Which outcome increases risks to structures built along a fault line running through alluvial deposits undergoing increased seismic activity?

💡 Explanation

Enhanced liquefaction and settling occur because seismic waves cause saturated alluvial soils to lose strength during shaking (soil liquefaction); therefore, structures become unstable. This is more significant than bedrock uplift, which is a slower, more even process, rather than causing sudden deformation.
