According to the researchers, every 27.5 million years there is a “big pulse” involving significant geological activity.
In the past five decades, researchers have increasingly expressed the assumption that specific geological events of our planet occur periodically. This could not be proven for a long time, but with the development of technology it became possible to prove that “the heart of the Earth beats” every few million years in the geological sense.

Researchers from New York University and the Carnegie Institution for Science have identified 89 major geological events over the past 260 million years. The investigation has been done In order to discover some order. These events included marine and terrestrial mass extinction events, sea level fluctuations, and tectonic plate shifts.
Using a mathematical method called Fourier analysis, they discovered that the events were clustered at 10 different times over a period of 260 million years.
Michael RampinoThe study’s lead author, their findings suggest that geological events are interconnected rather than random. The next step will be to determine the cause of these cyclical fluctuations. According to experts, plate tectonics and climate change can also play an important role in this regard.
Those who fear that we may see a similar impulse in the coming years need not fear. The last sequence of events occurred about 7 million years ago, meaning that if the theory is correct, Earth’s next big pulse will be 20 million years away.
