← GeographyWhich landslide risk increases when earthquakes occur on steep, deforested slopes with saturated soil?
A)Increase in liquefaction-induced lateral spreads
B)Increase in debris flow volume potential✓
C)Increase in creep deformation rates
D)Increase in rotational slump stability
💡 Explanation
When earthquakes occur, ground shaking destabilizes the saturated soil on steep, deforested slopes triggering increased debris flow volume due to reduced soil cohesion. Therefore, increased debris flow potential is more likely, rather than liquefaction which requires specific soil composition, creep which is slow gradual movement, or slump stability.
