Yesterday, with the rumbling thunder and heavy rain, I stayed at home and watched a shocking and exciting disaster blockbuster "Doomsday Collapse", which was really appropriate. The film focuses on the story of a major earthquake that stretches from Los Angeles to San Francisco, and Dwayne Johnson plays a pilot in the Fire Department's Air Force Squadron, piloting an airplane to find and rescue his daughter. In addition to the shocking earthquake special effects in the play, there are also warm husband and wife and father-daughter feelings, which is worth taking a look at.
After watching this movie, the feeling about the earthquake is still difficult to calm, just today in the watermelon video creators three fathers laboratory video "the strongest earthquake in history, equivalent to 27,000 atomic bombs, caused by the tsunami across the entire Pacific Ocean" learned that the history of the earth has really occurred similar to the strong earthquake in the movie, the shock effect is not worse than the special effects of the movie.
First, the causes of earthquake formation
As we all know, the earth is composed of six major plates, and the squeeze and collision between the plates and the plates cause staggering and rupture at the edges of the plates and the interior of the plates, which is the main cause of earthquakes, and volcanic eruptions can also cause earthquakes.
Earthquakes can be divided into the following four categories according to the different causes of occurrence:
1 . Tectonic earthquakes
Tectonic earthquakes are the situation of most earthquakes, which is the large-scale earthquake caused by the movement of plates mentioned above.
2 . volcanic earthquake
As the name suggests, the enormous amount of energy emitted by a volcano erupts causes a tremor on the Earth's surface.
3 . Collapse earthquake
Earthquakes caused by stratigraphic collapse. Such earthquakes occur less frequently and are generally of a small magnitude
4 . Man-made earthquakes
For example, the underground nuclear bomb experiment and other artificial local shaking of the ground.
Second, the harm of earthquakes
Whether in film and television dramas or in real news, we all know that earthquakes are a destructive natural disaster, and while we are afraid of it and afraid of it, we must slowly learn to understand it and gradually overcome it.
The main harm caused by earthquakes to us is as follows:
1 . Loss of human life and safety and property
The Wenchuan earthquake of May 12, 2008 is still fresh in our minds, which caused 69,227 deaths, 374643 injuries, and 17,923 missing, making it the most destructive earthquake since the founding of New China. In addition to the direct economic losses caused by the earthquake to the safety of human life and property, the mental damage caused by the earthquake is also immeasurable.
2 . Destruction of the ground
Such as ground cracks, collapse, spray water and sand and so on. Destruction of natural objects such as mountains, such as landslides, destruction of natural objects such as mountains.
3. Secondary disasters such as tsunamis and fires
In the movie "Doomsday Collapse", this tsunami caused by the earthquake was also staged, and the movement of the earth's plate will not only occur on the ground, but also affect the seabed. Damage to power systems after an earthquake can cause widespread fires, and sometimes the casualties and losses caused by these secondary disasters are greater than the direct disasters of the earthquake.
Third, how to save yourself in an earthquake
1 . avoid
We know from elementary school that triangles are the most stable structures, so when an earthquake occurs, we try to hide in the triangular area of the room or building, naturally curl up to avoid exposure. Wooden furniture can shake with the force of the earthquake, so it is also a better choice to avoid earthquakes, we can hide under the bed or under the table and other relatively safe spaces.
2 . Turn off the heat
When we talked about the hazards of earthquakes earlier, we learned that secondary disasters, fires, can also cause us great harm, so when an earthquake has just occurred or is temporarily stopped, we must try to close all facilities that may cause fires, such as open fires or gas. If a fire has already occurred, extinguish the fire immediately before the big shake comes or when a small shake is perceived to reduce the degree of loss caused by the secondary disaster.
3 . escape
After the earthquake, you must take the opportunity to quickly escape from the building, do not take the elevator during the escape, and should walk against the inside of the wall, away from glass windows, counters, chandeliers and other dangerous items. In public, do not rush to the exit in a panic, and stampedes should be avoided. When fleeing, you should not covet property, and carry goods to a minimum.
Most of us have not personally experienced a real earthquake, so you can go to the video of the watermelon video creator's three dad labs to feel the truth and horror of history, and you can understand how magical and powerful nature is. Earthquakes, floods, plagues, meteorites will come at any time, and human beings are constantly fighting against natural disasters and constantly learning how to protect our common earth home. There is more about the magic and mystery of nature in the watermelon video, welcome to the homepage of the three dad labs to learn more knowledge.
