In the Philippines, emergency alerts are broadcast by television and radio stations including GMA and its radio station DZBB, while the Metropolitan Manila Development Authority, known as MMDA, handles traffic and disaster information for Metro Manila. The full alarm system tone associated with those broadcasts has become familiar to many listeners as a signal to pay attention to an official warning. Shared online as a downloadable clip, it is now reused in memes, pranks and edits that imitate a news bulletin, which is why it remains recognisable even outside a real emergency.

The Philippine emergency alert system alarm from GMA and DZBB broadcasts, used for disaster warnings, breaking news edits and prank alerts in videos.
This is the loud, urgent alarm used for emergency broadcasts in the Philippines, built around a piercing siren tone, repeated warning beeps and a formal alert signal that instantly grabs attention. It sounds official and unsettling rather than playful, with a steady, insistent rhythm that makes a listener stop scrolling and check what is happening. In a video it creates instant tension and a sense of breaking news, even before any words appear on screen, because most Filipino viewers recognise it from television and radio alerts for typhoons, earthquakes and other emergencies.
