Which risk increases when an earthquake occurs near fine-grained unconsolidated sediment deposits?

💡 Explanation

When an earthquake occurs near unconsolidated sediments, liquefaction can occur because seismic waves increase pore water pressure, reducing effective stress and causing the soil to behave like a liquid, which leads to structural collapse. Therefore liquefaction is more likely, rather than tsunami generation, pyroclastic flows or acid rain which require specific geological or atmospheric conditions.
