← GeographyWhich outcome results when shallow-focus subduction earthquakes induce deformation?
A)Tsunami generation via seafloor displacement✓
B)Enhanced geothermal vent activation
C)Increased rate of glacial calving
D)Accelerated chemical weathering of bedrock
💡 Explanation
Tsunamis are linked to shallow-focus earthquakes because fault rupture causes vertical seafloor displacement; this induces a large water column to be displaced through elastic rebound, therefore causing a tsunami, rather than increased geothermal vents.
