As per the latest research scientists have successfully recorded the hum of our Earth. Yes, our Earth does make noise. Scientists have long predicted that our Earth is not static or immovable. It also vibrates stretches and compresses and makes noise. The Earth is ringing like a bell the time, says Spahr Webb, a seismologist at Columbia University.

The hum is everywhere, even if an Earthquake occurs or not. As per the study, this for the first time a mysterious noise was recorded beneath the surface of oceanic water. Previously, many quite hums were recorded by various seismic stations but, on the planet’s surface. In 1998, after analyzing data from a gravity meter in east America, a group of Japanese scientists found out that some vibrations or hums were continuous and were never stopping.

Recently, a team of European scientists decided to measure the hums underwater by using ocean-bottom seismometer. They had put 57 seismometers over a four million square kilometer area in the Indian Ocean near Madagascar back in 2012-13. They collected the recorded data from the seismometer substations, and after analyzing those data, they confirmed that the Earth hums continuously. They cleared all other data or noises like ocean currents, tides, waves, glitches, etc. and focused only on him.

The Geophysical Union said in a statement that the researchers were able to reduce the noise level approximately the same level as a quiet land station and when they were done, they were left with the first ever underwater recording of the Earth’s hum. According to the scientists, the hum occurs due to the vibrations that travel with frequencies between 4.5 MHz. This was a much tighter recorded hum range than the first hum that the researchers recorded in the 1990s.

Although the scientists have detected the humming of Earth underwater successfully, they could not figure out what exactly drives this hum. Mostly they believe that the low, steady, continuous and unceasing hum occurs when ocean waves bang on the sea floors continuously all over the earth. Many also suggest that the hum is created due to the acoustic resonance that vibrates our Earth. Still, there is confusion that whether the hum comes from ocean waves or the movement of the atmosphere. So, a more rigorous and in-depth study needs to be done regarding the hum of Earth. Detecting the cause of hum might help us in early prediction of earthquakes or Tsunamis and also it could throw some light on the formation of the earth.
