is there any relation between dam and earthquake? explain
Answers
Dams by itself do not cause any earthquake. The purpose of any dam is to impound the flowing water. This leads to formation of reservoir in which a large portion of land is submerged along with the river course on which the dam is made. This leads to increase in the pore-water-pressure of that area. If ther happens to be any known fault plane in the reservoir area, this sudden increase in pore-water-pressure may lead to increase seepage in the subsurface and eventual low of water along the fault-plane. In this worst-cenario this may lead to triggerring a slip on that fault plane due to lubricant action of water-flow. This is called reservoir-induced earthquake.
so, from the above information we can conclude that there is a relation between dams and earthquake!
hope it is helpful!✌️
earth is big, and so are the tectonic plates—it doesn’t seem possible that anything humans could do to the earth would have an effect on those immense plates. But evidence is mounting that we cause earthquakes.
I listened in fascination to a presentation from earthquake scientist Christian Klose at the 2006 American Geophysical Union fall meeting in which he showed how coal mining was responsible for earthquakes, including the most-damaging ever in Australia. (The 5.6-magnitude Newcastle earthquake of 1989, though relatively small by international comparison, killed 13 people.) The removal of coal, rock and, especially, water from underground can cause enough stress to trigger an earthquake, Klose said. Other potential earthquake triggers he mentioned were oil and gas extraction, creation of reservoirs behind dams and, he conjectured, sequestering carbon dioxide underground.
