← GeographyWhich outcome occurs when stress rapidly accumulates along a transform plate boundary below a large artificial reservoir?
A)Increased frequency of minor fault creep
B)Triggered seismicity from stress perturbation✓
C)Localized subsidence from sediment compaction
D)Enhanced geothermal activity from fluid flow
💡 Explanation
When stress accumulates and a reservoir load is applied, static stress transfer occurs because the water increases pore pressure, reducing effective stress, causing triggered seismicity. Therefore increased likelihood of earthquakes results, rather than fault creep, land subsidence, or geothermal enhancement, conditions for which are not created.
