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 Department 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 at the hotel restaurant.
They were drinking tea in the private tea room of the hotel while 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, there must be magnetic field detectors 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 within 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."
On the contrary, the great powers that strictly guard against Homo sapiens can only monitor a rough idea.
What is the use of this technology?
In fact, this detection method is a method that Homo sapiens researchers borrowed from the magnetic field sensing abilities of animals, especially birds.
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 earthquake prediction accuracy was 86.4%, and the volcanic eruption prediction accuracy was 100%.
Of course, the areas controlled by Homo sapiens must be very precise. In addition, relatively complete earthquake and volcano monitoring systems can also be established in areas close to the areas controlled by Homo sapiens and in central Africa.
Because the precursors of magnetic field mutations for sudden major earthquakes are too obvious, those earthquakes with magnitude below 5 are easily affected by other factors, leading to misjudgment.
However, there are some unknown risks associated with this kind of groundwater extraction.
In the past, humans were unable to detect such subtle changes in the geomagnetic field, and it was difficult to make accurate judgments based on animal behavior.
This is actually because animals detect sudden changes in the surrounding geomagnetic field, especially birds that rely on geomagnetic navigation, and will fly around because of this.
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.
Southeast Asia itself can basically avoid sudden earthquakes, especially sudden major earthquakes.
After accumulating a large amount of earthquake data, the Ministry of Geology finally established a complete earthquake prediction system.
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.
Through these data, they discovered a very important phenomenon, namely: the changing patterns of plate stress and geomagnetism.
Next door, Libya 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 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.
It was not until some time ago that, in order to build the Egyptian Space City, a comprehensive underground exploration was conducted in the Harij Oasis area, and more than 40 magnetic field radars were deployed around it, that some problems were discovered.
Since modern times, human activities have been too intense for geological time.
The Harij Oasis area had previously been pumping groundwater from the Nubian Aquifer.
Originally, the Ministry of Geology did not pay attention to this problem.
Whenever the plate releases stress, the surrounding geomagnetic field will undergo significant mutations.
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.
Obviously Homo sapiens company is not that stupid, and the management is not overly sympathetic.
After a large amount of groundwater has been pumped away, the water level of the Nubian aquifer is declining year by year.
The so-called earth model is actually a comprehensive scientific research project conducted to study the geological activities of the entire earth and to determine volcanoes and earthquakes.
Of course, the Earth Model Project is not just for detecting earthquakes and volcanoes, but has other purposes as well.
This time the mission of the Department of Geology is called [Earth Model].
A lot of groundwater has been accumulated over tens of thousands or even millions of years.
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 earth model project is to promote the successful experience of Southeast Asia to the global scale.
In addition, through accurate detection of the composition and structure of the formation, plate movement, fault structures, formation stress, magma chamber pressure, groundwater network, etc. can also be analyzed.
But magnetic field radar is one of the core secrets of Homo sapiens. It was relying on the accuracy and concealment of magnetic field radar that allowed Homo sapiens to defeat America.
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.
"There's nothing we can do about it." Brown shrugged helplessly.
The Ministry of Geology has no intention of being hot-tempered about this. After all, the other party does not allow Homo sapiens airships to enter the country. Could it be that it has become the so-called "big love" and proactively announced the magnetic field radar technology, or sold the equipment to the other party?
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.
This allows humans to study geological activities more intuitively.
Homo sapiens has very intensive magnetic field radars in Southeast Asia and has 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.
This data is then used to build a comprehensive earth model for predicting earthquakes and volcanoes.
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.
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.
Brown, Weng Xuehai and others came to Egypt to study a special geological structure around Egypt - the Nubian Aquifer.
For example, in Mexico, the Department of Geology of Homo sapiens analyzed magnetic field data and found that after large amounts of groundwater were extracted, the already unstable strata would become more unstable and easily induce earthquakes.
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.
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.
Therefore, there is definitely no way for magnetic field radars to be deployed all over the world. We can only rely on magnetic field radars in low-Earth orbit and high-altitude airships to build a rough earth model.
The groundwater in an area may drop hundreds of meters in just a few decades. This change is like a person having his artery 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 Ministry of Geology.
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.
