Abstract Disaster clusters refer to major disasters that cluster in space and time without any linkage, resulting large direct damage economic ripple effects (EREs). However, the cumulative EREs caused by a disaster may not be equal summation of individual within cluster. We constructed global input-output model suitable for analysis demonstrated extent this difference with example two typical catastrophes occurred 2011 (the Great East Japan Earthquake Thailand Flood), an interval only 136 days. The results indicate that: (1) suffered 11 35 countries affected (30%) are “1 + 1 > 2”, < 2” 24 (70%). This indicates there is significant between losses. related factors such as trade distance, influence disaster-affected sectors, ties; (2) more than times loss have industrial dependence, mostly aggregated key sectors strong fast chain; (3) Additional due extension recovery period will close ties country, further magnifying difference.
