Our planet pulsates every 26 seconds, and scientists have not been able to explain this phenomenon for more than 60 years.
In the early 1960s, geologist Jack Oliver first recorded this phenomenon, which was called "microseism". At that time, Oliver could only detect the fact of pulsation, but he did not have at his disposal the advanced tools that modern seismologists use. Since then, scientists have spent a lot of time observing this phenomenon, and even managed to determine the point of its origin - this is a place in the Gulf of Guinea, which is called Bonnie Bay.
Some scientists believe that the reason for this micropulsation is quite prosaic. Beneath the world's oceans is the continental shelf, which plays the role of a giant breakwater. When waves crash against this particular point on the shelf in the Gulf of Guinea, they generate vibration that can be picked up by instruments.
But other seismologists point out that the source of the pulsation lies suspiciously close to the Sao Tome volcano, which is located just in Bonnie Bay. And it may well be a microseismic generator - such a precedent has already been recorded in Japan. In general, the debate about the origin of the earth's pulse has been going on for a long time, and scientists still have not come to a final opinion. As a rule - and this is true - seismologists are busy with more pressing issues that require their attention, and there is not enough time and resources to solve the microseismic puzzle. To date, this mystery remains unsolved.
