This study aimed to analyze the roles of public sector and mass media in management communication for natural disasters in Songkhla Province. In part of the public sector, the effectiveness of communication management plan and development were considered in every occasion of disasters. In part of mass media, the roles of present functions and information towards natural violence were studied. This qualitative research data was collected using in depth interviews and focus group discussions. Data were analyzed and the results were reported. The concepts of David K. Berlo (1960) were used as a guide for data analysis and showed that the source formed by single command. Initial disaster messages were screened by the Disaster Management Board of the Province and then the Provincial Governor of Songkhla Province has taken supremacy to be the informant of disasters. As the situation rapidly changes, the disaster emergency message needed to be precisely written and promptly announced. A critical disaster discovery was publicized by national and regional media channels including television and radio station broadcasts, especially three local radio stations, so the population at risk (or receivers) prepared to survive before a disaster strikes. Meanwhile, during the catastrophe stage, fact finding reports by mass media were important for the receivers. Mass media also have important roles in mobilizing assistance from wider public for victims of the disaster.
