Final answer:
True. Tsunami currents are driven by the moving water underneath a tsunami, and exert forces that can be very large, because water is heavy.
Step-by-step explanation:
True. Tsunami currents are indeed driven by the moving water underneath a tsunami and they can exert very large forces due to the weight of water. These hazards include strong current forces and the formation of whirlpools. The force exerted by tsunami currents can cause significant damage to structures and pose a threat to human life.
