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. Executive Summary Earthquakes remain one of the deadliest

is a three-tier, open-source framework designed to address these gaps. By combining (1) low-cost MEMS accelerometers, (2) a gamified citizen training protocol, and (3) a LoRa-based mesh network for offline alerting, QuakePrep reduces the per-capita cost of preparedness by an estimated 82% while increasing household plan adherence by 47% (pilot data, simulated). This paper outlines the architecture, pilot results, and a scalable implementation roadmap for medium-to-high seismicity zones. 2. Problem Statement | Current Gap | Consequence | |-------------|--------------| | Centralized EWS (US$ 500k–2M per region) | Excluded low-income and rural communities | | Annual drop drills (low realism, no feedback) | Muscle memory degrades; <20% of households secure furniture | | Cellular dependency for alerts | 70% of cell towers fail in M7+ events (post-event studies: 2015 Nepal, 2023 Turkey) |
