Abstract

This study presents a comprehensive assessment of landslide susceptibility in Chin State, Western Myanmar, focusing on the influence of environmental factors such as rainfall patterns, topographic features, and geological characteristics. Through spatial analysis and statistical inference, strong correlations were identified between these factors and landslide occurrences. The significant correlations revealed robust correlations between rainfall intensity and landslide occurrences, with Pearson correlation coefficient of 0.806, Kendall’s tau_b coefficient of 0.908, and Spearman’s rho coefficient of 0.979. Moreover, topographic features such as flow direction and elevation significantly impacted landslide dynamics, with converging flow patterns and steep slopes contributing to heightened susceptibility. These findings underscore the importance of integrating these insights into risk mitigation strategies and infrastructure planning efforts in Chin State. Urgent proactive measures are needed to safeguard vulnerable communities and critical infrastructure, particularly in light of the increasing trend in landslides and flooding incidents observed over the past decade.
