Which phenomenon exacerbates tsunami height during subduction zone earthquake events?

💡 Explanation

When a subduction zone earthquake occurs, the fault rupture angle significantly influences tsunami height because a steeper angle promotes greater vertical displacement of the seafloor, displacing more water. Therefore fault angle uplift results, rather than liquefaction, root collapse or ash cloud which cause only secondary effects.
