Overview

Randomized trial integrates social media sentiment with hazard data to assess community resilience after earthquakes, suggesting improved disaster responses.

Key Points

This research aims to evaluate how social media sentiment can enhance disaster resilience assessments after earthquakes.
Integrated social media sentiment with hazard data, damage assessments, and vulnerability indices.
Analyzed data from the Ridgecrest earthquake sequence of July 2019, examining temporal and spatial community responses.
Correlated sentiment data with objective measures like peak ground acceleration and subjective reports.
Found a decline in positive sentiment and a rise in negative sentiment during the earthquake events.
Established weak correlations between sentiment and objective hazard measurements (peak ground acceleration).
Demonstrated stronger alignment of sentiment with subjective 'Did You Feel It?' reports, suggesting improved hazard perception.
