Explosions

A large explosion erupts in the distance behind a rural road, sending a fireball and smoke plume into the sky, while a person on a bicycle rides toward the horizon; the scene cuts to a building with a similar explosion on its roof, then to a cityscape where a massive fireball and smoke cloud rise above the buildings, followed by a close-up of an explosion with debris flying, and finally a wide shot of a city with multiple large explosions and smoke clouds.
