“…The data supports this assumption, even in an environment with scarce Internet access. For those with higher levels of education it is possible Internet sources fulfilled the complementary "interpersonal networking" functions described by Perry (2007). However, given the limited access to the Internet before and after the earthquake, it is not clear whether the Internet had sufficiently diffused through Haitian society so as to provide a complementary function for those who used the technology, or if the Internet simply served to reinforce information acquired through sources like newspapers.…”

“…The information needs of earthquake survivors are thus likely to be multifaceted, and the communication of information through media to meet those needs is a crucial part of responding to earthquakes. Indeed, literature has demonstrated the critical role media play in the aftermath of disasters (e.g., Littlefield & Quenette, 2007;Perry, 2007;Procopio & Procopio, 2007). So-called old and new technologies may play a role in meeting challenges created by disasters (Gunawardene & Noronha, 2007).…”

“…Nevertheless some inferences from the data can be drawn to provide implications for practice and future research. Perry (2007) noted that mediated sources are often complemented by interpersonal networks to complete information diffusion and reduce uncertainty. This observation is evident in the traditional repertoire adopted by most Haitians.…”

“…A considerable body of literature has investigated which sources individuals turn to for information following crises (e.g., Austin, Liu, & Jin, 2012;Liu, Austin, & Jin, 2011;Perry, 2007;Procopio & Procopio, 2007;Spence, Lachlan, & Burke, 2008. However, such research has typically considered why or how each medium is used in isolation, compared usage levels of media by different demographic or cognitive factors, and/or compared the efficacy or credibility of several mediums.…”

Disasters and Information Source Repertoires: Information Seeking and Information Sufficiency in Postearthquake Haiti

This study examines how Haitians used "information source repertoires" to meet information insufficiencies following the 2010 earthquake. Using survey data gained in Haiti, the study explores which demographic and structural factors predicted the number of sources used and combinations of information sources following the disaster. Analysis of the data revealed two distinct repertoires of information sources: a "traditional" repertoire of radio, TV, church, and word of mouth; and an "elite" repertoire of newspapers, the Internet, short-message-service, billboards, and the national police. Results of hierarchical multiple regression analyses showed that demographic variables like education were stronger predictors of information repertoires than conditions like living in a refugee camp or having one's home destroyed. Results also suggested that greater reliance on a traditional repertoire led to decreased information sufficiency. Contrary to previous crisis research, men were found to be more active information seekers than women, suggesting that scholarly knowledge about information seeking and media use after crises in developing nations is limited. Implications for practice are directed at international development and aid organizations in planning postdisaster information provision efforts. earthquake in Haiti was the second-deadliest in the recorded history of the planet. The 7.0 magnitude quake shattered Haiti's already deficient infrastructure, leveled Erich J. Sommerfeldt, Ph.D., is an Assistant Professor in the Department of Communication at the University of Maryland. His research focuses on activism and the role of strategic communication in civil society.

“…A study that evaluated the dissemination of tsunami warnings in Mauritius (Perry, 2007) found that both television and radio were equally effective in disseminating the initial tsunami warning and that television became more important later. The impact of an interpersonal warning system was minimal, though, and media messages did not provide sufficient and accurate enough information about the disaster.…”

Facilitating disaster preparedness through local radio broadcasting

The 2008 Disaster Mitigation Preparedness (DMP) study took place in Aceh province, Indonesia. It sought to help develop radio programmes and messages to increase resilience to disasters. The role of radio was evaluated during and after the 2004 Asian tsunami disaster. The study team interviewed 984 tsunami survivors from nine sub-districts of Banda Aceh, and local nongovernmental organisations convened eight focus groups around the area of Aceh Besar. Six key informant interviews were held with government disaster management agencies. The DMP survey is the first of its kind to interview a representative random sample of Banda Aceh residents. It reveals the importance of community and social networks, during disaster situations, when essential communications are down. A disaster warning information system based on a multi-media approach needs to be developed. The wider community should be involved in the planning, education and training of Banda Aceh and Aceh Besar residents to facilitate appropriate personal and community survival strategies.

Estimating the growth models of news stories on disasters

Understanding the growth models of news stories on disasters is a key issue for efficient disaster management. This article proposes a method to identify three growth models: the Damped Exponential Model, the Normal Model, and the Fluctuating Model. This method is proven to be valid using the 112 disasters occurring between 2003 and 2008. The factors that influence the likelihood of the growth models include disaster types, newsworthy material, disaster severity, and economic development of the affected area. This article suggests that disaster decision-makers can identify the respective likelihood of the three growth models of news stories when a disaster happens, and thereby implement effective measures in response to the disaster situation. IntroductionDisasters can be defined as acute, collectively experienced traumatic events with a sudden onset, and they can be both natural (e.g., hurricanes, floods, earthquakes) and man-made (e.g., plane crashes, industrial accidents, terrorist attacks) (Norris, Friedman, & Watson, 2002). Meeting the information needs of the public and providing timely support are vital in disaster situations (Keselman, Slaughter, & Vimla, 2005). When a disaster hits an entire community or nation, most people experience the event largely through mass media (Rasinski, Berktold, Smith, & Albertson, 2002). In a world of severe competition, media organizations are also interested in boosting popularity ratings, and so may favor shocking or sensational information (Nacos, 2005). Despite the mass media's role as the most frequent source of information for the public to learn about disasters, the mass media are required to make choices about what they will share and emphasize in order to satisfy the public's demand for information about a disaster (Seeger, Sellnow, & Ulmer, 2003). In some instances, some information from mass media can arouse negative effects. Studies show that the number of news stories on a disaster directly affects audience response (CDC, 2002). The effects of news coverage of disasters on children can be especially troubling because the context of the disaster may not be understood clearly.The effective communication of disaster information is an important consideration for the mass media. Studies show that disaster coverage comprises a number of stages (Fink, 1986;Pauchant & Mitroff, 1992). According to the life-cycle perspective, the number of daily news stories about a disaster will increase until it reaches a vertex, then decrease (Rogers, Dearing, & Chang, 1991;Thelwall & Hellsten, 2006). This perspective is proved by some typical disasters, such as epidemic diseases and hurricanes (Shih, Wijaya, & Brossard, 2008). But do various disasters have a similar news coverage model? If not, what determines the coverage models? These questions have not been solved by quantitative methods yet.With the rapid development of society and the economy in China, natural or human caused disasters happen more and more frequently. Every day the public is exposed to a large volume of disast...
