🔆 Case Study: Sinking of Joshimath

📍 Joshimath, located in Chamoli district of Uttarakhand, is facing severe land subsidence driven by both natural vulnerabilities and human-induced stress.

✅ Key Geophysical Factors
• Located in a high-risk seismic zone (Zone V).
• Lies over active fault lines — Vaikrita Thrust and Main Central Thrust.
• Built on geologically unstable terrain of old landslide debris.

✅ Human-Induced Stress
• Unregulated construction and large-scale hydroelectric projects have disturbed the fragile ecosystem.
• Increased rainfall and blocked drainage systems further exacerbate ground instability.

📍 Way Forward
✅ Urgent steps needed include:
• Regulated development
• Scientific and geological reassessment
• Seismic risk mitigation planning

Protecting Joshimath demands a balance between ecology and development.
