Chapter 897

It can be said that this is very safe.

It doesn't need too much explanation to do these things on the basis of Bo Si Qing's identity.

It would be too difficult to change someone.

"Well What about the province? " Cloud painting asked in a low voice.

Bo Si Qing took a sip of water and then said, "what I want to tell you before is to save things. You know what? In fact, there are many earthquakes in China every year. The intensity of the earthquakes is very low, and the magnitude is very small. Most earthquakes are not even felt by people. "

Yun Hua nodded, "I know, that's what happened to the island."

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

Bo Siqing said, "have you ever heard of the eye of Taiwan?"

Yun Hua thought for a moment, "I've heard of it, but I don't understand what's going on."

"In fact, the reason is very simple. A typhoon is actually a storm group. The place with strong wind is around Well, it's like a ceiling fan. The wind is all around. If it's directly under the fan, there's no wind in the center. This example is not very appropriate, because the situation of typhoon is not quite the same as this one. "

"The typhoon rotates counter clockwise. Under the action of centrifugal force, the clouds in the center of the storm will deviate to the surrounding area, thus forming a vacuum zone in the central part."

"Typhoon eye shrouded places, there will be a short period of no wind phenomenon, and even clear sky and sunshine! But after the typhoon eye, there will be extremely bad weather! "

Cloud painting nodded, "roughly understand, what does that have to do with the earthquake?"

"Earthquakes are related to the continental plate and to the seismic migration zone."

"I'll tell you the result directly."

"The Seismological Bureau of Shen province was once the Department with the strongest ability of earthquake prediction. Many retired veteran cadres have been engaged in earthquake tracking and research all their lives."

"Last year, there were some small earthquakes. The old cadre marked out the earthquake points Generally speaking, these small crustal energy releases are carried away along the earthquake, but at some point, there is a gap

"Empty area?" Cloud painting Leng for a moment, "similar to the meaning of typhoon eye?"

"Yes, the empty area, that is, there are changes all around, but not here." "Generally speaking, this means that there is a high possibility of earthquakes of higher magnitude in this area," Bo said. For example, the surrounding ground motion anomalies can only be detected by instruments, but once there is an earthquake in the empty area, it may be an anomaly that human beings can feel with magnitude 2-3

Yunhua nodded to show that she understood.

"This kind of ground motion anomaly detection, including the situation of seismic zones and the drawing of maps, requires a large number of professional staff."

"I do not deny that the bureaucracy in some units is very serious, and there are always people who do not do practical things. It's too big. I've sent people from other places. "

Bo Siqing said, "should you know Mr. Li, a famous geologist and academician of the Chinese Academy of Sciences in our country? He put forward the existence of Quaternary glaciers in eastern China, established the new concepts of geomechanics and tectonic system, established the concept of "tectonic system", and established the school of geomechanics. He put forward the understanding of three subsidence zones of the new Cathaysian tectonic system, and created a way to predict earthquakes by combining active structure research with in-situ stress observation …”
