Apocalyptic fears were sparked among people in Chile as a strange trumpet-like noise was heard for two minutes, frightening animals and people. Dogs were barking in fear and the atmosphere was eerie, as the loud, unknown sound went on during the night.
Under the video the uploader wrote verses of the Bible: Matthew 24:31 reads: “And he shall send his angels with a great sound of a trumpet, and they shall gather together his elect from the four winds, from one end of heaven to the other.”
However, some social media users were not so convinced that the sounds were from the heavens, suggesting rather that the noise could have come from a steel industry somewhere nearby.
“Honestly this sounds like a shipyard, construction or mining sounds,” one user wrote.
Another added: “Could be a train car with faulty brakes.”
Similar sounds were heard around the world, but their ultimate cause remains unknown. Possible theories include:
Tectonic plates grinding – Tectonic plates are pieces of the Earth’s crust and uppermost mantle, together referred to as the lithosphere. The plates are around 100 km (62 mi) thick and consist of two principal types of material: oceanic crust (also called sima from silicon and magnesium) and continental crust (sial from silicon and aluminium).
Atmospheric pressure – Atmospheric pressure is defined as the force per unit area exerted against a surface by the weight of the air above that surface.
Trains shunting – Self explanatory – noise comes from trains in reaction to the track and overhead wires.
Construction – Building works, especially if going on at the same time across a specific area, can led to similar sounds.
Aliens – Can this be an alien lifeform in the sky, perhaps scouring out Earth?
HAARP weapon – Rumours persist that the U.S. government uses secret weapons in the sky for defence and weather modifying, the High Frequency Active Auroral Research Program (HAARP). This wouldn’t explain the sounds in other countries however…
The Apocalypse and the Seven Trumpets of Heaven – Seven trumpets are sounded, one at a time, to cue apocalyptic events that were seen in the vision of the Revelation of Christ Jesus, by John of Patmos. Somewhat more worrying as it would signal the end of the world…
