How did an earthquake 2,500 years ago change the Ganga river's course abruptly

1. Intense seismic activity during the earthquake caused disturbances in the tectonic plates beneath the Ganga river. 2. The movement of the tectonic plates led to the sudden shifting of the river's course. 3. The abrupt change in the river's direction altered the landscape and affected the flow of the Ganga river. 4. Geological evidence, such as sediment layers and landform changes, supports the theory of this earthquake-induced course change. 5. This event from 2,500 years ago highlights the impact of natural disasters on shaping geographical features and influencing water bodies like the Ganga river.
