This strange buzz has gone around the world but no one has heard

This strange buzz surrounded the whole world. But no one heard him.

A seismic recording device installed in Mayotte was the first to detect the buzz, but not the first to have been noticed.

There was a buzz that no one could hear. It was a seismic event, caused on 11 November off the coast of Mayotte, a small island located between Madagascar and Mozambique.

From there, he toured the world, though it was quite unusual (not very seismic) for almost no one to notice, as Maya Wei-Haas reported for National Geographic. Some people, however, paid attention, triggering a quest for the source of the buzz, which she says has not been solved yet.

According to National Geographic, the buzz was strange for several reasons. First, it rang at a single ultra-low frequency, like a well-tuned bell. Seismic waves usually involve many different frequencies. Second, the wave emerged and circled the planet without the usual signs of an earthquake; No one in the area was shaking, and the "p waves" and "s waves" associated with the buzz, the kind of waves that you actually feel during an earthquake, were so weak that they did not feel like it. they were almost undetectable. However, a report from the French government dated November 12 revealed that Mayotte had slipped 6 centimeters to the east and 3 centimeters to the south. [The 10 Biggest Earthquakes in History]

Scientists have offered a number of explanations for this strange seismic event near Mayotte, reported Wei-Haas. But none is yet confirmed. Perhaps a "slow earthquake" hit the region, the kind that does not cause much intense tremor because it occurs over a much longer period. Perhaps a bubble of magma has slipped beneath the surface, or has it slipped into a large hole in the crust so as to interact with the local geology to produce the resonant sound. The researchers even speculated on a meteor strike, although this seems unlikely. For the moment, the exact cause remains a mystery.
