1. A method comprising: receiving a message that defines an initial target area for distribution of an alert; identifying, from a plurality of wireless coverage areas of a wireless carrier network, a first set of one or more coverage areas that are each only partially encompassed within the initial target area and a second set of one or more coverage areas that are each fully encompassed within the initial target area; for each coverage area in the first set of one or more coverage areas, defining a respective target area that is less geometrically complex than the initial target area by defining an overlapping area between the initial target area and the coverage area and designating as the respective target area an approximation of the defined overlapping area; in each coverage area in the first set of one or more coverage areas, broadcasting the alert in a first manner that directs a recipient device to output the alert only if a location of the device is encompassed within the respective target area defined for the coverage area, wherein broadcasting the alert in the first manner comprises broadcasting the alert with a flag that directs a recipient device to determine whether a location of the device is within the respective target area defined for the coverage area; and in each coverage area in the second set of one or more coverage areas, broadcasting the alert in a second manner that directs a recipient device to output the alert regardless of a location of the device, wherein broadcasting the alert in the second manner comprises broadcasting the alert without the flag.
