Southern Illinois University Carbondale has selected a network of locations and personnel on campus to receive SIU Alerts from the Department of Public Safety (DPS) and in turn, notify the occupants of their building of the emergency.

SIU Alerts are messages about an emergency. The message may alert you to an emergency situation, ask you to take action, or both. Some weather warnings including flash flood, severe thunderstorm, winter storm, and tornado warnings will also be sent as an SIU Alert. The messages are short (only 160 characters long). For more detailed information, you may need to go to another source of University emergency information.

These messages are communicated through a radio notification system that can reach the Southern Illinois Airport, the SIU Carterville campus, and Touch of Nature. Over 200 scanners were provided to campus personnel for the network.

You can listen to the SIU emergency broadcasts on 453.800 MHz.

Please note that no communication distribution method, including the radio network, is infallible. For that reason, SIU uses redundant systems of emergency communication, including telephone, web, e-mail, text messaging, and person-to person, to distribute news and instructions during an emergency. Before an emergency arrives, please make yourself aware of all of the distribution methods by visiting our Emergency Communications website at
