Mizoram, the Capital of Landslide: A Review of Articles Published on Landslides in Mizoram, India

Abstract

Mizoram, a northeastern hilly state of India, suffers from heavy landslides every year during monsoon season. Geologically, Mizoram has been formed in the tertiary era predominantly made of unconsolidated sandstone and shale, which are the dominant rock types in these areas. Unplanned and non-scientific urban sprawls are the triggering factors of landslides in Mizoram. Various researches have been conducted on landslide susceptibility analysis and slope instability. The present work presents a review of various such research works conducted in Mizoram to understand the overall nature of landslide's geological, geomorphological, and anthropological aspects. The review revealed that most of the landslides in Mizoram happen along the roadside and are rainfall induced. So, government policy and PWD must consider various factors like slope holding capacity, geological strength, and rainfall distribution at the time of road construction and expansion. We hope the present work will help the researchers, and planners take proper steps toward slope stability in Mizoram.
