This is a conceptual titled “QuakePrep: A Community-Based Framework for Proactive Earthquake Resilience.”
It is structured as a proposal suitable for academic review, municipal planning, or NGO implementation. Date: April 14, 2026 Version: 1.0 Subject Area: Disaster Risk Reduction (DRR), Civil Engineering, Public Policy 1. Executive Summary Earthquakes remain one of the deadliest natural hazards due to their unpredictability and cascading secondary effects (fires, landslides, infrastructure failure). Current early warning systems (e.g., ShakeAlert, J-Alert) provide 5–60 seconds of lead time but suffer from three critical gaps: high infrastructure cost , low public engagement , and post-communication failure when cellular networks collapse. quakeprep
