On the night of March 21, 2026, during Indiana University of Pennsylvania's unsanctioned IUPatty's St. Patrick's Day celebration, police say Tymere Johnson, 22, of Clairton, Pennsylvania, fired five shots into the air at 8th and School Street, adjacent to campus, with crowds of student partiers nearby. IUP's Everbridge alert platform pushed two shots-fired notifications (one at 10:14 PM EDT for 8th and School Street, and a second at 11:23 PM EDT for 7th and Locust Street), followed by an 11:56 PM EDT update announcing Johnson's arrest. Police later said they did not believe the second report posed any danger to the community, and no one was injured in either call.

What the threat actually is. A complete warning names the specific danger, such as a shooter, a fire, a tornado, or a gas leak, rather than a vague emergency, because people decide what to do based on what they are facing.
Open to load the 25 reads.
Where the threat is. Saying whether danger is in a specific building, a part of campus, or area-wide lets people judge their own proximity and choose a safe direction. Without a where, a warning is hard to act on precisely.

The protective action to take. A clear, specific instruction, such as shelter in place, evacuate, avoid the area, or run-hide-fight, drives faster and more correct protective behavior than describing the threat alone.

When the message applies. A timestamp, the word now or immediately, or a phrase like until further notice tells the reader whether the danger is current and how quickly to act.

What the hazard could do to the people in its path. Beyond naming the threat, a complete warning conveys its potential consequences or severity, such as that a tornado can level buildings or that a leak could be explosive, so recipients grasp how much danger they are in. Research on warning message content finds that a concrete impact statement helps people personalize their risk and act sooner.
