The Southern sea of Sri Lanka has been identified as the region with the lowest gravitational pull in the world, geologists said. According to researching scientists a particular reason behind this low gravity had not yet been discovered. Professor of Geology Wilbert Kehelpannala of Peradeniya University told Daily Mirror that scientists were still researching on factors which cause low
gravitational regions in the world but no explanation had been discovered so far.
“Gravitational power is a factor which depends on the density of basic rock and its calculation is a complex process. It is determined according to the density of the basic rocks as well as considering the topography of a region. Usually if the density of the basic rocks is high, the gravitational power should be high too,” explained Prof. Kehelpannala.
He added however in certain regions the trend differs whereas the basic rock density contradicts with the gravity power. “In such situations the basic rock density might be high but the gravity would be low or vice versa. This results in a gravity anomaly, otherwise known as a Bouguer anomaly and the South sea of Sri Lanka has the lowest in the world,” he stated.
