Which outcome of a megathrust earthquake increases slope instability?

💡 Explanation

Localized ground shaking initiates liquefaction; this mechanism decreases sediment shear strength because pore water pressure increases significantly. Therefore, hill slope stability is severely compromised causing landslides, rather than albedo changes or fault alterations.

• Which outcome occurs when the viscosity of rhyolitic lava decreases within a stratovolcano during a fissure eruption under increasing hydrothermal pressure?
• Which process drives cirque formation when glacial ice accumulation fluctuates?
• Which outcome will occur when a river's discharge decreases significantly across an active alluvial fan?
• Which climate outcome results when a meandering jet stream amplifies atmospheric blocking over major river systems?
• Which outcome results when rapid levee consolidation occurs?
• Which primary mechanism causes cyclical avulsions on the apex of an alluvial fan?
