A massive tidal wave crashes into a coastal city. Buildings crumble as the wall of water surges through the streets. Cars are swept up and tumble through the flood. The camera captures the destruction from a rooftop as the wave passes below, water exploding against skyscrapers. Debris and foam churn in every direction. The sky is dark with storm clouds. Hyper-realistic, catastrophic scale, 8k, Roland Emmerich disaster movie, the deafening roar of a million tons of water.
