Magnets can predict earthquakes? Without scientific basis

After the devastating Wenchuan Earthquake, a 9-magnitude earthquake struck Japan, causing many people to talk about "shock" changes. Some experts said that the current crust movement has entered an active period and the earth has entered the earthquake year. Some netizens worry that earthquakes may also occur in the places where we live.
Yesterday, the netizen “powered himself” in the living room of the new newspaper and introduced a method of earthquake prediction: Hang a magnet on a rope with a high place, and place a large iron block on the floor tile or an iron basin below. Before the earthquake, the earth's magnetic field changes dramatically and the magnet loses its magnetism. Iron pieces will fall and fall on the ground or pots. It is said that this method will give early warning within 10 minutes to tens of seconds before the house is not shaken. If the iron block falls, there will be a major earthquake.

Is this method of earthquake prediction scientific? Yesterday, Zhu Kechang, director of the Earthquake Prevention and Disaster Reduction Section of the Earthquake Administration of Yiwu City, heard that after hearing, the country currently uses precision instruments and equipment for earthquake prediction. There is no scientific basis for predicting earthquakes by hanging magnets and iron blocks. Zhu Kechang said that Zhejiang is in a less earthquake-prone area and never had an earthquake of magnitude 6 or higher. Citizens need not worry too much.

Earthquakes in China are frequent. Among them, over 7 earthquakes occurred in 18 provinces (autonomous regions and municipalities directly under the Central Government), accounting for 60% of the provinces (autonomous regions and municipalities directly under the Central Government). However, our province and Guizhou are located in a weak earthquake zone and never experienced more than 6 levels. Strong earthquake.

After the earthquake, how should we deal with it scientifically? Zhu Kechang said that he was calm and calm and impending earthquake. When the earthquake near the evasion, quickly evacuated to a safe, open place after the earthquake, which is a better method of emergency shock. When emergency evacuation, try to reduce the body's center of gravity, you can take the correct shock posture such as squat, squat or sit down; pay attention to protect the head, neck, eyes, mouth, nose and other important parts. If possible, use nearby objects such as pillows, bedding, etc. on top of the head; lower your head and eyes closed to prevent injury from foreign objects; use a wet towel to cover your mouth and nose to prevent dust and gas from intruding. To avoid being strong inside the room, not easy to dump, or underneath the objects that can cover the body, it is best to choose a small space with support for shock absorption, such as a load-bearing corner or a low, sturdy furniture edge; under a sturdy table (side) or under the bed (side).
