Consideration of cost-efficient early warning system utilizing existing analogue radio broadcasting in Indonesia

摘要

Early warning systems can increase disaster management capacity. Indonesia worked out the national development policy direction of 2015 – 2019 containing establishment of early warning systems. Japan is operating early warning systems using various ICT systems. Especially an emergency warning broadcasting system to activate corresponding receivers automatically is being operated since 1985. Considering a situation in Indonesia to develop early warning systems from now, an updated early warning broadcasting system can incorporate an earthquake early warning that can provide predicted seismic intensity in each location on the basis of an observed big earthquake prior to actual shaking. The updated system can be cost-efficiently deployed nationwide in Indonesia by combining existing analog radio broadcasting of the public radio network RRI and existing loudspeakers in mosques. Because definitive operation rules need to be established to operate the early warning systems effectively, an operation scenario to provide tsunami warnings is considered as the first step for Indonesia to utilize existing its Warning Receiver System in RRI stations.
