← GeographyWhich secondary effect is intensified when seismic retrofitting is selectively underfunded?
A)Amplified ground motion amplification
B)Increased primary wave resonance
C)Enhanced liquefaction susceptibility✓
D)Reduced building natural frequency
💡 Explanation
Liquefaction susceptibility increases because seismic retrofitting underfunding leads to structurally unsound soil; therefore the shaking causes soil to lose strength, rather than remaining stable. Amplification and resonance relate to wave features, not soil mechanics.
