One of the most wondrous secrets is that during British rule in our country, they made the decision to develop a blueprint to restore the original borders of a place if they were distorted by an earthquake. One remarkable aspect of this blueprint is that it consists of three access points to detect the distorted places. These points are located at Kodaikanal hills, another one at Tirumala hills, and the finishing point is at Kondarangi hills, locally named Malleeswaran Kovil. This framework, developed by the British, is known as the Triangle Survey. This survey has been found to be useful in generating reports on the measurements of new land in Tamil Nadu if it is affected by a severe earthquake.
