<![CDATA[Indonesia is a country with a high level of disaster vulnerability, including Sumenep Regency in Madura, which routinely experiences floods, droughts, and tornadoes. The people of Sumenep have developed self-mitigation practices based on local knowledge (indigenous knowledge) despite limited disaster literacy and insufficient formal socialization from government institutions. This study aims to analyse how the ethnographic process of communication shapes and reproduces self-mitigation practices as a community resilience strategy. The research uses a qualitative approach with the ethnographic design of communication in the constructivism paradigm. The informants were purposefully chosen, and they were from BPBD, religious leaders, and people who lived in three villages that are likely to have disasters: Kebunagung, Pasongsongan, and Kertasada. We gathered data through passive participant observation, in-depth interviews, and documentation. Then, we analysed the data in relation to the components of communication situations, communicative events, and communicative actions. The results show that practices such as village rokad during floods, istisqa' prayers during droughts, and symbolic rituals of "cutting the wind" during tornadoes are not just spiritual expressions but are cultural communication systems that build social solidarity, transmit risk knowledge, and strengthen collective resilience. Symbol, narrative, and ritual-based communication serve as an adaptive mechanism that organizes the community's response to disaster threats. This research confirms that cultural communication is an important foundation in community-based mitigation and needs to be integrated into formal risk communication policies. This study contributes to the development of community-based disaster communication studies in the context of Southeast Asia.]]>
