Earth beats 27.5 million years

Jakarta, CNN Indonesia —

Geologists Earth found the Earth ticking in a span of 27.5 million years or more. It determines the geological activity of the Earth.

According to a new study published in the journal Geoscience Frontiers, over the last 260 million years dozens of major geological events ranging from sea level changes to volcanic eruptions appear to follow this rhythmic pattern.

The team has scoured the literature and found 89 major geological events that occurred in the last 260 million years citing Futurism, Thursday (24/6).

“Many geologists believe that geological events occur randomly over time,” said Michael Rampino, a geologist and professor at New York University.

Major geological events in question include sea level fluctuations, ocean anoxic events (when the oceans are toxic due to oxygen depletion), major volcanic activity and changes in Earth’s tectonic plates. Experts have researched it using a computational tool known as Fourier analysis to pick up spikes in the frequency of events.

They found that most of the events were grouped into 10 separate times, which averaged 27.5 million years apart. That figure is “probably” imprecise, but it makes a pretty good estimate with a 96 percent confidence interval.

Apart from this the researchers only looked at the phenomena of the last 260 million years when natural phenomena on Earth were quite accurate. But they think the results may extend further back in planet Earth’s history. But judging by the sea level change data back about 600 million years, it seems that there is a ticking on this scale.

It is not clear what causes the earth to beat like that in geological activity, but it could be because it is pushed internally by plate tectonics and movements in the earth’s mantle.

Quoted Live Science, the researchers suspect has something to do with the movement of the Earth, solar system and galaxies.

For example, the earth’s pulse at 27.5 million years is close to a 32 million year vertical oscillation around the galactic center

Rampino and his team hope to get better data on the dating of certain geological events. They also plan to analyze a longer period of time to see if the pulse extends far back in time.

The researchers hope that, one day, they will be able to get precise figures on the astronomical movement of the Earth through the solar system and the Milky Way. They could see if there was a correlation between astronomical and geological cycles.

Rampino explained that if such a pattern existed, the last cluster was around 7 million to 10 million years ago, so the next one would likely come in 10 million to 15 million years.
