TsunamisTsunamis remain a significant threat worldwide, necessitating early warning systemsEarly warning systems (EWS). Therefore, this study examines the role of youth-led initiatives and integration of Indigenous KnowledgeIndigenous knowledge (IK) in enhancing EWS and strengthening community resilienceCommunity resilience against tsunamiTsunami in KeralaKerala, Tamil Nadu, and Andhra Pradesh in the South Coast of India. This study analyzed tsunami EWS in Indian Coastal areasCoastal areas by integrating review and analysis approaches to understand youth-led programs and IK within the region. The research employed literature review, government reports, and historical records allowing the researchers to gather in-depth understanding of the study. The researchers conducted content analysis in analyzing data, which revealed valuable patterns and underlying insights. The study revealed that youth involvement as active agents of change enhances EWS efficiency through fostering innovative ideas, improved community engagement, and increased trust in disaster preparednessDisaster preparedness programs. Additionally, the findings demonstrate that integrating IK into modern EWS not only enhances their effectiveness but also tailor preparedness strategies to local context. Noteworthy, youth-led campaigns using IK have demonstrated successful methods that communitiesCommunities can use to mitigate this crisis. However, the study highlighted challenges such as limited awareness of risks, young people receiving insufficient support from disaster risk reductionDisaster risk reduction (DRR) programs, and inadequate access to information. Future research should explore pilot programs that integrate youth-led IK models into disaster readiness framework. Therefore, the effectiveness of these programs will allow them to be scaled to other disaster-prone regions.
