According to scientists, major geological events, such as mass extinctions and volcanic eruptions, repeat every 27 million years. They call it “Earth Pulse” in a new study.
Geologist Michael Rampino, lead author of the study, believes that there is no pattern in geological events over time.

“But our study provides statistical evidence for common cycles, which suggests that these geological events are correlated rather than random,” Rampino said. new version from New York University where he was a professor. That a lesson Posted in Geoscience Frontiers on June 17th.
Scientists have collected data over the last 260 million years and analyzed 89 major geological events to look for patterns. This is a group event Extinction of species living on land and oceans, massive volcanic eruptions, depletion of oxygen from the oceans, large fluctuations in sea level, large movements and reorganization of the earth’s tectonic plates.

When the researchers collected data and performed statistical analysis, they found that these events formed clusters at 10 different time points.
They further show that events peak every 27.5 million years. The analysis also revealed that the last peak occurred about seven million years ago and there were another 20 million years before major geological changes on the planet.
