Quantization table of earthquake damage level.

Earthquake damage levelEarthquake 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.0.85–1
