Which risk increases when a fault's asperities fail?

💡 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.

• Which mechanism distributes floating plastics throughout the North Pacific Gyre?
• Which outcome occurs when sediment supply exceeds stream transport capacity near a mountain front, promoting widespread aggradation?
• Which pedological outcome results when high rainfall increases?
• Which outcome occurs when thermal gradients accentuate the Coriolis effect?
• Which outcome results when groundwater carbonate saturation decreases in caves?
