Quantifying people’s experience during flood events with implications for hazard risk communication
Fig 4
Jaccard distance between scenes tagged with positive (‘nature’, ‘landscape’) and risk-signalling (‘flood’) words posted before and after flood events 2004-2014.
These results illustrate that before risk communication the dissimilarity increases evenly between ‘flood’-tagged and positively-tagged scenes with the increase of the event severity. After risk communication it also evenly decreases with event severity. This can be indicative of the fact that the perceived event severity affects segregation of the visual material in the same manner as authoritative risk communication, where the former segregates crowds according to the perceived danger, whilst the latter re-focuses their attention back onto familiar landscapes.
