Steep slope, steep dips of the lithotypes, presence of clay layering in weathered rock types, events of continuous heavy rains, flooding on the slopes and improper land use practices play a major role in the genesis of landslides in the Nilgiris. Recent enhancement in the events of the landslides in the Nilgiris is mainly due to ongoing Seismotectonic activities in Southern Granulite Terrain (SGT) of South India and reactivation of hidden blind shear zones of Nilgiri Hills. Mitigation measures are highlighted.
