Geologic activity on Earth appears to follow a 27.5-million-year cycle, giving the planet a 'pulse,' according to a new study published in the journal Geoscience Frontiers.
"Many geologists believe that geological events are random over time. But our study provides statistical evidence for a common cycle, suggesting that these geologic events are correlated and not random," said Michael Rampino, a geologist and professor in New York University's Department of Biology, as well as the study's lead author.
Over the past five decades, researchers have proposed cycles of major geological events—including volcanic activity and mass extinctions on land and sea—ranging from roughly 26 to 36 million years. But early work on these correlations in the geological record was hampered by limitations in the age-dating of geologic events, which prevented scientists from conducting quantitative investigations.
However, there have been significant improvements in radio-isotopic dating techniques and changes in the geologic timescale, leading to new data on the timing of past events. Using the latest age-dating data available, Rampino and his colleagues compiled updated records of major geological events over the last 260 million years and conducted new analyses.
The team analyzed the ages of 89 well-dated major geological events of the last 260 million years. These events include marine and land extinctions, major volcanic outpourings of lava called flood-basalt eruptions, events when oceans were depleted of oxygen, sea-level fluctuations, and changes or reorganization in the Earth's tectonic plates.
They found that these global geologic events are generally clustered at 10 different timepoints over the 260 million years, grouped in peaks or pulses of roughly 27.5 million years apart. The most recent cluster of geological events was approximately 7 million years ago, suggesting that the next pulse of major geological activity is more than 20 million years in the future.
The researchers posit that these pulses may be a function of cycles of activity in the Earth's interior—geophysical processes related to the dynamics of plate tectonics and climate. However, similar cycles in the Earth's orbit in space might also be pacing these events.
"Whatever the origins of these cyclical episodes, our findings support the case for a largely periodic, coordinated, and intermittently catastrophic geologic record, which is a departure from the views held by many geologists," explained Rampino.
Twenty million years?! With all these volcanos popping off right now I thought they were going to say we were in the middle of one of these pulses right now, lol. Oh, ye little men of little minds, ye know not of what I can do. (Don't know who said it, but he should have!:-))
Of course, the mayhem that will take place in 20m years will have been caused by global warming. We know this for a fact. The science is settled.
Those major extinction events were probably because of a giant field of giant space rocks. The Earth is moving along with the Milky Way Galaxy in a circular pattern. Part of that pattern involves traveling through an ORT Cloud. The ORT Cloud is the giant field of giant boulders. A space rock say 5 miles wide smashes into the Earth and there could be lots of damage. Maybe next time there will be rockets to blast the space rocks into dust so the Earth will be saved.
That is about the same as the time for the solar system for each pass through the galactic plane. The time for a complete oscillation from one side of the galactic plane to the other side and back is about 60 million years which makes about 30 million years for each pass through the denser galactic plane.
Interesting reading, thanks for posting.
The meteor that hit the earth at what is now the Yucatan Peninswas and wiped out the dinosaurs 65 million years ago was six miles wide.
If they had only stopped using fossil fuels 27.5 million years ago it would not be hot in June!
Damn you Fred Flinstone!
Pain killer meds, anesthesia for surgery, vaccines, prescription meds etc are less than 200 years old in earth’s age of 5,000,000,000 years.
Humans will become extinct in less than a 500,000 years based on how popular cocaine, heroin, booze, ganja etc is now. We are living in the golden age of human civilization. Enjoy it!
Looks more like it correlates to the Precession of the planet.
There have been a couple of attempts to explain this:
*The Nemesis Hypothesis - that there is a small star or large planet that orbits the sun and once every 27 million years comes close enough to our neighborhood to toss large rocks at us
*The Shiva Hypothesis - Every 27 million years the solar system passes through the plane of the galaxy. This causes gravitational disruptions that send asteroids our way.
Precession is about 26,000 years.
Yeah, I can see that right on the mark at 27.5 million years give or take a day.
What bull this is.

226 million years for one turn around the galaxy so about 8.2 events per tour. IF the pulse is a known, and our speed is also given as a known, then calculate the star charts forward to discover what quadrant of our galactic tour the event will occur in, down to the season and month. Not that there’s any guarantee our galactic speed or the speed of our sun, is a constant.
Planet Earth going thru the galactic plane.
Maybe just a ship thru the rings.

>>If they had only stopped using fossil fuels 27.5 million years ago then we would all be freezing to death in more ice ages occurring.<<
That is the beauty of the term “climate change.” It gets hotter = CLIMATE CHANGE! It gets colder = CLIMATE CHANGE!
It never stays the same so they are always right!
