About Emergency Notifications

The Northwestern University Emergency Notification System disseminates timely information to the campus community in the event of a crisis affecting the University.

Types of Notifications


For immediate or imminent threats, messages titled AlertNU notify members of the Northwestern community via email, text, phone calls, digital screens, the web and social media when there is an emergency occurring on campus that requires immediate action, like an active aggressor.

AlertNU messages will be denoted with the color red, where possible.
