Average survival rates after 50 years for networked nodes as a function of the correlation strength among disasters.

<p>Solid lines describe networks that are very inhomogeneous (<i>β</i> = 0.8), dashed lines describe networks that are more homogeneous (<i>β</i> = 0.2). Red curves describe spatial correlations among disasters, black curves represent spatial-temporal correlations and blue curves represent temporal correlations.
