After the earthquake in Japan, Narita Airport shook violently. What are the signs before the earthquake?

Tokyo, Chiba and Kanagawa have strong earthquakes. The earthquake was a bit violent ... some of my friends in Tokyo were still sleeping and suddenly woke up ... Fortunately, there were no reports of casualties, but some trams were stopped/delayed. Flights at Tokyo Narita Airport and Haneda Airport are also unaffected. Japanese citizens who are used to earthquakes are very calm. They should go to work and go to school. After all, they are more afraid of not getting on the tram than the earthquake. ...

Earthquake is a natural phenomenon that the earth's crust vibrates in the process of rapid energy release, and seismic waves will be generated in this process. So what are the signs of the earthquake? Let's get to know each other.

The first phenomenon is that all kinds of animals will have some abnormal conditions, because animals are much more sensitive than us, so they can feel some conditions before the earthquake, such as poultry refusing to enter the nest and scurrying about on the ground. There are also some animals that are afraid of humans, but they are not afraid of us. After all, we humans are much milder than earthquakes. ?

The second phenomenon is that there will be some strange sounds coming from underground. The sound is deafening, but we can't find the source of the sound just because it comes from underground. Before an earthquake, there will be a longitudinal wave and a transverse wave. The sound we hear is longitudinal wave. If you hear this sound, run quickly.

The third is to emit some light with very strange colors from underground. It is very abnormal that some light is emitted underground. Be careful when you meet.

The fourth phenomenon is that there will be some fog on the ground. The fog scattered from the ground has various colors and looks strange. If you see such fog, you should pay special attention in recent days, because an earthquake is likely to happen soon. ?

You never know which comes first, tomorrow or the accident. Life and death are in an instant. If you go to bed tonight, I don't know if you can wake up tomorrow. Life is like a dream. Live in the moment. Don't wait until you lose it to know how to cherish it. Life is short. Meet the people you want to see, do what you want to do, live the life you want, love the people you want to love, and pray for the disaster area. ...
