As social media grows more popular, an increasing number of people are using social media platforms to obtain and share information about approaching threats and discuss their interpretations of the threat and their protective decisions. This work aims to improve understanding of natural disasters through social media and provide an annotation scheme to identify themes in user’s social media behavior and facilitate efforts in supervised machine learning. To that end, this work has three contributions: (1) the creation of an annotation scheme to consistently identify hazard-related themes in Twitter, (2) an overview of agreement rates and difficulties in identifying annotation categories, and (3) a public release of both the dataset and guidelines developed from this scheme.

Research paper thumbnail of Achieving Accuracy through Ambiguity: the Interactivity of Risk Communication in Severe Weather Events

For hurricane risk communication, visual information products—graphics—generated by meteorologists and scientists at weather agencies portray forecasts and atmospheric conditions and are offered to parsimoniously convey predictions of severe storms. This research considers risk interactivity by examining a particular hurricane graphic which has shown in previous research to have a distinctive diffusion signature: the ‘spaghetti plot’, which contains multiple discrete lines depicting a storm’s possible path. We first analyzed a large dataset of microblog interactions around spaghetti plots between members of the public and authoritative weather sources within the US during the 2017 Atlantic hurricane season. We then conducted interviews with a sample of the weather authorities after preliminary findings sketched the role that experts have in such communications. Findings describe h...

Research paper thumbnail of “Sometimes da #beachlife ain't always da wave”: Understanding People’s Evolving Hurricane Risk Communication, Risk Assessments, and Responses Using Twitter Narratives

It uses social media data, which offer unique records of what people convey about their real-world risk contexts. Twitter narratives from 53 people who were in a mandatory evacuation zone in a New York City neighborhood during Hurricane Sandy in 2012 were qualitatively analyzed. The study provides rich insight into the complex, dynamic information behaviors and risk assessments of people at risk, and it illustrates how social media data can be collected, sampled, and analyzed to help provide this understanding. Results show that this sample of people at significant risk attended to forecast information and evacuation orders as well as multiple types of social and environmental cues. Although many tweeted explicitly about the mandatory evacuation order, forecast information was usually referenced only implicitly. Social and environmental cues grew more important as the...

Where popular articles once lamented the public impropriety of mobile telephony and its role in hastening life’s already fast pace, we instead heard accounts of calls from frightened passengers on hijacked airliners and doomed office workers in the World Trade Center towers and Pentagon to parents, spouses, and friends. But knowledge of the comforting receipt of those final “I love yous” and the hope that came with apparent calls from the rubble of the buildings must be reconciled with the sad awareness that the same technology had also helped the terrorists communicate and coordinate their efforts. These accounts of the extremes of the use of mobile telephony are now part of the public consciousness; as a result, I expect the divide between the attitudes of users and nonusers to narrow. While everyday struggles to define and adhere to social norms, or socially accepted behavioral...

Moreover, the adaptive practices of these broadly dispersed groups are still not well understood. We ask:How do globally distributed teams temporally coordinate to accomplish their work? We examine an extreme case of online temporal coordination: high-tempo information curation about the urgent humanitarian crisis following the 2017 Hurricane Maria landfall in Puerto Rico. Our analysis of synchronous chat transcripts and data artifacts produced by The Standby Task Force reveals how this digital humanitarian group establishes temporal coordination through different shared understandings of time relative to the crisis, the globally distributed work, and the collaborative information technologies. We make four c...

More recently, crisis informatics has developed an analysis of these phenomena from social and computational perspectives. To further to assess the consequences and opportunities of technological developments in the field, we re-interpret the concept of informating, first developed by Zuboff to describe the impacts of technological changes on the workplace during the 1980s. We draw on four contemporary examples of how ICT is changing the way we conceive of and respond to natural hazards to offer a new reading of the concept of informating in the growing field of crisis informatics. We then argue that this concept suggests the adoption of a more critical agenda for crisis informatics research to better respond to contemporary challenges presented by climate change and natural hazards.

Social media supports “backchannel ” communications, allowing for wide-scale interaction that can be collectively resourceful, self-policing, and generative of information that is otherwise hard to obtain. Results from our study of information practices by members of the public during the October 2007 Southern California Wildfires suggest that community information resources and other backchannel communications activity enabled by social media are gaining prominence in the disaster arena, despite concern by officials about the legitimacy of information shared through such means. We argue that these emergent uses of social media are pre-cursors of broader future changes to the institutional and organizational arrangements of disaster response.
