In Pics: From Himachal Pradesh To Sikkim Deadliest Landslides Ever In Indian Hills
In 2025, many states in India, especially those with hills and mountains, were hit by severe landslides because of unusually heavy and unpredictable monsoon rains. These landslides occurred due to the sudden cloudbursts and continuous rainfall. Landslides happen when a slope is already unstable and something like heavy rain, melting snow, earthquakes, or human activities disturbs it further.
Mizoram
The monsoon impact on Mizoram was extremely severe. Mizoram experienced many landslides due to heavy monsoon rains, resulting in deaths, the displacement of hundreds of residents, and the destruction of buildings. There have also been problems with roads, with 257 areas where roads are blocked. In addition, three graveyards have been damaged as a result of the landslides.
Arunachal Pradesh
Heavy rainfall has led to flash floods and landslides in several districts of Arunachal Pradesh, severely disrupting normal life, while nine people died in separate incidents. Critical infrastructure, including roads, power lines, and water supply, suffered extensive damage, and agricultural fields were inundated or washed away.
Manipur
More than 56,000 people have been impacted by severe flash floods and landslides throughout Manipur, caused by overflowing rivers and breaches in embankments across the state. The Imphal East district was the worst-affected area in Manipur due to landslides and floods. This region experienced major embankment breaches, particularly at Bashikhong, after the Kongba River overflowed its banks.
Himachal Pradesh
Himachal Pradesh experienced severe landslides triggered by relentless monsoon rains, causing widespread disruption and casualties. The worst-hit area is Mandi district, where multiple cloudbursts and flash floods have destroyed homes, roads, and bridges.
Karnataka
The Karnataka landslides were primarily caused by heavy and incessant rainfall, which triggered hill collapses and soil slips in several parts of the state, especially in coastal and Malnad regions like Mangaluru, Dakshina Kannada, Hassan, and Chikkamagaluru districts. The risk was further increased in places where hillsides had been excavated or deforested, reducing their stability during heavy rain.
Tripura
Tripura experienced severe landslides triggered by unprecedented and extreme rainfall, with rainfall levels rising. Infrastructure was heavily damaged, thousands of locations saw landslides and road blockades, power lines and bridges were destroyed, and train and bus services were suspended.
Sikkim
Sikkim experienced a series of devastating landslides triggered by intense and prolonged rainfall, particularly affecting the Chaten area in North Sikkim. The event also caused significant infrastructure damage, with roads blocked and bridges destroyed.
Meghalaya
The landslides in Meghalaya caused by the recent heavy rains have been severe and deadly, resulting in significant loss of life, destruction of infrastructure, and widespread disruption. Authorities are actively engaged in rescue and relief, but the situation remains critical.
