← GeographyWhich outcome results when a large, long-offset transform fault on the seabed ruptures?
A)Localized tsunami generation and propagation✓
B)Widespread methane hydrate destabilization
C)Rapid formation of new volcanic islands
D)Large-scale deep ocean current deflection
💡 Explanation
When a long transform fault ruptures, sudden vertical displacement of the seafloor occurs from strike-slip motion, due to elastic rebound, generating a tsunami that propagates outwards. Therefore, tsunami generation results, rather than methane release, volcanism or current deflection, which all require different triggers.
