THE CHELYABINSK,RUSSIA,METEORITE FALL

摘要

On February 15, 2013, at 9:22 am, a spectacular meteor blast above the city of Chelyabinsk, Russia, sent a shock wave across the region. The bright fireball (Fig. 1) was seen by numerous observers in parts of the Kurgan, Tyumen, Ekaterinburg, and Chelyabinsk districts. The shock wave, resulting from the explosive deceleration and breakup of the meteoroid in the Earth's atmosphere, caused structural damage to buildings, shattered windows, and injured an estimated 1200 people in the city of 1.1 million. A part of the roof and a wall of a zinc plant and a stadium in Chelyabinsk were also damaged.
