🔆 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.

📝 Mains GS1 Q
Q. The crisis in Joshimath highlights the tension between environmental fragility and developmental pressures in Himalayan towns. Analyse the causes of the crisis and suggest sustainable solutions.

🔆 Mantle Plume – Geography & Disaster Management

📍 A mantle plume is a localized, upwelling column of hot magma rising from deep within the Earth’s mantle, possibly from the core-mantle boundary. These plumes are thought to be stationary and independent of tectonic plate boundaries.

✅ Key Features
🔹 Origin: Deep mantle or core-mantle boundary (~2,900 km depth)
🔹 Nature: Buoyant and hot, it melts the overlying lithosphere, forming volcanic hotspots
🔹 Examples:
 ➤ Hawaiian Islands – Pacific Plate moving over a plume
 ➤ Deccan Traps – Result of the Réunion plume

✅ Importance
🔹 Explains intraplate volcanism (volcanoes away from plate boundaries)
🔹 Helps understand continental flood basalts and plate movements

🔆 Glacial Landforms

📍 Formed by erosion and deposition as glaciers move under gravity. Key landforms:

📍 Erosional Landforms:
✅ Cirques – Bowl-shaped depressions at high elevations
✅ Nunataks – Rocky peaks protruding through glacier ice
✅ Arêtes – Sharp ridges between glaciers
✅ Horns – Pointed peaks carved by multiple glaciers
✅ Crevasses – Deep cracks in moving glaciers
✅ Fjords – Long inlets where glacial valleys meet the sea (📝UPSC 2023)

📍 Depositional Landforms:
✅ Moraines – Ridges of sediments deposited by melting glaciers
✅ Glacial Till – Unsorted rock mix left behind by glaciers
  🔹 Glacial Flour – Finest sediment causing cloudiness in glacial rivers
✅ Glacial Erratics – Large boulders deposited far from their origin

📍 Significance:
✅ Clues to past climates (e.g. glacial boulders in Talcher, India → ancient glaciation)

📝 Prelims Q:
Which of the following are correctly matched with glacial origin?
1. Cirques – Bowl-shaped depressions
2. Moraine – Glacial deposition
3. Arêtes – Sharp ridges between glaciers
4. Fjords – River valley erosion

A. 1, 2 and 3 ✅
B. All four
C. 2 and 3 only
D. 1 and 4 only

📌 Correct: A (Fjords = glacial, not river erosion)

📄 Mains Q (GS1):
Explain the formation and significance of glacial landforms. Highlight how these features act as indicators of past climatic changes. (150 words)

🔆 Stampedes in India

📍 Definition:
✅ A stampede or crowd crush occurs when sudden panic or crowd pressure leads to uncontrolled movement, often triggered by perceived danger or lack of space.
✅ The NDMA (National Disaster Management Authority) classifies stampedes as man-made disasters.

📍 Recent Incidents:
✅ Bengaluru – RCB’s IPL win celebrations
✅ New Delhi – Railway station rush during Kumbh Mela
✅ Prayagraj – Kumbh Mela stampede

📍 Why India is Prone to Stampedes:
✅ Weak Accountability: Venues often exceed safe limits; lack of barricades & poor administrative oversight.
✅ Poor Coordination: No integrated planning between police, organizers & local administration.
✅ Limited Tech Use: Inadequate real-time monitoring, CCTV analytics, and crowd sensors.
✅ Socio-Structural Causes: High population density, increased pilgrimage events, poor infrastructure, panic behavior, and untrained personnel.

📍 Way Forward:
✅ Deploy real-time surveillance, drones, and AI-based crowd-density tools.
✅ Introduce online passes/registrations for major events.
✅ Enforce strict accountability for organizers and officials violating safety norms.
✅ Improve infrastructure: wider exits, non-slip surfaces, clear pathways, and lighting.

📍 NDMA Guidelines for Crowd Management:
✅ Traffic Control: Restrict vehicle access near venues.
✅ Clear Signage: Entry, exit & emergency route maps.
✅ Barricades & Queues: To regulate movement and avoid congestion.
✅ Surveillance: CCTV and police deployment for real-time monitoring.
✅ Space Management: Remove encroachments, ensure open evacuation routes.
✅ Preparedness: On-site medical aid, fire prevention, and public awareness drives.

🧩 Mains Question:
➡️ “Stampedes in India are more a failure of governance than of crowds.” Discuss with reference to NDMA guidelines.

🔆 Revised Seismic Zonation Map (BIS 2025)

📍 What’s New?
✅ India updates Earthquake Design Code (BIS 2025) with a revised Seismic Zonation Map
✅ Based on faults, max probable events, tectonics, lithology, attenuation etc.

📍 Key Changes in Zonation
✅ Earlier: 4 zones — II, III, IV, V
✅ Now: New highest-risk Zone VI created
• Entire Himalayan arc placed in Zone VI (earlier split between IV & V)
✅ Boundary towns between zones now automatically included in the higher-risk zone
✅ Mapping now focuses on geology, not administrative borders

🔆 India’s Earthquake Vulnerability
✅ 61% of land in moderate–high hazard zones (earlier 59%)
✅ 75% of population now lives in seismically active regions
✅ Implications:
• Push for retrofitting in high-risk areas
• Restrict expansion on soft sediments/near active faults
• Uniform building standards in Himalayan states

🔆 Government Strategies
📍 NDMA & SDMAs
✅ NDMA frames policies, SDMAs implement state-level disaster plans

📍 National Seismological Network
✅ Monitors quakes
✅ Supports development of early warning systems

🔆 Causes of Crowd Disasters

📍 Structural Issues
✅ Weak/illegal structures, narrow passages, vertical stairs
✅ Hawkers, parking & encroachments obstruct movement

📍 Fire/Electric Hazards
✅ Makeshift kitchens, faulty wiring
✅ Misuse of firecrackers → sudden fires & panic

📍 Crowd Behaviour
✅ Overselling tickets, unmanaged surges
✅ Panic from rumours, sudden rush, freebies/celebrity sightings

📍 Inadequate Security
✅ Too few security personnel
✅ Excessive force (e.g., teargas) causing stampede-like panic

📍 Poor Administrative Coordination
✅ Weak coordination between police, fire services, shrine/event management, & civic bodies
