Fig. 3: Geography of earthquake intensity and embeddedness structure.

From: Triadic embeddedness structure in family networks predicts mobile communication response to a sudden natural disaster

A Earthquake intensity at each geographic locale (town/village level). B Change in structure of embeddedness before vs. after the earthquake at each locale: count of number of pairs of embedded nodes (i.e., embedded edges or links) in families after the earthquake is stable and similar to before the earthquake. C Embeddedness structure 1–4 weeks before the earthquake at each locale (average number of family dyads that share a nonfamily friend). D Average ratio of reciprocated calls across locales 2–5 weeks after the earthquake. Intensity is not significantly correlated with embeddedness, Pearson’s r = −0.128, p = 0.138, or reciprocity, r = −0.106, p = 0.222; embeddedness and reciprocity are significantly correlated, r = 0.505, p < 0.0001. Overall, embeddedness structure is stable to the earthquake’s shock and is correlated with post-earthquake reciprocity behavior.
