What we know
Joshimath began sinking in 2023. In August 2025 a flash flood struck Dharali. Unsafe construction is part of the problem.
Open questions
- Which towns and roads lie in high-risk zones, and what building is still allowed there?
- How much is spent on disaster warning systems, and do they reach villages in time?
- What rules on building near rivers and slopes have worked in other mountain regions?
