Mr Li Siguang passed away on 197 1. Before his death, there was no discussion about the so-called "four major earthquakes" in seismology, and there was no legend of "four major earthquakes" in society.

In the mid-1970s, especially after the Tangshan earthquake, the term "four major earthquakes" began to spread in the society. Over the years, there has been a folk saying that "Li Siguang predicted four major earthquakes". In fact, this fourth XX is a basket, which is generally an area where earthquake rumors spread, and it is often frequently transformed into a "shot" area in almost all parts of the country.

Therefore, I also want to remind you that any news that an earthquake of a certain magnitude will occur at a certain time and place must be a rumor, and never spread it.

Earthquake escape knowledge

1, bedroom

Never get under it. When a house collapses after an earthquake, a triangular space is sometimes formed indoors. These places are relatively safe places for people to live and can be called earthquake-proof spaces. Including a small room under the edge of the bed, under the solid wood furniture, at the root of the inner wall and in the corner. People used to think it was safest to get under the bed, but hiding under the bed was not the best hiding place. The hiding place is near the door. It is best to open the door. You can lean against the doorframe and hold your head, ready to move after the earthquake.

2. Living room

The living room is a place extending in all directions and there is no deposit. In an earthquake, the living room should be regarded as a safe transfer area. Escape gear should be placed in a conspicuous place in the living room, so as to pick up the escape in time.

3. Toilet

During an earthquake, the smaller the room, the safer it is, and the larger the room, the easier it is to collapse. The walls of the bathroom are mostly load-bearing walls, and there are fewer falling objects on the roof, which is relatively safe.
