Tectonix Engine
Bangladesh Earthquake Simulation Platform
A comprehensive web-based platform for simulating earthquakes on real tectonic structures in Bangladesh, enabling better understanding of seismic risks and disaster preparedness.
How Tectonix Works
Select Fault Line
Choose from 5 major tectonic structures: Dauki Fault, Madhupur Fault, Tripura Fold Belt, Shillong Plateau, or Megathrust Zone
Configure Parameters
Set earthquake magnitude (M3.0-9.0), focal depth (5-50km), and choose attenuation model (GMPE)
Simulate Earthquake
The engine calculates ground shaking intensity (MMI/PGA) for all 64 districts using distance-based attenuation
Analyze Results
View interactive maps, affected population estimates, district-wise intensity tables, and export reports

Population Data
District-level population estimates from Bangladesh Bureau of Statistics (BBS)
Attenuation Models
Peer-reviewed Ground Motion Prediction Equations from seismological literature
Simulation Modes
Realistic Mode
Simulates earthquakes using scientifically constrained magnitudes based on fault characteristics and historical seismicity.
- ✓ Uses maximum theoretical magnitude per fault
- ✓ Based on geological constraints
- ✓ Recommended for research and planning
Hypothetical Mode
Explore "what-if" scenarios by manually selecting any magnitude value to test extreme or unlikely events.
- ✓ User-defined magnitude (M3.0 - M9.0)
- ✓ Scenario testing and education
- ✓ Stress-test infrastructure resilience
Scientific Foundation
The simulation engine uses Ground Motion Prediction Equations (GMPEs) to calculate seismic wave attenuation with distance. Peak Ground Acceleration (PGA) is converted to Modified Mercalli Intensity (MMI) for intuitive damage assessment. All calculations account for hypocentral distance and focal depth variations.

Important Disclaimer
Tectonix Engine is an educational and research tool developed for academic purposes and public awareness. The earthquake simulations provided by this platform are based on simplified Ground Motion Prediction Equations (GMPEs) and should be interpreted with appropriate caution.
Limitations & Considerations:
- Simulations use simplified attenuation models
- Actual earthquake effects depend on many factors not modeled here
- Local soil conditions, building quality, and population density vary significantly
- Results should not be used for critical infrastructure planning or emergency response
- This tool does not predict when earthquakes will occur
For official seismic hazard assessments, building codes, and emergency preparedness planning, please consult:
- Bangladesh Meteorological Department (BMD)
- Department of Disaster Management (DDM)
- Professional seismologists and geological surveys
- Licensed structural engineers for building safety
By using this platform, you acknowledge that the developer and affiliated institutions are not liable for any decisions made based on these simulations. This is an academic project intended to promote earthquake awareness and scientific understanding.
