This paper presents a qualitative formal framework to model the impact of an event. An event could be a forest fire or a flood, for example, that results in a discernable change such as a reduced vegetation height. This framework provides a qualitative classification of impacts in order to reason about events and their impacts. The underlying conceptual model distinguishes between immediate and delayed impacts. Based on this distinction, a set of basic types of impacts are differentiated, in particular abrupt and gradual impacts. We analyze how the temporal relation between an event and an impact can be used to capture combinations of impact types, called evolving impacts. To link event-impa..
