Which mechanism contributes to tsunami formation along subduction zone fault lines during earthquakes?

💡 Explanation

During subduction zone earthquakes, abrupt vertical displacement of the seafloor occurs because fault rupture causes the overriding plate to shift, displacing a large water volume upwards. Therefore, vertical displacement causes tsunamis, rather than resonance, methane release, or landslides which depend on different triggers.
