The importance of using multiple communication channels in disaster environments


To ensure an effective communication with citizens so that all citizens are aware of emergency and disasters practitioners state that multiple communication channels should be used in case one fails or citizens do not use one of the communication channels used: “The communication can be sent through but it needs other types of communication that are parallel, maybe someone will receive it twice. I think that it’s very complicated to be selective, sending a communication with Twitter or in another way. It’s better to proceed with systems that overlap one another” (G6; R1 - see source document for full reference). However, such overlapping may also be seen as a strength, given that cultural groups and cultural factors overlap as well. Accordingly, it may be preferable to use multi-channel communication to ensure that all cultural groups are reached, despite the risk of sending redundant information, perceiving social media and apps as complementary information tools.
