A giant glacier wall collapses into a fjord beside a coastal city

A giant glacier wall collapses into a fjord beside a coastal city. The falling ice triggers a massive water displacement wave that surges toward the harbor. Camera sweeps over the collapsing glacier before racing toward the city as the water wall crashes into buildings and docks. Icebergs smash through streets as the city floods. Glacier collapse megaflood, iceberg destruction chaos, cinematic polar disaster scale, 4K.
