← GeographyNear a continental transform fault, which process most frequently causes shallow-focus earthquakes?
A)Elastic rebound from friction lock✓
B)Mantle plume volcanic eruptions
C)Subduction zone slab rollback
D)Isostatic adjustment after glaciation
💡 Explanation
Near transform faults, plates slide past each other; stress builds as friction resists movement, causing elastic deformation until overcome resulting in sudden release and earthquakes. Therefore, elastic rebound is the primary cause, rather than volcanic eruptions, slab rollback that are not associated with transform faults, or isostatic adjustment which are slow, gradual processes.
