During the Wenchuan earthquake, most stations were playing "Conquer Paradise".
The sad ones include: chaotic red, dreamy snow, and orchids in deep valleys.
Earthquakes (English: earthquakes), also known as ground motions and ground vibrations, are vibrations caused by the rapid release of energy in the earth's crust, during which seismic waves are generated.
Plates on the Earth squeeze and collide with each other, causing dislocation and rupture at the edges and within the plates, which is the main cause of earthquakes. ?
The place where the earthquake begins is called the earthquake source, and the ground directly above the earthquake source is called the epicenter. The place where the ground vibrations of a destructive earthquake is strongest is called the epicenter, and the epicenter is often the area where the epicenter is located. ?
Earthquakes often cause serious casualties, can cause fires, floods, toxic gas leaks, spread of bacteria and radioactive materials, and can also cause secondary disasters such as tsunamis, landslides, collapses, and ground fissures.
According to statistics, more than 5 million earthquakes occur on the earth every year, that is, tens of thousands of earthquakes occur every day. Most of them are too small or too far away for people to feel; there are about ten or twenty earthquakes that can really cause serious harm to humans; there are about one or two earthquakes that can cause particularly serious disasters.
Earthquakes that people cannot feel must be recorded with a seismograph; different types of seismometers can record earthquakes of different intensities and distances. Thousands of various seismic instruments are operating around the world to monitor earthquake movements day and night.
The current level of science and technology is still unable to predict the arrival of earthquakes, and earthquakes will also be unpredictable for a long time to come. The so-called examples of successful earthquake predictions are basically coincidences. Regarding earthquakes, what we should do more is to improve the seismic resistance level of buildings and prepare defenses instead of predicting earthquakes.
