The correct answer is: Landslides.
Landslides are a significant threat in Nagaland’s hilly terrain because of the region’s geology and climate. The state is located in the eastern Himalayas, which are a geologically active region. The Himalayas are still rising, and this movement causes the ground to shift and slide. In addition, Nagaland is located in a monsoonal climate, which means that it experiences heavy rains during the summer months. These rains can cause the ground to become saturated and unstable, which can lead to landslides.
Landslides can have a devastating impact on people and property. They can bury homes and businesses, block roads and railways, and damage infrastructure. In some cases, landslides can even cause deaths.
There are a number of things that can be done to reduce the risk of landslides in Nagaland. These include:
- Reducing deforestation: Deforestation can destabilize the ground and make it more prone to landslides.
- Reducing soil erosion: Soil erosion can also destabilize the ground and make it more prone to landslides.
- Building better infrastructure: Better infrastructure can help to protect people and property from landslides. This includes things like building roads and railways that are designed to withstand landslides, and building dams and reservoirs to control flooding.
- Educating people about the risks of landslides: Educating people about the risks of landslides can help them to take steps to protect themselves and their property.
Landslides are a serious threat in Nagaland, but there are a number of things that can be done to reduce the risk. By taking steps to reduce deforestation, soil erosion, and building better infrastructure, and by educating people about the risks of landslides, we can help to protect people and property from this devastating hazard.
The other options are also geological hazards, but they are not as significant a threat in Nagaland as landslides. Floods can occur in Nagaland, but they are not as common as in other parts of India. Droughts are also a possibility, but they are not as severe as in other parts of the country. Heatwaves are not a significant threat in Nagaland.
