震级表示的是地震释放能量的大小,烈度指的是地表破坏程度的大小。这是一对相关联的两个概念。在一般情况下,震级越大,地震烈度就越高。同时,震级与烈度的关系还与下面几个因素有直接关系: 1.与震中距离有关。一次地震所释放的弹性波随距离而衰减,离震中越近,破坏越严重,其烈度值越高;距震中越远,破坏就越轻,其烈度值就越低。如1976年唐山7.8级大地震,唐山(震中区)烈度值为10—11度,而距唐山有一
Earthquake magnitude is the size of the energy released by the earthquake, intensity refers to the size of the extent of damage on the ground. This is a couple of related concepts. In general, the larger the magnitude, the higher the seismic intensity. At the same time, the relationship between magnitude and intensity is also directly related to the following factors: 1. The distance from the epicenter. The elastic wave released by an earthquake attenuates with distance, and the closer it is to the epicenter, the more serious the damage is. The higher the intensity is, the farther it is from the epicenter is, the lighter the damage is and the lower its intensity is. Such as 1976 Tangshan 7.8 earthquake, Tangshan (epicenter area) intensity of 10-11 degrees, while there is a Tangshan
