Answer: The beach becomes narrower and the cliffs behind it are subjected to a higher rate of erosion.
Explanation:
Building a dam on a river that flows to the sea makes the coastal beach narrow, and the cliffs behind it become subject to a higher rate of erosion.
Due to the damming of inflowing rivers, the sediment supply to the coastal shore becomes limited, making the coast on the opposite side of the dam more vulnerable to coastal erosion. Dams accumulate a significant volume of sand, reducing the amount of sand accessible to beaches, which narrow as a result.
It along plate margins. Where plates collide, run along side each other or if one subducts under another, If it gets caught/jammed, over time pressure builds and eventually it gives way, BOOM! The pressure is released as an earthquake. I guess inside the earth, the mantle is included but not hugely. Plates subducting might may cause friction to build up and cause the rock to melt and/or when it subducts into the mantle. But as it does, the pressure builds up again which will in tern cause a volcanic eruption.
