Twitter under Storm: Social Media Response Sensitization in the Caribbean
Climate change has led to rising sea levels and warmer sea surface temperatures. These factors contribute greatly to the intensity of hurricanes and floods they provoke. Projections estimate there will be an increase of 45% to 87% in the frequency of Category >4 hurricanes originating in the Atlantic Basin, which typically impact the Caribbean and Continental United States of America. During the 2019 Hurricane Season, there were 20 depressions, 18 storms, 6 hurricanes and 3 major hurricanes. Through this work, we explored the response on Social Media to these natural phenomena as a function of their trajectory, intensity, and previous exposure of the population to intense natural disasters. Data was collected through the Twitter API. The influences of hurricane proximity and intensity on volume of Social Media production was explored. Hurricane Dorian, with its trajectory strongly threatening the previously exposed Puerto Rico, and eventually causing widespread damage in the Abaco Islands of the Bahamas, presented the strongest case for the evaluation of the dichotomy of responses between populations with differences in previous history of exposure. The landscape of historic hurricane exposure Caribbean has radically changed in recent years. Taking advantage of Big Data to help elucidate these dynamics could be instrumental in the tailoring of emergency preparedness plans and the effective design of mental health first aid strategies.
