Alerts (13) are generated at mobile entity devices (12) and servers (16). The alerts are examined at the servers and handled by the server and/or forwarded to a clearing house (22). At the clearing house, emergency events (40) are created in response to the alerts by an event module (36). A notify module (38) compares events to an information need (304) associated with a subscriber profile (46) to determine whether a subscriber associated with the subscriber profile should be notified about events. The notify module also handles interactive search requests from a client (20) for the events.
