Mystery solved: India's 2d seismic survey reveals ancient city!
A 2D seismic survey in India is a type of survey used to collect data about the interior of the Earth. This type of survey is done using two or more seismic waves, which are created when an object, like a rock, is disturbed. The waves travel through the ground and reflect off objects along their way. By measuring the time it takes for these waves to reach different parts of the Earth, scientists can determine information about the rocks and soil in that area.
