lithospheric overshoot, a process whereby the equatorial lithosphere sluggishly overrides the decelerating underlying mantle
If the rotation is slowing down shouldn't there be less earthquakes...
This is just a wild guess, do TPTB want us to pay too put up more windmills to compensate for this man-made lithospheric overshoot...

Another story from the libs,funny how scientists can predict an earthquake,yet they can predict something that has never happened,sounds like another Al Gore story,global warming BS
We envisage the weak forces responsible for clustering originate from lithospheric strain induced by seismicity itself, by finite strains over
teleseismic distances, or by other sources of lithospheric loading such as Earth’s variable rotation. For example, quasi-periodic maxima in rotational deceleration are accompanied by increased global seismicity at multidecadal intervals.
Maybe they're right. Now what?

From the paper:

So various, but weak, forces on the lithosphere (including changes in the Earth's rotation), lead to earthquake clusters. Makes sense. They use a lot of statistical stuff to find correlations. Maybe they're right. Now what?

For example, I would like to know the specific periods of rotational slowing they refer to. They seem to imply they have found more of these periods than previously known and published by eg Sidorenkov in 2009.
They are saying they KNOW there are previous slowings of 5 years in milliseconds! HOW can you find such information in the history of the planet, surely not in the rock record or any other.
The daily version of the COMB2000 observed length-of-day series [Gross, 2001a] is used in this study. This series is derived from a combination of Universal Time measurements taken by the techniques of optical astrometry, lunar and satellite laser ranging, and very long baseline interferometry. Besides estimating Universal Time, the Kalman filter used to combine the measurements also estimates its time rate-of-change and hence the length-of-day [Gross et al., 1998]. The COMB2000 length-of-day series spans January 20, 1962, to January 6, 2001, at daily intervals.
