This can be said to be very safe.

It doesn't take much explanation to do these things, and it doesn't need much explanation.

If you change someone, it's too difficult.

"That'...... What about the provincial affairs? Yunhua asked in a low voice.

Bo Siqing took a sip of water before he said, "What I was going to tell you before is the matter of the province. Do you know? In fact, there are many earthquakes in the country every year, and the intensity of the earthquakes is very low, the magnitude is very small, and the vast majority of earthquakes are not even felt by people. ”

Yunhua nodded, "I know, the island nation is like that. ”

"The phenomena of earthquake clouds and animal anomalies mentioned earlier are all signs of an earthquake, but they are not accurate, because they may be too far apart to predict the exact location."

"Have you ever heard of the eye of the typhoon? ”

Yunhua thought for a moment, "I've heard of it, but I don't understand what exactly is going on." ”

"Actually, the reason is very simple, a typhoon is actually a storm group, and the really windy place is in the surrounding area...... Let's explain it this way, it's like a ceiling fan, the wind is all around, if it's directly under the fan, there is no wind in the center. This is not an appropriate example, because the situation of typhoons is not quite the same as this one. ”

"The typhoon rotates counterclockwise, and under the action of centrifugal force, the clouds in the center of the storm will deviate to the surrounding area, so that the central part creates a vacuum."

"In places covered by the eye of the typhoon, there will be a brief period of no wind, and even clear skies and sunshine! However, after the eye of the typhoon, there will be extremely bad weather! ”

Yunhua nodded, "I roughly understand, what does that have to do with the earthquake?" ”

"Earthquakes are related to continental plates, and they are also related to seismic migration zones."

"I'll tell you the result directly."

"The Provincial Earthquake Bureau used to be the department with the strongest earthquake prediction ability, and there are many retired veteran cadres who have been engaged in earthquake tracking and research all their lives."

"Last year, there were some small earthquakes there, and the veteran cadre marked the earthquake points...... Normally, these small crustal energy releases are carried along the earthquake, but somewhere, empty areas appear. ”

"Empty space?" Yun Hua was stunned for a moment, "It's similar to the eye of a typhoon?" ”

"Yes, the empty area, that is, there is movement around it, but there is no here." "Generally speaking, this means that there is a high probability that there will be an earthquake in the area that is higher than the surrounding area. For example, the ground movement anomalies in the surrounding area can only be detected by instruments, but if there is an earthquake in the empty area, it may be an anomaly of magnitude 2-3 that can be felt by humans. ”

Yunhua nodded, indicating that she understood.

"This kind of ground movement anomaly detection, including the situation of the seismic zone and the drawing of the map, requires a large number of professional staff."

"I do not deny that the bureaucratic style in some units is very serious now, and there are always people who do not do practical things. It's too big, and I've sent people from somewhere else. ”

Bo Siqing said, "You should know Mr. Li, a well-known geologist in our country and an academician of the Chinese Academy of Sciences? He proposed the existence of Quaternary glaciers in eastern China, established the concepts of "geomechanics" and "tectonic system", established the concept of "tectonic system", and founded the school of geomechanics. This paper proposes the understanding of the broad prospect of oil prospecting in the three subsidence zones of the New China tectonic system, and creates a way to predict earthquakes by combining active tectonic research and in-situ stress observation......"
