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.
