Which risk increases when plate boundary displacement exceeds frictional strength?

💡 Explanation

Increased megathrust earthquake propagation results because strain accumulates until static friction is overcome, triggering stick-slip behaviour. This results in rapid rupture propagation rather than slower creep, therefore leading to larger ruptures, rather than mineral stability, or vent/fault changes.
