Even though we know a lot about the Earth, and are learning more and more each day, there is still a lot to learn. Here are just 4 really bizarre and somewhat terrifying sounds that occur on the Earth.

These sounds happen under the ocean, on land, and in the sky.

Some of them are even heard by millions of people.

The Bloop

The U.S. National Oceanic and Atmospheric Administration recorded a mysterious sound deep in the Pacific Ocean in 1997. The sound has been nicknamed the Bloop, and its origins have been debated ever science it was heard.


There have been reports around the globe from people reporting and recording “strange sounds” known as skyquakes. The video above is a bit long, but you only have to listen to a minute to get the idea. Whatever is causing the noise, I hope I never get close enough to see it.


This was recorded by the National Oceanic and Atmospheric Administration (NOAA) in 1991. This is the sound at 1X speed. It can still be heard today throughout the Pacific Ocean. Since it was discovered, the sound has been gradually declining in volume, but that doesn’t make it any less freaky.

The Hum

Since the 1970s, there has been a steady flow of people around the world complaining about a low persistent hum that no one else can hear. What makes it so weird is that it has been medically proven to be a real phenomenon.
