Earthquake damage level
Earthquake damage index
Level 1: largely intact; bearing and nonbearing component in good condition or several nonbearing components have minor damage and can continue to be used without repair.
0–0.1
Level 2: minor damage; several bearing components have visible cracks; nonbearing components have obvious cracks; several nonbearing components suffer severe damage and can continue to be used after general repair.
0.1–0.3
Level 3: moderate damage; majority of bearing components have invisible cracks; minority of bearing components have obvious cracks; several nonbearing components suffer severe damage and can continue to be used after general repair.
0.3–0.55
Level 4: serious damage; majority of bearing components suffer severe damage; nonbearing components exhibit local collapse; it is hard to repair the house.
0.55–0.85
Level 5: destruction; majority of bearing components suffer severe damage; it is impossible to repair the house.
