It has already been published and presented in a geology conference:
It has been discovered that the Earth´s rotation slows down a few milliseconds every so often, and when it slows down, about 5 years later there is a 5-year period where the frequency of large earthquakes around magnitude 7 or greater increases about 20-30%.
So according to scientists, in 2018, around the tropical areas, we should expect around 20 major earthquakes, compared to the 15 average on a normal year.
JW´s are likely to jump on this as "evidence" of the time of the end, and will probably be misquoted in a Watchtower publication sometime soon.
Here are some news organizations covering the story:
Here is the scientific paper (which I can´t read but if someone has access to the PDF, could you please share)?
Here is the presentation to the Geological Society of America:
The two scientists who are in the paper are Roger Bilham and (Rebecca)? Bendick.
