CHELYABINSK, Russia — The shock wave from a meteor that exploded above Siberia last week somehow sheared the roof off a brick and steel factory building while leaving a nearby glass facade unscathed.

In some high-rises in this city, the first modern urban community to have felt the breath of a cosmic close encounter, every window blew out on the top floor; elsewhere, the ground floors suffered.

More ominously, reports came in to local news media over the weekend of stranger phenomena: behind unshattered apartment windows, glass jugs were said to explode into shards, dishes to crack, electronics to die. Balconies rattled. One man said a bottle broke right in his hand.

Anna V. Popova was at home with her daughter when she saw the flash, then heard explosions, then found the windows of her enclosed balcony blown in; her neighbor, with identical windows, escaped without property damage.
