Which risk increases when a large inland reservoir experiences rapid drawdown during the seismically active period?

💡 Explanation

When the rapid drawdown is happening, crustal unloading occurs because the water pressure on the underlying rocks greatly decreases within the seismically active region, leading to increased potential for fault slip and induced earthquakes. Therefore induced seismicity significantly raises, rather than stratification, eutrophication or slope failure which require thermal or geological conditions.
