2. Why Delhi-NCR Is Seismically Vulnerable
2.1 Seismic Zone IV
Delhi-NCR lies in Zone IV, a high-seismic-risk region per Bureau of Indian Standards Times of India+12The Indian Express+12Hindustan Times+12.
2.2 Active Fault Lines
Key fault systems beneath and around Delhi include:
- Delhi-Haridwar Ridge, Delhi-Moradabad Fault
- Mahendragarh–Dehradun, Sohna, and Great Boundary Fault, among others Hindustan Times+1Hindustan Times+1.
2.3 Tectonic Pressure
The Indian Plate continues pushing north into the Eurasian Plate at ~47 mm/year, building stress and triggering quakes Wikipedia+1Wikipedia+1.
2.4 Historical Precedent
While Delhi hasn’t seen quakes above magnitude 5 in the past decade, lighter tremors (4.0–4.6) have occurred—e.g., a 4.0 quake near Dhaula Kuan in Feb 2024 and a 4.1 event in 2022 .

5. Safety & Preparedness: Do’s and Don’ts
Before a Quake
- Build an emergency kit: water, canned food, meds, flashlight, first aid, important documents
- Ensure Google Earthquake Alerts are enabled (with location, Wi-Fi, background accuracy active) Navbharat Times
- Draft a family safety plan: meet-up location, mosque/church/school as a rally point Earthquake in Delhi
During a Quake
- Duck–Cover–Hold: Hide under sturdy furniture or in doorframes
- If indoors, avoid windows, glass, heavy furniture

6. Building & Infrastructure Safety
6.1 Construction Codes
- IS 1893:2002 mandates seismic design; new buildings in Zone IV must comply
- Buyers should demand seismic compliance certificates and structural plans Wikipedia
6.2 Retrofitting
- Older constructions lack seismic reinforcement
- Implement retrofitting (shear walls, steel braces) to improve resilience
6.3 Local Initiatives
- Delhi’s Disaster Management Authority periodically audits and identifies high-risk zones
- Public bodies and builders are urged to adhere to seismic norms
7. Long-Term Measures for Delhi-NCR
- Widespread seismic awareness campaigns
- Provisioning Earthquake Detector Apps (e.g., IndiaQuake) linked to NCS data India Today+1Times of India+1Hindustan Times+2Wikipedia+2The Economic Times+2
- Stricter enforcement of BIS codes on new constructions
- Regular safety drills at schools, offices, and communities
- Early warning systems to detect P‑waves and prompt immediate public action
