My aim in this paper is to explore the idea of human moral responsibility for (the outcomes) of natural disasters. First, I discuss the claim that there is often a human causal contribution to negative outcomes of even such paradigmatic natural disasters as earthquakes, typhoons, and volcano eruptions. Second, I attempt to move away from discussions attributing human causal responsibility to discussions attributing human moral responsibility for such outcomes (and to the obstacles to such attributions). I suggest that in most (...) (perhaps even all) cases of moral responsibility for the outcomes of natural disasters moral responsibility is grounded in culpable negligence, including culpable failure to prevent the side-effects of our actions or omissions.
