Disasters threaten mankind and degrade our survival conditionsand have a serious impact on human society. Several previous disaster spreading models in complex networks are reviewed. Based on the evaluation of their advantages and disadvantagesa more realistic model in the networks with redundant systems is proposed. For different models in different network structuresthe differences of spreading processes and the effects of some important parameters are analyzed by means of simulation. The disaster processes in the networks with redundant system become slowwhich permits of longer rescue time to repair the system. It can explain the reason why large-scale disaster events rarely happen in real life.
