Tweet Diffusion Over Space And Time: A Comparison Of A Winter-Weather And Tornado-Outbreak Case Study, Alyssa Margaret Cannistraci

Social media allows people to receive, engage in, and share weather information. Users of the social media platform Twitter actively share weather content via tweets, which researchers can acquire through an Application Programming Interface (API). APIs return tweet content, as well as temporal and spatial characteristics (latitude and longitude coordinates).

For this work, I compared how tweets spread (“diffuse”) over space and time during two natural hazard events in the United States. The first case study is a winter weather event that The Weather Channel named …
