2. No more than 10 episodes. (The largest earthquake was Chile, with a magnitude of 9.5)
3. Earthquakes can indirectly cause fires, floods, toxic gas leakage and epidemic spread. Call it an earthquake secondary disaster.
Animals are running around barking, such as dogs, cats, elephants, and hibernating snakes are out of their holes. ② Well water is abnormal and the ripples are uncertain. (3) the phenomenon of terrestrial light. (4) generating earthquake clouds.
5.① At school: the teacher organized everyone to evacuate quickly, and the teachers and students evacuated to spacious places in an orderly manner, such as the playground.
② At home: If you have time to run downstairs, go down immediately. If you can't get down soon, just hide in a small room (corner) and cover your head with something.
③ In the commercial plaza: Don't crowd with others, tell everyone not to panic and queue up for quick evacuation. (You can also break the glass to escape)
In the cinema: In order to avoid being crowded by others (because the cinema is dark), the cinema generally has multiple exits, so choose the exit closest to you to escape.
6.① Self-help: Don't panic, be sure to avoid fainting, save your strength (if you have food around you, distribute it reasonably) and wait for rescue.
② Rescue method: If you can remove the ruins (such as bricks and digging), do it as much as possible. If not, actively encourage trapped students outside the ruins and inform the rescue team.
7. If it is carried out again, it will waste a lot of manpower and material resources. On the basis of the original building, more measures to prevent accidents (such as strengthening houses and improving the seismic quality of houses) should be established.
8. Infectious diseases: There are four categories: the first category is intestinal infectious diseases, which are mainly transmitted through feces. These diseases are all caused by the intake of polluted water and food, such as dysentery, hand, foot and mouth disease, hepatitis A and so on. People in disaster areas should pay attention to prevention.
The second category is respiratory infectious diseases. After the earthquake, people are highly concentrated, with great mobility and frequent contact with each other, which may easily lead to respiratory infections such as measles, rubella and colds. Especially now measles and rubella are in a high incidence period, so we must pay attention to prevention.
The third category is acute hemorrhagic conjunctivitis, commonly known as "pink eye". After the earthquake, people contacted frequently, and at the same time, the original life rules were disrupted. Especially in some disaster areas, in order to save drinking water, several people often use a basin of face washing water or a towel, which is easy to cause the outbreak of pinkeye.
The fourth category is Japanese encephalitis that may be prevalent. From June to August every year, the epidemic situation of Japanese encephalitis is high in some areas, and the disease is mainly spread by mosquito bites. This disease affects people's central system, has a high mortality rate, and easily leads to sequelae such as dementia, which needs great attention.
Prevention: ① Paying attention to drinking water and food hygiene is the key to prevent intestinal infectious diseases. Water sources (especially drinking water) should be protected from pollution.
② To prevent insect-borne infectious diseases such as Japanese encephalitis, malaria and kala-azar, comprehensive measures such as mosquito killing, mosquito prevention and vaccination should be taken. Control and manage the source of infection and isolate patients.
(3) People who cause skin injury for various reasons must be injected with tetanus antitoxin in time, and the wound should be debrided and sutured, and effective anti-inflammatory and symptomatic treatment should be given.
④ Do a good job in drinking water safety, select qualified water sources and protect them.
