Earth experiences seismic activities every single day but with the rotation of our planet slowing down the amount and severity of seismic activity will probably change.
The change in the speed of Earth’s rotation could trigger severe seismic activities that might result in large-scale earthquakes, with the focus on densely populated tropical regions.
Now, we might not be able to notice the slight variations in Earth’s speed of rotation, but we are bound to feel its effects in the number of earthquakes.
Forbes Geophysicists have been monitoring the Earth’s rotation speed and they strongly believe that the slow down is closely linked to what’s called a ‘cyclical increase in earthquakes’.
Every earthquake since 1900s was analyzed
The study conducted by the Forbes Geophysicists analyzed every single earthquake that has taken place since the 1900s. They have taken into consideration all earthquakes that reached a magnitude of 7.0 or above, on the Richter scale.
The team was looking for an ‘occurrence of large earthquakes’ and they discovered that every 32 years the number of earthquakes spikes significantly across the globe.
Just like every other team, they wanted to find out why this happens in a pattern, so they compared their findings with a number of ‘global historical datasets’.
There’s a significant link in the increase of earthquakes with the slowing down of Earth’s rotation
Another detailed analysis showed that every 25-30 years Earth’s rotation starts to slow down and the decrease in speed foreshadows an increase in the number in earthquakes.
History shows that the rotation slows down for 5 years before the severe seismic activity begins. So, what does this have to do with the year we’re in?
As a matter of fact, we’re currently in the fourth consecutive year in which the Earth’s rotation has slowed down significantly.
2018 is the last year of the rotation slow down
This (literally) means that we should brace ourselves for some extremely devastating seismic activity.
However, the end of the 5-year slowdown cycle doesn’t necessarily mean it will trigger the destructive seismic activities – this is why some geologists provided reasonable hypothese.
The Earth’s core can stick to the mantle, resulting in a ‘disruption’ to its flow
The ‘disruption’ alters the Earth’s magnetic field and produces a temporary ‘stutter’ in the rotation of Earth. Also, this doesn’t mean that you should start building your earthquake-proof shelter.
The data only point to a ‘striking correlation’ and there is no concrete proof that it will lead to an increase in earthquakes.
Final predictions point towards a potential increase in seismic activity in 2018
The increase could potentially lead to earthquakes strong as 7.0 or greater on the Richter scale. Nevertheless, earthquakes are one of the most unpredictable natural disasters, so there’s no telling how the 5-year slowdown cycle will end.
The same finding also gives scientists a chance to prepare better for what’s coming. All we can do in the meantime is hope they’re finding are wrong.
