A community-based DRR system provides risk investigation, training and information analysis . Sharing information enhances establishment of such a system and contributes to disaster prevention . One example is an online mapping tool, which has been developed by volunteers . Social media enables the population to access real- time information on a disaster , raises situation awareness  and empowers communities towards appropriate emergency actions . Among the various forms of social media, Twitter is widely used as a social sensor to detect what is happening in a disaster event . Accuracy of information on Twitter has been proved in collecting local details about floods ; however, it has been noticed that Twitter generates rumours as well . Artificial intelligence is expected to reduce human error when they operate a decision-making system . Since technologies supporting DRR completely depend on electricity, the loss of power supply and communication constrains the recovery work in disaster- affected areas .
