Which risk increases when a megathrust earthquake stalls?

💡 Explanation

Elevated aftershock magnitude and frequency occurs because fault locking impedes stress release along the rupture surface, therefore aftershocks redistribute remaining stress rather than the main rupture propagating fully. Other answers are not direct consequences.

• Which outcome occurs when a lake's outflow threshold breaches?
• Which glacial outcome results when isostatic depression rebounds unevenly?
• Which consequence results when increased organic acid production occurs within cave stream sediments?
• Which effect happens when deep ocean brine drains?
• Which outcome results when consistent unidirectional winds impact deposition off barrier islands?
• Accelerated weathering of amphibolite bedrock causes what outcome due to resultant differential pedogenesis?
