Insights from Cyclone Ditwah: Recommendations for Addressing Linguistic Barriers in Sri Lanka’s Disaster Early Warning Systems through Language Technology

Abstract

Disaster early warning systems are critical for reducing loss of life and ensuring timely response during emergencies. However, the effectiveness of such systems depends not only on technological capacity but also on the inclusivity of communication. In linguistically diverse contexts, language barriers can significantly limit access to life saving information. This paper presents insights on the role of technology in enabling multilingual disaster early warning and communication systems in Sri Lanka. Drawing on observations from recent disaster events, specifically the catastrophic Cyclone Ditwah in 2025, and a review of existing policy and operational practices, the paper highlights gaps in language consideration within current disaster management frameworks. By analyzing local gaps, such as the incomplete localization of platforms and evaluating global models like Japan’s J-Alert and India’s SACHET, this study identifies practical, technology driven pathways for inclusion. The paper proposes the integration of AI driven translation, multilingual cell broadcasts, and text-to-speech audio alerts as core infrastructure rather than secondary features. By embedding multilingualism into disaster communication from the planning stage, authorities can ensure that urgency is communicated effectively across all communities, ultimately saving lives through clarity and trust.
