• Abstract:

  Effective Disaster Management Requires Rapid, Coordinated Communication Among Citizens, Relief Organisations, And Administrative Authorities. Existing Systems Are Fragmented, Lack Real-time Geographic Awareness, And Fail To Provide Emergency Navigation Assistance To Affected Individuals. This Paper Presents DisasterAlert, A Progressive Web Application (PWA) Built On A Fully Serverless Amazon Web Services (AWS) Architecture, Designed To Address These Critical Deficiencies. The System Implements Role-based Access Control Via Amazon Cognito, Supporting Three User Roles: Citizen, NGO, And Administrator. A Real-time Disaster Map Powered By Leaflet.js And OpenStreetMap Visualises Geotagged Incident Reports Submitted By Citizens. An Emergency Navigation Module Integrates The OpenStreetMap Overpass API For Hospital Discovery And The Open Source Routing Machine (OSRM) For Turn-by-turn Navigation, Enabling Citizens In Disaster Zones To Locate And Route To The Nearest Medical Facility. The Backend Comprises AWS Lambda Functions, Amazon API Gateway, And Amazon DynamoDB, Deployed Via Amazon S3 And Amazon CloudFront. The System Was Fully Developed And Deployed Within A Seven-day Period. Evaluation Results Confirm All Functional Requirements Are Satisfied, With Lighthouse Audit Scores Exceeding 87/100 And Zero Operational Cost Under AWS Free Tier. DisasterAlert Demonstrates The Viability Of Rapid, Cost-effective, Cloud-native Disaster Management Solutions.
