UI/UX Design of a Real-Time Earthquake Early Warning System for Optimizing Emergency Information Delivery

Abstract

The Earthquake Early Warning System (EEWS) plays a highly strategic role in minimizing casualties and material losses by delivering alerts as quickly as possible before destructive seismic waves reach the surface. Although earthquake sensors and detection technologies have advanced significantly, system effectiveness is often hindered by non-intuitive interface designs, unclear information hierarchy, and poor user experience during emergency notifications. This study proposes the design of a real-time earthquake warning interface using a User-Centered Design (UCD) approach to optimize the rapid and comprehensible delivery of emergency information. The prototype interface was developed using Figma and evaluated through heuristic evaluation and usability testing involving 32 respondents. The results show that the redesigned interface improved users’ decision-making speed by 41% and achieved a System Usability Scale (SUS) score of 86.7, categorized as “Excellent.” These findings emphasize that well-implemented UI/UX design significantly enhances the effectiveness of emergency communication systems. Future work is recommended to incorporate multimodal alerts, artificial intelligence–based recommendations, and cross-platform integration at a national scale.
