Landslides are a common natural hazard in both the Himalayan region and the Western Ghats, but the causes of landslides in these two regions are different.
In the Himalayan region, the main cause of landslides is tectonic activity. The Himalayan mountain range is located in a zone of active tectonic activity, and this activity can cause the ground to shift and destabilize, leading to landslides. Earthquakes are also a common cause of landslides in the Himalayan region.
In the Western Ghats, the main cause of landslides is heavy rainfall. The Western Ghats receive high levels of rainfall, particularly during the monsoon season, and this can cause the soil to become saturated and unstable, leading to landslides. Deforestation and land use change are also contributing factors to landslides in the Western Ghats. The removal of vegetation and the alteration of natural land cover can increase the risk of landslides by reducing the ability of the soil to absorb water and by increasing the flow of runoff.
Overall, the causes of landslides in the Himalayan region and the Western Ghats are different, but both regions are vulnerable to this natural hazard. Understanding the specific causes of landslides in these regions is important for developing effective strategies for landslide prevention and management.
