Which risk increases when a megathrust fault experiences creep?

💡 Explanation

Episodic tremor and slip (ETS) risk increases because fault creep episodes can trigger ETS events involving the aseismic slip and associated tremors, rather than a significant earthquake. Therefore, option A is the result of fault creep rather than others.

• Which outcome occurs when unprotected prairie soil experiences intense 'Chinook' winds?
• Which landscape outcome occurs with prolonged katabatic wind erosion?
• Which outcome occurs when rapid alluvial deposition obstructs established waterways?
• Which outcome is least likely as deposition shifts laterally on an alluvial fan constrained by uplift?
• Which risk sharply increases along Arctic pipeline routes when ambient temperatures rise above freezing?
• Which outcome is more likely after prolonged abrasion by saltating sand particles?
