Moreover, as the Earth’s rotation has been experiencing this exact type of slowdown, we may be due for this exact uptick in earthquakes just next year. While media coverage, as always, is breathless, there are a number of more sober takes saying that we might not have more earthquakes next year after all. The important thing to take away is that:we have had periods over the last century where greater numbers of more powerful earthquakes have occurred,there is a relationship between these periods and the slowing rotation of the Earth,and we’ve been going through another period of slowing rotation.Will there be more earthquakes next year? And if so, why? Let’s look at the science to find out.The layers of ...
