifer.

Numidia next door has developed a large artificial river plan since the 1980s to extract large amounts of fresh water from the Nubian aquifer and transport it to the Mediterranean coast.

The water level in the Nubian aquifer is declining year by year after large amounts of groundwater have been pumped away.

Although there is no need to worry about land subsidence in desert areas, the large-scale reduction of groundwater will also cause another problem, that is, changes in stratigraphic stress, which will affect the stability of surrounding fault structures.

For example, in the Aztec region, the Geological Division of Homo sapiens Company analyzed magnetic field data and found that after pumping out large amounts of groundwater, the already unstable strata will become more unstable and easily induce earthquakes.

A lot of groundwater has been accumulated over tens of thousands or even millions of years.

Since modern times, human activities have been too intense for geological time.

The groundwater in an area may drop hundreds of meters in just a few decades. This change is like a person's artery being cut open, and the earth's crust cannot slow down all of a sudden.

Now the exploitation of the Nubian aquifer in North Africa has immediately attracted great attention from the Geology Division.

Although the extraction of groundwater has not been stopped, desalination technology has been used to replace part of it and the amount of local groundwater extraction has begun to be gradually reduced.
