Update 09:00 UTC:
The preliminary data released by the CEA and USGS show that this magnitude-6.3 earthquake originated from the northern part of the Tian Shan mountain range, at a depth of about 11 kilometers.
Though this M 6.3 earthquake occurred very soon after the earlier Mw 6.5 earthquake in Sichuan, and both events were caused by the Indian-Eurasian plate collision, these two events are likely to be separate due to the distance between them.
The Xinjiang earthquake is associated with the reverse fault (thrust fault) underneath Tian Shan.
Although China is located far from the major fault at the Indo-Eurasian plate boundary - the Himalayan Frontal Thrust - the powerful northward tectonic collision between the Indian and the Eurasian plates created a wide deformation zone within inner China. This is evident from the long history of earthquakes written into Chinese literature, including the destructive 2008 Wenchuan earthquake.  (Source: Singapore earth observatory).

Hard to say which fault plane is the right one in this case.

    People :
    Felt by persons at rest, on upper floors or favorably placed.
    MMI III (Weak shaking) ?
    People :
