Many real world complex systems such as infrastructure, communication and transportation networks are embedded in space, where entities of one system may depend on other systems. These subject to geographically localized failures due malicious attacks or natural disasters. Here we study the resilience a composed two interdependent spatially geographical attacks. We find that if an attack is larger than finite (zero fraction system) critical size, it will spread through entire lead its complete collapse. If below remain localized. In contrast, under random needs be removed initiate present both numerical simulations theoretical approach analyze predict effect local size. Our results demonstrate high risk infrastructures can useful for designing more resilient
