Key Points

To evaluate the effectiveness and applicability of new AHP-based evaluation sheets for landslide risk classification.
Converted old AHP scores into the new AHP format using mathematical formulas.
Validated the consistency of new scores with aerial photo assessments of landslide risk.
Applied hazard classification thresholds to the new AHP scores for evaluation.
New AHP scores were consistent with the results from the old sheets.
The established hazard thresholds remain applicable with the new AHP scores.
