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 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.

Dams are huge barriers built across rivers and streams to confine and utilize water for irrigation and electricity supply.
Dams (water reservoirs) could cause earthquakes due to change in stress because of the weight of water or by increased groundwater pore pressure.
The increased pore pressure leads to decrease in the effective strength of the rock under the reservoir.
The extra water pressure created in the micro cracks and fissures in the ground under and near dams can cause earthquakes.
