Which risk increases when a hydroelectric dam is built across a transform fault?

💡 Explanation

Reservoir-triggered seismicity becomes highly probable, because the added water pressure along fault lines can overcome static friction via pore pressure induction, therefore increasing fault slip likelihood, rather than causing geothermal heating or bioaccumulation that require quite different initial conditions.
