Which risk increases when an earthquake occurs in a region with unconsolidated, water-saturated sediment?

💡 Explanation

When seismic waves pass through unconsolidated, saturated sediment, liquefaction occurs because the pore water pressure increases, reducing effective stress and causing the soil to behave like a liquid. Therefore structural collapse results, rather than tsunami generation, landslides or volcanic eruptions which entail separate triggering mechanisms.
