Abstract (150 Words)

Terror attacks disturb social order, and impact the communications between stakeholders. Responsible organizations seek to learn the rules of public information dissemination, thus better manage the crisis communication during terror attack. Guided by social capital theory, this study took the 2017 NYC marathon attack and Hawaii false missile alarm as examples and examined which sources the public trusts most during varying phases of terror threats. The study also explored the content of the most retweeted crisis communication information, in an aim to facilitate better communications between emergency responders and the public, which would help the organizations actively accumulate social capital in the long term.
