According to scientists from the University of Colorado, there is a strong link between the Earth's rotation and seismic activity. Several scientists have warned that there could be a significant upsurge in number of earthquakes worldwide next year. It disbelieved that the variations in speed of the Earth's rotation could cause severe seismic and unstableness, specifically in tropical areas that are heavily populated.
Although the rotations may be very small, it is argued that even that could be enough to create big amounts of underground energy to be impactful. Researchers were studying to find out what is the correlation between periods with high number of earthquakes and intense seismic activity, along with other factors that contribute as well. What they discovered was that when "Earth’s rotation decreased slightly it was followed by periods of increased numbers of intense earthquakes." Even the slightest rotation of the earth can be measured and expected to create some kind of impact in terms of earthquake, big or small. Two researchers that embarked on the study found that there is a common period of about 5 years where the Earth's rotation slowed a specific amount several times throughout the past century and a half. Thus, these periods resulting in a noteworthy increase in intense earthquakes. According to Roger Bilham, "This link is particularly important because Earth’s rotation began one of its periodic slowdowns more than four years ago." Suggesting that the Earth is giving us a 5 year heads up on earthquakes to occur in the future.
