It is a global geological disaster that occurs many times a year, and the size needs to be measured. So, how is size measured?
1. Magnitude. Magnitude is the most basic measure of magnitude. It refers to the amount of energy released and is usually expressed on the Richter scale. The Richter scale is divided according to the amount of energy released, and there is only one magnitude at a time.
Second, the intensity. Intensity refers to the degree of impact on the ground and buildings. It is affected by a variety of factors such as magnitude, depth of the hypocenter, geological conditions, etc. The greater the intensity, the greater the impact on the ground and buildings.
3. The depth of the hypocenter.
Source depth refers to the depth of the hypocenter from the ground at the time of the eventuality. In general, the shallower the depth of the hypocenter, the greater the impact on the ground.
Fourth, the moment of the earthquake.
The moment of the earthquake refers to the specific time when ** occurs. It is important for disaster mitigation and mitigation.
5. Sequence.
A sequence is a series of events that are related to each other. These events may occur in the same location or in the same area, or they may occur in different locations or regions. The study of sequences is of great significance for disaster mitigation.
Sixth, ** waves.
A wave is a fluctuation that occurs when it occurs. It includes two types, longitudinal and transverse waves. Longitudinal waves propagate fast but have less destructive power;Transverse waves propagate slowly, but they are more destructive. Therefore, the study of waves is of great significance for disaster mitigation.
