← GeographyWhich risk increases when earthquake-induced liquefaction weakens ground infrastructure on a coastal slope?
A)Accelerated coastal erosion rates✓
B)Increased frequency of tsunamis
C)Decreased marine biodiversity
D)Reduced atmospheric carbon sequestration
💡 Explanation
When liquefaction weakens coastal slopes following an earthquake, soil shear strength decreases because pore water pressure increases, leading to slope instability and accelerated mass wasting. Therefore accelerated coastal erosion results, rather than tsunamis, biodiversity changes, or carbon sequestration shifts, which involve distinct geophysical processes.
