1 NPO Loei Fund for Nature Conservation and Sustainable Development 2 Institute of Industrial Science, The University of Tokyo 3 Public Works Research Institute 4 21 Disaster Reduction and Human Renovation Institution Text-based information using mobile phone would be useful to warn public accurately and promptly. However, there is little practical research being done to examine its effectiveness especially for rural mountainous areas. This research therefore conducted a demonstration experiment and a questionnaire survey at the area in Thailand to observe how disaster information disseminated with Short Message Service (SMS) broadcast reaches and spreads among local residents. Through the research, it would appear that SMS has a potential to be an effective mean for improving current systems in the area including use of loud speaker to warn the local residents. Keywords: disaster warning, mobile phone, short message service, loud speaker, rural mountainous area,
