Japan earthquake: Buildings crumble, close calls

(CBS) In amateur video of Japan's massive earthquake, a store clerk is seen wide-eyed behind the counter of a shop.

The earthquake's force violently shakes her surroundings; hanging lights sway like pendulums and shelved items scatter to the floor.

Next, a building in Sendai begins to crumble.

Pedestrians are seen rushing outside, covering their heads as chunks of debris fall to the ground.
