Social media use in March 2011 Japanese Crisis: Impact on emergency preparedness advocacy
Abstract
Content analysis was used to gather nearly 6 months of Twitter messages, which were organized using Radian6 to ascertain responses about emergency preparedness before, during, and after the March 2011 crisis in Japan. This descriptive study revealed that 49% of Twitter messages were either positive or somewhat positive in their sentiment with regard to emergency preparedness and only 7% were negative or somewhat negative. Statistical analyses revealed a (multimodal) gamma distribution, such that the findings of this study provide support for the use of social media to promote emergency preparedness advocacy in times of crisis. These findings are especially beneficial to public health professionals tasked with disaster preparedness planning, mitigation, response, and recovery.
