Could Earthquakes Cause a Pole Shift?
It has become a common feature when the media reports major earthquakes these days – our planet slowed down and was knocked off its axis. While it sounds dramatic, the numbers are minuscule and make no difference in the greater scheme of things:
NASA geophysicist Richard Gross said that the recent Chilean earthquake “sped up the rotation of the earth enough to shorten the day by an estimated 1.26 millionths of a second”, and moved the Earth’s axis by 8 centimetres. And that the 2004 Sumatra quake, which generated the Boxing Day tsunami, would have shortened every day by 6.8 microseconds, with a 5 or 6 centimetre movement.
And now Japan’s megaquake:
The earthquake moved Honshu 2.4 m (7.9 ft) east and shifted the Earth on its axis by almost 10 cm (3.9 in).
These movements, on their own, a curiosity at best. But what if we have multiple huge quakes at once? I’m thinking perhaps several humongous quakes could set-off a chain-reaction. Could they contribute to movements so large that something else is triggered? Could they be have the energy to trigger a crustal displacement? Could this be the trigger for the Rotational Bending hypothesis of James Bowles?
Now there is no scientific basis for my idea, because as far as I knew, earthquakes that occurred prior to human settlements would not have left any traces. But this could change, I just read this at AstroBio.net:
“Current seismographical data on earthquakes only reaches back a century or so,” says Prof. Marco. “Our new approach investigates wave patterns of heavy sediment that penetrates into the light sediments that lie directly on top of them. This helps us to understand the intensity of earthquakes in bygone eras — it’s a yardstick for measuring the impact factor of earthquakes from the past.”
This method paves the way for discovering ancient clusters of large quakes, perhaps sufficient to have triggered a crustal displacement.
