jats:p This Progress Report reviews the geographical literature concerning environmental hazards and risk focussing particularly on areas that require and enhance interdisciplinary working between human and physical geographers. Although there are still substantial gaps between disciplinary siloes, there is a growing recognition that critical interdisciplinary work is vital. Key areas include early warning, urban planning, hazard and risk mapping, scientific advisory processes, risk communication and institutional geographies. We review some of this work, examine emerging theory and consider the opportunities for greater knowledge exchange between disciplines using critical physical geography and cognate approaches. </jats:p>
