A versatile Citizen Alert System is connected to Internet and private databases to acquire real time information useful for subscribed users. During registration, users are required to provide multimedia contact information, including telephone numbers, cell phone numbers, pager information, Blackberry or PDA information, e-mail address, and physical address, along with user defined sensitivities to alerts, including sensitivities to natural emergencies, man made emergencies and professional requirements. The system has a local or remote administrator that constantly analyzes the acquired data in accordance with requirements of each and every user, orders the data to generate alert information specific to a user, and communicates the alert to each and every user using multiple delivery platforms. A user specific, secured web page providing details of alert and hyperlinks constitutes an additional information source.
