Which process significantly increases tsunami risk in fjords?

💡 Explanation

Submarine landslides within fjord basins cause increased localized tsunami hazards, because displacement from slumping causes focused wave amplification, thereby leading to higher run-up heights rather than diffraction occurring because of geometry.

• Which mechanism causes crustal thinning directly above a strike-slip fault zone?
• Which risk increases when an alluvial channel experiences increased sediment load during flash flooding?
• Which pattern develops when intense earthworm activity disturbs soil stratification?
• Which mechanism causes deflection of ocean currents due to Earth's rotation, primarily affecting their direction?
• Which hazard intensifies due to increased pyroclastic density?
• Which outcome develops when longshore currents encounter a headland?
