A towering wave slams into a bustling port under storm-gray skies, sending shipping containers tumbling like toy blocks. The sea surges inland with impossible strength, lifting parked cars from the lot and swirling them around like leaves in a whirlpool. Alarms blare and metal groans as vessels break from their moorings. Sparks flash from broken electric poles while crates, buoys, and oil drums crash into warehouses and docks, the water rising fast and cold as the chaos spreads inland.
