PRALAY
Predictive Radar & AI Landslide Alert System
Built by TERRA SHIELD
Mission & Vision
🎯 Our Mission
To predict landslides before they happen — saving lives, protecting infrastructure, and empowering communities across the North Eastern Region with real-time, AI-driven early warnings.
🔭 Our Vision
A future where no life is lost to landslides — because timely warnings reach everyone, everywhere, in their own language, before disaster strikes.
About PRALAY
PRALAY is an AI-powered landslide early warning system designed specifically for the fragile terrain of the North Eastern Region (NER) of India. It combines satellite imagery, rainfall data, ground deformation measurements, and community reports to predict landslide risks in real-time.
The system provides location-wise risk scores through an interactive GIS map, issues multilingual alerts (Hindi + English) to both local users and authorities, and ensures data integrity through blockchain-backed records. Its 3D Digital Twin visualizations enable decision-makers to simulate "What-If" scenarios and plan proactive evacuations.

Key Features
- Explainable AI Risk Prediction — Analyzes rainfall, soil moisture, slope, and historical data to predict risk and explains the key factors behind it.
- Smart Response Prioritization — Identifies high-risk villages, roads, and infrastructure that need immediate attention.
- GIS Risk Mapping — Visualizes vulnerable zones through interactive risk-based heatmaps.
- Early Warning System — Sends timely multilingual alerts (Hindi + English) to authorities and communities through app and SMS.
- Low-Network Support — Enables offline reporting and syncs data automatically when connectivity returns.
- 3D Digital Twin — Interactive 3D terrain model with What-If simulation for scenario planning.
- Blockchain Security — Tamper-proof prediction records stored on an immutable ledger.
- Crowdsourcing — Community-driven reporting to validate AI predictions and capture ground truth.
