The weather in Lu Xian County, Sichuan Province

Because of the gravity of the earth, earthquakes often occur in the early morning or late at night. When the moon approaches the earth, there are strong tidal fluctuations in the ocean on the surface of the earth. The huge friction caused by this fluctuation makes the earth's temperature rise sharply, which leads to the melting of the center of the earth. Under the action of high temperature and high traction, the magma in the center of the earth rolls in a rotating way, resulting in a magnetic field. This "super giant" magnetic field has formed a "protective shield" for the earth, reducing the invasion of cosmic rays on the earth. Although the evolution of the weather system is complex, its essence is the strength, advance and retreat of cold and warm air masses, and the periodic atmospheric tides caused by the periodic change of lunar tidal force. Based on this, it is speculated that tidal force will vibrate during the periodic operation of the moon, so different tidal force also "command" the ever-changing weather and climate.

1. Because the earth is constantly moving and changing, it gradually accumulates huge energy, causing sudden fracture of rock strata or dislocation of original faults in some fragile areas of the crust. This is an earthquake. ? Most earthquakes occur in the earth's crust. According to scientific monitoring, tectonic earthquakes mostly occur in the range of 5 ~ 30 kilometers below the surface, which is a very destructive earthquake.

At the North Pole and South Pole of the earth, the magnetic field lines pass in and out from these two places, and the direction of electron movement is parallel to the direction of magnetic field lines. The movement of electrons is not affected by ampere force, so it has a faster escape speed, and will not form enough potential difference between layers because of accumulation, and will not occur earthquake phenomenon.

Third, the method of earthquake prevention can be inspired by the principle of "lightning rod". People can master earthquakes by monitoring electromagnetic anomalies between different strata in the earth's crust, and can also prevent destructive earthquakes by establishing a "damping mechanism" in the strata.

Four, the earthquake is divided into five categories:

1. Tectonic earthquake: The reason of tectonic earthquake is that underground strata are subjected to geostress. When the local stress is so great that the rock stratum can't bear it, it will suddenly break or dislocation quickly. When the rock stratum is broken or dislocated, it will stimulate seismic waves that spread around, and when local seismic waves reach the surface, it will cause ground vibration. 85%-90% of earthquakes in the world and all earthquakes that cause major disasters belong to tectonic earthquakes.

2. Volcanic earthquake: an earthquake caused by volcanic eruption.

3. Reservoir earthquake: an earthquake occurred in the reservoir area due to water storage and discharge.

4. Collapse earthquake: earthquake caused by stratum collapse.

5. Artificial earthquake: an earthquake caused by human activities such as nuclear explosion and artillery fire.
