← GeographyWhich risk increases when poorly designed buildings experience liquefaction?
A)Settlement cracking around the foundation
B)Catastrophic structural shear failure occurs✓
C)Increased material tensile stress emerges
D)Amplified rebar corrosion accelerates dramatically
💡 Explanation
Catastrophic structural shear failure increases because liquefaction reduces soil strength, and seismic energy causes buildings to move differentially, thus inducing shearing; therefore, shear failure is amplified rather than settlement because settling is a slower geological shift.
