Landslides In Northeast India : Cyclone Remal
The Cyclone Remal caused landslides in the northeastern region of India causing several casualties, highlighting the need for multi-hazard disaster resilience. While early warnings for cyclones have improved, landslides still remain a challenge.
- A landslide can be defined as the movement of a mass of rock, debris, or earth down a slope.
- They are a type of mass wasting, which denotes any downward movement of soil and rock under the direct influence of gravity.
- Landslide encompasses five slope movement modes: falls, topples, slides, spreads, and flows.
- Causes:
- Slope movement occurs when forces acting downward (mainly due to gravity) exceed the strength of the earth materials that compose the slope.
- Landslides are caused due to three major factors: geology, morphology, and human activities.
