The magnitude of an earthquake is a measure of the magnitude of the earthquake given by the instrument. It is a grade that divides the magnitude of the energy emitted by the source. And the intensity of the impact of the engineering building is determined by the feeling of people during the earthquake or the degree of reaction of the utensils after the earthquake, the degree of damage to the engineering building, and the change of the ground surface in the absence of instruments Macro scale. Based on the above definition, Which of the following statements is true:. ['The greater the magnitude of the earthquake, the stronger the corresponding intensity of the earthquake.', 'An earthquake has only one magnitude and one intensity.', 'The closer to the source, the larger the magnitude and the stronger the intensity.', 'The more severe the surface damage, the stronger the earthquake intensity.']
