The authors discuss the use of public social media tools from the emergency management professional\u2019s viewpoint with a particular focus on the use of Twitter. Limited research has investigated Twitter usage in crisis situations from an organizational perspective. This paper contributes to the understanding of organizational innovation, risk communication, and technology adoption by emergency management. An in-depth longitudinal case study of Public Information Officers (PIO) of the Los Angeles Fire Department highlights the importance of the information evangelist within emergency management organizations and details the challenges those organizations face engaging with social media and Twitter. This article provides insights into practices and challenges of new media implementation for crisis and risk management organizations.<\/p>","DOI":"10.4018\/jiscrm.2011100101","type":"journal-article","created":{"date-parts":[[2011,11,16]],"date-time":"2011-11-16T12:54:13Z","timestamp":1321448053000},"page":"1-16","source":"Crossref","is-referenced-by-count":129,"title":["Emergency Management, Twitter, and Social Media Evangelism"],"prefix":"10.4018","volume":"3","author":[{"given":"Mark","family":"Latonero","sequence":"first","affiliation":[{"name":"University of Southern California, USA"}]},{"given":"Irina","family":"Shklovski","sequence":"additional","affiliation":[{"name":"IT University of Copenhagen, Denmark"}]}],"member":"2432","reference":[{"key":"jiscrm.2011100101-0","unstructured":"Bharosa, N., Appelman, J., & de Bruin, P.
