Why in news
Landslides in North Bengal and Mizoram and heavy rainfall in Uttar Pradesh highlight the increasing frequency of extreme weather events and geological hazards in the Himalayan and Northeast regions.
Background
Delhi recorded a maximum temperature of 38.6°C on Monday, exceeding normal levels. Gorakhpur, Uttar Pradesh, recorded the highest rainfall at 85.3 mm during the same period. Telangana has initiated a three-phase plan to mitigate the impacts of El Niño.
Facts for Prelims
- FactGorakhpur recorded 85.3 mm of rainfall during the recent weather event.
- PlaceNorth Bengal and Mizoram are prone to landslides due to fragile Himalayan geology.
- S&TEl Niño is a climate pattern characterized by the warming of surface waters in the eastern equatorial Pacific Ocean.
For Mains
Q. Analyze the geological and climatic factors contributing to the increasing frequency of landslides in the Himalayan region and suggest mitigation strategies.
Dimensions to cover in your answer
- Geological vulnerability: Fragile Himalayan lithology and high seismic activity increasing landslide susceptibility.
- Climate-induced stress: Intensified monsoon patterns and erratic rainfall causing rapid soil saturation and slope failure.
- Infrastructure bottleneck: Lack of landslide-resistant road engineering and early warning systems in hilly terrains.
