Hong Long Provincial Earthquake Department, Monitoring and Forecasting Center.

"Lao Chen, what are you doing in such a hurry to call me over in the middle of the night?"

Song Weimin was wearing a white shirt, a pair of big pants on his lower body, a pair of slippers on his feet, and his hair was messy, obviously in a hurry when he went out.

"Old Song, there is an earthquake over there in Yangqiu!"

Chen Tianlang held a thermos cup in his hand, sat on the chair of the monitoring table, he glanced at Song Weimin lightly, and then cast his eyes on the computer screen in front of him.

"When was the earthquake? Where was it?"

Song Weimin hurriedly leaned in front of the screen of the monitoring station and asked nervously.

"The time is 16:39 this afternoon, and the epicenter is in the mountains to the east, this is it-" Chen Tianlang pointed to the map on the screen with his hand and said, "M5.1, moderate to strong earthquake." ”

"Hey, it's only level 5.1, it's still in the mountains, it's good to send two interns to investigate, and you called me here in the middle of the night just for this?"

Song Weimin was unhappy, how could he say that he was also a deputy director, and he asked me to come over in the middle of the night for such a trivial matter? You are making too much of a fuss!

"Look at this again!" Chen Tianlang clicked the mouse, and a data window popped up on the screen.

"Seismic waves?" Song Weimin looked at the familiar line chart and glanced at Chen Tianlang with some confusion, but after he carefully looked at the line chart on the screen twice, he was suddenly shocked!

"Is this an artificial vibrator?"

"Yes!"

"Did you report it?"

"I just called. ”

"What does it say?"

"It says an investigation will be launched immediately......"

When Song Weimin heard this, he was shocked, and he was no longer the one who didn't wake up just now.

The 5.1 magnitude earthquake is not big, at most it is to shake the soil on the wall, and the epicenter is still in the mountainous area, and the impact is even smaller.

If it's a naturally occurring earthquake, then the process is perfectly fine, but if this earthquake is man-made, the nature is completely different!

The biggest difference between man-made earthquakes and natural earthquakes is the difference in seismic waves.

For a magnitude 5.1 earthquake, at least more than 1,000 tons of TNT are required to be blasted intensively to achieve this effect!

If this situation arises, if it is made by people from your own country, it should not be a big problem, if it is not made by your own country...... That's a big problem!

In this way, the two directors of the earthquake bureau sat in the monitoring center all night with wide eyes, and when it was dawn the next day, the eyeballs of both of them began to bloodshot, and the phone of the monitoring center finally rang.

Surprisingly, the other end of the phone was not the National Earthquake Administration, but the Fourth Military Region!

The eastern part of Yangqiu City is a barren mountain, and since the state implemented the rationalization and regulation of human resources 20 years ago, people in the mountainous areas have moved into the new area, so the mountains are basically uninhabited.

Early this morning, the citizens of Yangqiu City suddenly received a notice that an army was conducting exercises in the eastern mountainous area, and citizens were forbidden to enter the mountains for some time recently.

In the information society, this situation is already very common, so the military exercises in the eastern mountainous areas have not had any impact on the citizens, and those who should buy vegetables and go to work should go to work, and there is nothing in the mountains, so who will be idle and have nothing to do in the mountains?

At this time, the epicenter area has been firmly blocked by 20,000 soldiers from the Fourth Military Region, these soldiers are all loaded with live ammunition, and unlike the rumors outside, each of them knows that this is not a drill!

Song Weimin and Chen Tianlang flew directly by helicopter, after all, the mountain road is rugged and difficult to navigate, and if they walk on their feet, they will not be able to reach the epicenter area for a day or two.

Also sent by helicopter, there are three iron boxes the size of trucks, these iron boxes are filled with very sophisticated geological survey instruments, and the instruments in each iron box are worth millions, it can be said that this time the entire earthquake bureau has been brought over!

After the iron box landed, soon there were professional personnel to come to unpack, and then a group of old professors from the Geological Bureau commanded their graduate students to start the installation and debugging of these instruments, and it was not until noon that those important exploration equipment were basically installed.

Taking advantage of the instrument debugging, Chen Tianlang and Song Weimin came to a hill in the center of the epicenter, stood on the top of the mountain, and the two took the telescope to look at it for a long time, and after discussion, they finally selected the location for exploration.

The three groups of instruments were selected at three locations, and as soon as the military diesel generator roared, the three groups of instruments entered the working state in an instant.

The people of the Fourth Military Region set up a workbench on the hillside not far from the instrument, on which three laptops were displaying the data explored by the three sets of instruments, and the directors of the two earthquake bureaus and a group of professors from the geological bureau were staring intently at the screens of the notebooks, for fear of missing a detail.

"There's something here! Look!" It didn't take long for several old professors to spot the anomaly on the screen of a laptop.

"What time is this?" a group of people came over to take a look and quickly asked.

"It's the No. 1 machine!" The graduate student next to him quickly replied.

"Quick! Move both the No. 2 and No. 3 planes over! Use the triangulation method with a margin of 50 meters!"

Chen Tianlang spoke, and several graduate students immediately ran over with the engineers and began to carry the instruments.

"30 degrees to the east, a margin of one hundred and fifty meters!" After half an hour, Chen Tianlang shouted again.

"15 degrees east, three hundred meters apart!"

"Five hundred meters away!"

......

Chen Tianlang and a group of professors shouted very vigorously, but they suffered a group of graduate students and engineers.

After an afternoon of hard work, a group of people tossed until more than six o'clock in the evening, and finally determined the scope of the underground anomalous reaction.

The scope is determined, so what are you waiting for?

So, with a wave of his hand, the person in charge of the military region began to operate one by one the drilling equipment that had been prepared long ago, and the drill bit was drilled down against the ground!

Two days later, the drill bit reached a depth of about 400 meters, and suddenly there was a loud noise, and the drilling rig stopped working instantly, and when the engineer raised the drill bit, he found that the entire drill bit had been ground flat!

The accident caught everyone's attention, and before they could investigate the cause, several other rigs had the same accident.

An accident on a drilling rig can be said to be an accident, but all drilling rigs have a similar accident, so everyone has a bottom in their hearts, obviously, they have found something!
