Social media plays a crucial role in crisis events, facilitating information sharing and post-disaster rescue efforts. Research indicates that bonding, bridging, and linking social capital can enhance community resilience. Social media platforms may serve as vital resources for individuals and communities in the aftermath of disasters.
Social media is changing the narrative during crisis events. It has facilitated citizen-led emergency dispatch and rescue, information sharing and communication between loved ones in the moments before, during and after a disaster. Researchers of social capital have found that bonding, bridging, and linking social capital can lead to resilient outcomes. With increased use of social media on a day-to-day basis and during a crisis, we still know little about the association between social capital and online social media use. Controlling for demographic characteristics and earthquake intensity, I investigate the association bonding, bridging and linking social capital and hyperlocal social media use following the earthquake and its aftershocks. Using a quantitative cross-sectional longitudinal study across 121 Nextdoor online neighborhoods in California's Napa Valley region across 42 days in August and September of 2014 (N = 3570), I find that bridging and linking social capital led to more online communication via Nextdoor. This finding comes with an important implication, namely, that social media can serve as a primary source of recourse for individuals and communities following a disaster. Social media platforms provide a conduit for accessing and activating bridging and linking ties that can expedite collective action in a time of need. Communities should consider policies that increase levels of social capital, well as social media platforms that can activate social ties when they are needed most.
