摘要
利用甘肃省地震局在兰州市区及附近布设的数字地震台网的记录资料,对2004 年12 月11日兰州陨石坠落的过程进行了初步反演和分析。结果表明,23时36分23秒陨石进入兰州地区26km的上空,经历过一次较小的爆炸,然后向东北方向坠落,于23 时36 分42 秒在13 km高空发生最终爆炸解体,没有较大陨石体坠落地面。
The falling process of Lanzhou meteorite in Dec. 11, 2004 is conversed and analyzed using the seismic data recorded by the Lanzhou temporal digital network set by Seismological Bureau of Gansu Province. The results show that the meteorite came into the sky above Lanzhou through 26 km high at 23:36:23 in Dec. 11, 2004, and a small explosion occurred, then the fireball fell down towards to the north-east direction, arrived its endpoint and exploded and disjointed into Key words: small ones Meteorite; at 23:36:42 at 13 km high. No big ones fell down to the ground Lanzhou area; Seismic records
