Scientists have discovered what they say is a correlation between major  earthquakes and the Earth's rotation which seems to spell trouble for  2018.

In a recently published paper, a pair of scientists detailed how, while  studying data on magnitude 7 or higher earthquakes since 1900, they  spotted five periods in which the disasters occurred with unusual  frequency.

An attempt to find some connection to these curious outliers eventually  led to them to notice that each of these earthquake spurts appeared to  happen five years after the Earth's rotation had slowed.

Even though the change is imperceptible to humans, it apparently has a  dramatic effect on seismic activity, the scientists argue, although they  concede that the reason why remains a mystery.

Nonetheless, the researchers say that the relationship is quite apparent  and that their findings come at a particularly important and worrisome  time.
