Prof. Abstract The Japan is one of the countries in the world vulnerable to natural hazards because of its geographiclocation. Due to the advances of Internet and mobile technologies, mobile phones with Internet connection and computation capabilities are widely used now a day. The purpose of this paper is to examine the proposed hazard warning mechanism using the Location Based Service technology and a hazard information management system to rapidly distribute warning message in a short time while hazard sites are near the system users.. The disaster management system Android application known as MyDisasterDroid determines the optimum route along different geographical locations that the volunteers and rescuers need to take in order to serve the most number of people and provide maximum coverage of the area in the shortest possible time. Genetic algorithm was applied for optimization and different parameters were varied to determine the most optimum route.

Indeed, through the years, the Japan because of its geographic location has been devastated by several natural disasters. It has claimed the lives of thousands of people and damaged billions worth of property. Even with the recurrent calamities, there is still the absence of an efficient disaster management system that will help the people in times of calamities. 2Disaster Management The process of disaster management involves four phases: mitigation, preparedness, response, and recovery. The mitigation phase is the attempt to reduce disaster risks by focusing on long-term measures of eliminating disasters. The preparedness phase is the development of an action plan for an upcoming disaster. The response phase is the mobilization of services and relief when disaster strikes and the recovery phase is the restoration of the affected area to its previous state [2]. 2.1Sahana Foss SAHANA is a free and open source disaster management system. It is a web-based collaboration tool that addresses common coordination problems during a disaster. It is a set of pluggable, web-based disaster management solution that provides solutions to problems caused by the disaster and it is designed to help during the relief phase of a disaster. It has been already deployed in different disaster areas including the Japan during the Southern Leyte Mudslide Disaster in 2006 [3]. At present, more tools are being developed however; the current disaster management system does not include a tool that will aid in the response phase during the disaster. The response phase includes search and rescue operations as well as the provision of emergency relief. In this phase, efficiency is important because during this kind of situation, time is of the essence. A second delay may cause someone’s life. Thus, a system that determines the most optimum route for the volunteers and rescuers to take in order to serve the most number of people and provide maximum coverage of the affected area in the shortest possible time is beneficial. 2.2Using Wireless Mobile Technologies The use of wireless mobile technology in the Japan is prevalent. A study showed that one Filipino in two is a subscriber to a mobile phone service [4] and more than two billion in the world are mobile users [5]. Because of the wide coverage of the mobile phone network, it may be used in the implementation of a disaster management system making it available in everyone’s pocket. A study in Bangladesh established that wireless mobile technologies can be used in disaster information management. Results showed that mobile technology may be used to disseminate pre- disaster warnings and post-disaster announcements, to receive information about relief needs, and to exchange information about health hazard [6]. Also, in disaster information management, geographic locations of those in need are important. Using their mobile phones, their locations can either be determined using the mobile network system or through the use of an integrated Global Positioning System (GPS) included in their phone. 2.2.1Smart Phones and Disaster Response Based on research released by Smartphone Summit, smart phones account for 10% of all cell phone sales and it is still growing and driving more
