earthquake intensity mainly reflects the degree of earthquake damage caused by the ground and houses, including building damage, natural landscape changes, etc. my country's intensity is divided into 12 levels. The higher the level, the heavier the damage. Among them, buildings with an intensity of six degrees or above will suffer from varying degrees of damage.
