Colossal Tsunami Coastal Catastrophe

A colossal, photorealistic tsunami towers over a modern coastal city at stormy dusk, an immense wall of dark blue water curling forward with unstoppable force, filled with swirling debris, dense foam, and wind-blown mist as lightning flashes through heavy storm clouds; a single continuous 15-second cinematic slow-motion shot with a smooth forward-moving camera as the wave rapidly advances, city lights flickering beneath the looming water mass, buildings beginning to buckle under pressure, and streets disappearing under rising floodwater; ultra-realistic fluid dynamics with detailed foam and particle simulation, volumetric lightning illumination, rich cinematic color grading in deep blues and stormy grays, subtle motion blur, highly detailed environmental destruction, no artifacts, seamless motion consistency.
