How frequently are Emergency Alert announcements repeated?

Emergency Alert announcements are repeated every 15 minutes as part of standard emergency communication protocols. This frequency ensures that crucial information regarding emergencies reaches the public consistently without overwhelming them with constant alerts. The 15-minute interval strikes a balance between providing timely updates for ongoing situations and allowing people to absorb and act on the information provided.

For instance, if an emergency situation is evolving, repetition at this interval allows residents to stay informed about the latest developments and actions they should take. The choice of this timeframe is also practical, as it maximizes outreach while minimizing the risk of people becoming desensitized to alerts due to frequent interruptions. Therefore, the correct answer reflects established emergency management practices that prioritize both information dissemination and public responsiveness.
