Abstract: An emergency alert system that facilitates communication with groups and/or individuals (e.g., residents, tenants, inmates, passengers, students, teachers, employees, public officials, service members, hospitality guests, patients, and event spectators) in a pre-definable area such as a geographic area, a contained structure, and a geo-fence area via each individual's mobile communication device while in communication with a communication network, the system including a non-transitory, machine-readable medium storing information that includes machine-readable, processor-executable instructions and a data processor that executes the instructions stored in the non-transitory, machine-readable medium. In some implementations, the data processor is adapted to account for each individual within the pre-definable area during a period of time, identify any individual not within the pre-definable area during the period of time, and aggregate and compile individual location and accountability data.
