Standard of seismic intensity division.
| Seismic intensity | Condition of building collapse | Mean damage index | Earth’s surface status | Concrete | Multilayer brick | General houses |
| VII | 0.00 | 5.47% | 6.00% | 0.11–0.30 | Soft land is cracked; most detached brick chimneys are moderately damaged; riverbank is collapsed. |
| VIII | 0.00 | 12.91% | 15.00% | 0.31–0.50 | Hard land is cracked; most detached brick chimneys are seriously damaged. |
| IX | 5.40% | 25.86% | 33.00% | 0.51–0.70 | Hard land is cracked; most detached brick chimneys are collapsed; bed rock is cracked; landslide occurs. |
| X | 24.73% | 50.79% | 88.00% | 0.71–0.90 | Landslide and rupture appear; most detached brick chimneys are collapsed from the root; bedrock arch is destroyed. |
| XI | 50.00% | 80.00% | 95.00% | 0.91–1.00 | The earthquake ruptures continue long; a large number of landslides occur. |
