Which outcome elevates earthquake risk due to lake impoundment?

💡 Explanation

The outcome is increased earthquake risk; reservoir-induced seismicity arises because of increased pore water pressure triggering fault slip; the effective normal stress decreases, therefore failure occurs, rather than if shear stress decreased or sedimentation was enhanced.

• Which outcome occurs when stress rapidly accumulates along a transform plate boundary below a large artificial reservoir?
• Which geological change results when thermal convection weathers a subducting oceanic plate?
• Which risk increases during prolonged flooding of alluvial plains containing fine silt deposits?
• Which crustal deformation results when high-viscosity lava cools within volcanic vents?
• Which risk increases when increased glacial melt leads to decreased salinity in North Atlantic gyre surface waters?
• Which fault behavior results when fault creep slows?
