Vulnerable building structures: Rain Induced collapses in Himachal Pradesh

Across Himachal Pradesh, a state in India, devastating building collapses have occurred due to heavy rains, leading to landslides and flash floods during this year's monsoon season. In August alone, the death toll reached 120 people. One incident spotlighted the danger posed by rain-weakened structures when at least eight vacant buildings collapsed in Anni, Kullu.

Rainfall Havoc

Intense rains triggered landslides and floods, causing significant damage across the state. The month of August witnessed a grim toll of 120 deaths due to these natural disasters. Since the onset of the monsoon in June, the total casualties have amounted to 238. Chief Minister Sukhvinder Singh Sukhu reported massive losses of ₹10,000 crore as a result of the widespread destruction.

Vulnerable Settlements

Areas near water bodies and streams have been particularly susceptible to collapses. Recent incidents include two deaths and eight collapsed houses in Shimla's Krishna Nagar, and a landslide that buried around 30 houses in Solan's Shamti village. An investigative committee of experts probed a tragic incident where a landslide claimed 17 lives on August 15. Their preliminary findings attribute the event to loose soil strata. The committee's anonymous member emphasized the role of soil stability in land sinking incidents.

Challenges and Solutions

The National Disaster Management Authority highlighted that a substantial 38,000 sq km area in the state is prone to landslides, with 7,800 sq km categorized as high-risk zones. Experts advocate for revised land use policies and urban planning that prioritize geological dynamics. Collaborative efforts between governments, local authorities, and geological experts are recommended to ensure sustainable urban development.

Caution Against Uninformed Construction

Geological knowledge is crucial when constructing structures near water bodies. The improper development was evident in the case of buildings positioned along streams in Shimla. Experts stress the importance of assessing sewage disposal infrastructure, particularly in rapidly growing areas like Shimla, where water consumption exceeds proper distribution.The series of building collapses in Himachal Pradesh underscores the urgent need for comprehensive planning and informed construction practices. A geology-based approach, collaborative efforts, and sustainable policies are imperative to safeguard lives and property in the face of rain-induced disasters.
