Risk awareness and preparedness attitude are important elements to disseminate flood disaster preventive measures in a community. This study examines how social networks influence individuals’ risk awareness and preparedness values. This study is based on the filed survey conducted in flood prone micro-hot slum areas in Mumbai. Results show cohesive groups play important role in shaping individuals’ risk perception and preparedness intention. In other words, individuals share similar risk perception and preparedness values with whom they closely interact in day to day. The role of structurally equivalence group is negligible as found in the study. We did not find any impact of socio-demographic characteristics on individuals’ attitude formation.
