In an illustrative embodiment, systems and methods for determining exposure include detecting, based on received data from external entities, an occurrence of a catastrophic event. Responsive to detecting the occurrence, a first matrix is generated indicating features of one or more properties within a vicinity of the catastrophic event, and a second matrix is generated representing characteristics of the catastrophic event. Using the first matrix and the second matrix, a convolution calculation matrix is calculated indicating amounts of correspondence between the first matrix and the second matrix. In real time, in response to detecting the occurrence of the catastrophic event, present risk exposure information to at least one remote computing system associated with at least one property of the plurality of properties, where the risk exposure data relates to the amount of correspondence between the first matrix and the second matrix in reference to the at least one property.
