← GeographyWhich crustal deformation occurs when locked fault segments rupture during an earthquake cycle along a subduction zone?
A)Elastic rebound causing tsunamis✓
B)Isostatic uplift forming terraces
C)Abyssal plain subsidence creating trenches
D)Magmatic intrusion initiating plutons
💡 Explanation
When plates are locked, elastic strain builds until the rupture threshold is reached, releasing energy during an earthquake, causing elastic rebound and vertical displacement of seafloor generating tsunamis. Therefore elastic rebound results, rather than uplift, subsidence, or intrusion related to other geological processes.
