(meteorobs) Big bolide in Lanzhou China (Dec.11/12)

[叶]

Hi,
  On Dec.11, about 23:36 (local time, = 15:36UT), many citizens of Lanzhou reported there was a "sun-like" object move eastwards, then there were loud sounds like bomb blast. After the bolide fell they noticed there was a red cloud in the sky. 
  The geophones around Lanzhou show something interesting too, a strange earthquake-wave was pick up at 23:38:43, equal an 1.5 level earthquake.
  Some experts went to Lanzhou, to search the possible aerolite, but nothing has been found. They thought the aerolite has fell into the hill around Lanzhou, and the hills are difficult to climb to search the possible aerolite.
