Is the magnitude 3 earthquake serious?

Best answer: The magnitude 3 earthquake is not serious, and the released energy is about 2.0× 10 9 Joule, which has no destructive power to buildings, so it belongs to inductive earthquake. In seismology, there is a classification according to the magnitude of vibration and the degree of damage, which divides earthquakes into micro-earthquakes, inductive earthquakes, destructive earthquakes, severely destructive earthquakes and severely destructive earthquakes that cause great losses. Earthquake is one of them.

Earthquakes are classified into 12 grades.

At the first level, people did not feel the vibration.

Second, people can feel shaking in tall buildings.

At the third level, it can be felt indoors on the ground, and the suspended object also shakes.

Fourth, even the car shakes. If it is serious, cracks will appear in the wooden wall or window frame.

In the fifth stage, the liquid in the container spills out, and the sleeper will be awakened and the small object will be displaced.

Sixth, the pictures on the wall will fall, the furniture will move, and people will flee to the outside for fear.

Seventh, people will stand unsteadily, and water waves will appear in the pond.

The eighth stage, the masonry wall is partially broken and collapsed, and the branches are broken.

Grade 9, it is very serious, the underground water pipe breaks, cracks appear on the ground, small buildings collapse and so on.

Level 10, cracks appear in reservoirs, bridges are destroyed, railways are distorted, etc.

At the eleventh level, all underground water pipes and sewer systems were destroyed.

Level 12, total destruction, even the boulder is shaken and displaced.
