← GeographyWhich risk increases when a fault's asperities fail?
A)Increased frequency of seismic creep✓
B)Heightened risk from volcanic eruptions
C)Decreased surface rupture displacement
D)Reduced geyser activity nearby thermal vents
💡 Explanation
Increased frequency of seismic creep will be triggered; fault asperities usually prevent continuous ‘stick-slip’ behavior – with smaller irregularities failing allows low magnitude/high frequency events rather than fewer high magnitude events, because strain energy accumulates across smaller locked areas therefore triggering more frequent motion.
