SCL Social was asked to advise on how to implement a national warning to beach-goers and waterfront home owners in the event of a tsunami. It was crucial that the necessary information reached the widest possible audience without losing credibility. Simply sending a text to every mobile phone in the region suggesting recipients turn on their radios and move to higher ground immediately was not enough. The message needed to be substantiated by including a real-time reference. This was achieved by explaining in the message that verification would be provided by the presence of fighter jets flying up and down the coastline – an action that was readily demonstrable in a short space of time.
