Knowledge about preventing aftershocks;
1, strong aftershocks are the focus of prevention?
Because the earth is constantly moving and changing, it has gradually accumulated enormous energy. In some fragile areas of the earth's crust, an earthquake occurs when the rock suddenly breaks or the original fault moves. The complete release of energy requires a process. Aftershocks usually occur after the main shock, but they are also strong and weak. Smaller aftershocks can only cause slight ground vibration and are not easy to cause disasters, while stronger aftershocks are likely to cause further damage or collapse of damaged buildings and cause new casualties. Therefore, the prediction and prevention of strong aftershocks is the key.
2. The key to prevent strong aftershocks in mountainous areas.
Different types of areas have different emphases in preventing strong aftershocks. 5. 12 Wenchuan earthquake occurred in mountainous areas, and the key points of prevention mainly include the following:
The first is to prevent the occurrence of secondary disasters. There are many hidden dangers in this area, such as landslides, collapses, rolling stones, dammed lakes and reservoirs. In addition, there has been continuous rainfall in the disaster area recently. Once a strong aftershock occurs, these hidden dangers are likely to cause traffic jams, floods and new casualties, so preventive measures must be taken as soon as possible.
The second is to prevent further damage to the house and personal injury. Different preventive measures should be taken according to the different location and damage degree of the house. Houses located on or under landslides are very vulnerable to major damage, so don't live; Don't live in a house that has been seriously damaged but hasn't collapsed.
Third, bungalows and buildings take different preventive measures. Houses that are undamaged, slightly damaged and far from the source of secondary disasters can move in, but preventive measures should be taken.
People who live in bungalows should open doors and windows, be vigilant and flee the house in time when they feel the ground shaking; People who live in buildings should be prepared in advance. If there is an earthquake, don't jump off a building, take an elevator, etc. In an emergency, lie under the bed, in a small-span house or curl up in a narrow space between two tables, and evacuate quickly after the earthquake.
3. Governments at all levels should raise their awareness of earthquake prevention.
Leaders at all levels should raise awareness of the dangers of earthquakes and strong aftershocks, correctly identify earthquake rumors and information, and guide the masses and their own personnel to effectively prevent earthquakes and stabilize society; Strengthen the training of teachers and students in the school, improve their awareness and skills of avoiding aftershocks, so as to facilitate organized shock absorption and reduce casualties when strong aftershocks occur.
4. Guide the public to consciously master the knowledge of earthquake prevention.
The knowledge of earthquake prevention and shock absorption is very rich, including the basic knowledge of earthquake, the knowledge of correctly identifying earthquake rumors, the knowledge of shock absorption in various situations, and the knowledge of self-help and mutual rescue in case of injury. First, strengthen the publicity of popular science to the public and guide the public to take the initiative to master it;
Second, it is necessary to guide families to prepare emergency plans and carry out family emergency avoidance, evacuation and evacuation drills; The third is to carry out emergency hedging drills under various conditions.
5. Strengthen preventive measures.
In view of the possible disasters caused by strong aftershocks, plans should be made in advance. The earthquake department should strengthen the prediction of strong aftershocks and promptly notify all departments to do a good job in response. Once there is a strong aftershock forecast, all units immediately start the plan and take measures.
