← GeographyWhich outcome disproportionately amplifies tsunami risk when basaltic lava flows enter coastal regions?
A)Increased crustal subsidence
B)Enhanced wave reflection✓
C)Accelerated isostatic rebound
D)Elevated pore water pressure
💡 Explanation
Wave reflection is amplified because basaltic lava rapidly cools upon contact with seawater, forming solidified coastal protrusions and rough coastlines; therefore, wave energy is redirected seaward causing stronger waves rather than dissipating inland.
