1. The bedrock is only 70 layers. Just dig up in place. Dig up for 3 times, lower your head for 3 times, and then go out
2. Nothing<
is the reason for the movement of Indian plate
mining energy is only a few hundred meters
the occurrence of earthquakes is several kilometers, dozens of kilometers underground
even hundreds of kilometers

3. It is related to the compression and collision between the Eurasian plate and the Pacific plate. Every year, the Pacific plate will squeeze 5cm to the Eurasian plate, and when the stress of the Eurasian plate is too large, it will rebound. This is the case with the Japanese earthquake
landlord, human intervention is not so simple
in recent years, the earth is changing rapidly
the ocean typhoons can't move the plate again because they are blowing hard
it's not a big problem!!!!

4. [generation and types of earthquakes]
earthquakes can be divided into natural earthquakes and artificial earthquakes. In addition, some special cases will also proce earthquakes, such as large meteorite impact on the ground (meteorite impact earthquake). There are many reasons for the vibration of the earth's surface. According to the causes of earthquakes, earthquakes can be divided into the following categories:
1. Tectonic earthquake
e to the rupture and dislocation of rocks deep underground, the energy accumulated for a long time is released rapidly and propagated in all directions in the form of seismic waves. The shaking ground motion caused by earthquakes to the ground is called tectonic earthquake. This kind of earthquake is the most frequent and destructive, accounting for more than 90% of the world's earthquakes< Volcanic earthquake
earthquakes caused by volcanism, such as magmatism and gas explosion, are called volcanic earthquakes. Only in volcanic active areas can volcanic earthquakes occur, which only account for about 7% of earthquakes in the world
3. Collapse earthquake
the earthquake caused by the collapse of underground cave or top of mine is called collapse earthquake. The scale of this kind of earthquake is relatively small, and the frequency is very few. Even if there are, it often occurs in limestone areas with dense karst caves or large-scale underground mining areas< Inced earthquake
the earthquake caused by reservoir water storage and oilfield water injection is called inced earthquake. This kind of earthquake only occurs in some specific reservoir area or oil field area
5. Artificial earthquake
the ground vibration caused by underground nuclear explosion and explosive blasting is called artificial earthquake. Artificial earthquake is caused by human activities. Such as instrial blasting, underground nuclear explosion caused by vibration; High pressure water injection in deep wells and Impoundment of large reservoirs increase the pressure of the earth's crust and sometimes ince earthquakes
the place where the seismic wave originates is called the source. The vertical projection of the source on the ground is called the epicenter. The depth from the epicenter to the source is called the source depth. Generally, shallow source earthquakes with focal depth of less than 70 km, medium source earthquakes with focal depth of 70-300 km and deep source earthquakes with focal depth of more than 300 km are called. Destructive earthquakes are usually shallow earthquakes. For example, the focal depth of the 1976 Tangshan earthquake was 12 km.

5. The building owner said that it is true that mining may cause earthquakes
combined with the case, the explanation is as follows:
in December 1989, an earthquake occurred in Newcastle, Australia, which was the most serious earthquake in the history of the country. The cause of the earthquake was mining< In December 1989, a 5.6 magnitude earthquake occurred in Newcastle, New South Wales, Australia, causing 13 deaths, 160 injuries and a loss of 3.5 billion US dollars, making it the most serious earthquake in the history of Australia. However, the fuse of the earthquake was caused by the force that changed the stratum structure e to the continuous mining for more than 200 years. The discovery came from Christie Klaus of the Earth Observatory at Columbia University
Klaus presented his findings at the American Geophysical Society last month. He believed that the local miners moved thousands of tons of coal, which put great pressure on the formation and eventually led to the earthquake
in addition, the more important reason is that in order to prevent the coal from being washed away, a large amount of groundwater is pumped away. For every ton of coal g, more than 4.3 times as much water is pumped away, Klaus said. In order to meet other needs in the process of mining and ore making, another 150 tons of water need to be pumped away for the collection of each ton of coal. The decrease of groundwater puts great pressure on the earth's crust< There are many cases of earthquake caused by human activities. Klaus pointed out that in the past 60 years, at least 200 earthquakes were caused by human activities, which was very rare before World War II. Most of these man-made earthquakes are caused by mining, and nearly a third are caused by reservoir construction. In addition, oil and gas proction can also cause earthquakes< Klaus pointed out that the three largest man-made earthquakes so far were all in gasri, Uzbekistan. Due to natural gas exploitation, three large earthquakes occurred continuously from 1976 to 1984, with magnitudes above 6.8 and the largest reaching 7.3
he also said that earthquakes caused by human behavior are more dangerous, especially in earthquake prone areas. Because people are rarely prepared for this, for example, the earthquake in Australia is not big, but because Australia is generally not an active place of crustal movement, the buildings in the city have no seismic capacity, resulting in greater losses
on the other hand, areas that are already seismically active are more likely to be triggered by earthquakes, because the pressure is formed over a long period of time, and once it breaks out, the consequences will be out of control
Claus's research has made many geologists start to think about whether there is a way to avoid man-made earthquakes. Klaus himself believes that the only way to avoid it is not to extract groundwater while mining. But the problem is that many profit oriented miners are not aware of this

6. In a small area, the stress release caused by the development of mineral resources may ince earthquakes, but the magnitude is often very small
but for the global large-scale frequent earthquake and volcano events, human behavior on the earth's surface has little impact on them

7. Mine earthquake refers to the earthquake inced by mining. A large area of cavity is formed ring underground mining. Affected by the local tectonic stress, mining and excavation additional stress and the change of earth stress field, a high stress concentration area is formed in the local area. Under certain inced conditions, it is released rapidly and violently, causing strong ground shaking and shaking. Mine earthquake is one of the main environmental problems in mines, and it is also an important cause of ground subsidence. The source of mine earthquake is shallow and the surface wave is rich, which belongs to inced earthquake. The period of mine earthquake is longer than that of natural earthquake, which is related to the propagation of seismic wave in shallow stratum. So far, the largest mine tremor in the world is 5.5.
8. Collapse earthquake: a kind of earthquake. The earthquake caused by rock collapse is called collapse earthquake. It mainly occurs in areas where limestone and other easily soluble rocks are distributed. This is because the easily soluble rock has been eroded by groundwater for a long time and many caves have been formed. The collapse of the cave top caused the earthquake. In addition, the collapse of large rocks on high mountain cliffs or hillsides can also form such earthquakes. In areas where limestone and other easily soluble rocks are distributed, collapse earthquakes often occur.

if you want to share the Internet, just set your router to DHCP mode.
