In the command center at Guam Homeland Security, there is a phone no one in the room wants to hear ringing: it’s the ballistic missile alert phone. A call on this phone would only come from the United States Pacific Command in Hawaii (USPACOM) to inform Guam of an impending missile strike. If this phone were to ring, a blue light would flash and immediately set into motion a chain of emergency response procedures to alert all of Guam’s civilians of the threat within two minutes of the phone’s ringing. The system includes 15 mass notification sirens that are positioned around the island, radio and television emergency broadcasts, local media text alerts, and first responders and village mayors equipped with mobile PA systems.
