Surviving the Buffalo Blizzard: Online Interactions, Mutual Assistance, and the Power of Weak Ties

In the past, we have written about how the information and communication technologies could expand human dynamics from a pure physical space to a relational and cyber context. One finding we have noticed is the inseparable nature of human dynamics in the physical-digital "phygital" context. 

In a recent publication, with Lucie Laurian, Andrew Crooks and Emmanuel Frimpong Boamah, we explored how online interactions can foster voluntary mutual assistance during the Buffalo blizzard—and how these digital connections can translate into greater resilience in the physical world. The key findings include:

• 🔗 Brokers & weak ties: Online platforms created networks of weak ties that connected otherwise disconnected communities, expanding the flow of information and resources.
• 🤝 Online mutual assistance: Through social media conversations, people requested and offered practical, informational, and emotional support—including assistance that proved critical during the blizzard.
• 🏙️ Digital urban commons: Virtual spaces can function as digital urban commons—like public places in the cybersphere where residents can access, collectively manage, and freely share resources to support crisis response and recovery.

Together, these findings highlight how digital connections can become real-world resources when communities face extreme events, and offer insights for emergency management agencies to partner with grassroots online communities and develop formal–informal mutual aid strategies that can strengthen community preparedness and response in future crises.

Abstract:

In December 2022, Buffalo, New York, experienced a once-in-a-generation blizzard. The four-day lake-effect snow accompanied by storm-force winds knocked down power lines, halted emergency services in several towns and resulted in forty-seven fatalities of residents who lost heat and power or were trapped in the snow. In response to the storm, Buffalonians demonstrated strong solidarity through quickly self-organized Facebook groups to exchange resources and coordinate mutual aid. Our study examines the emergence of grassroots mutual assistance through online–offline interactions and its impact on resilience in the physical world. We manually collected blizzard-related conversations, used machine learning to identify mutual-aid messages, and applied social network analysis to examine users’ interactions. Our findings reveal that Facebook users delivered life-saving assistance through online conversations involving requesting and offering practical, informational, and emotional support. The Facebook blizzard communities developed networks of weak ties that expanded access to vital resources and facilitated the flow of information and materials among disconnected residents. This research highlights virtual spaces as digital urban commons where strangers can benefit from emerging social capital during crises. It also offers insights for emergency management agencies seeking collaborations with grassroots online communities to develop formal–informal mutual aid strategies for future crises.
