  • Chengdu - Sol qui a tremblé nous sommes au 10eme étage de l'hôtel
  • Xi'an - Moderate shaking
  • Chengdu - Building swayed gently 5 times, over about 6 seconds. It is a 15 story building. I was in the middle.
  • Zhengzhou - Shaking lasted about 5-10 seconds
  • Chengdu - It was very weak shaking, I noticed the tv moving a bit
  • Chengdu - Barely noticed shaking on ground floor, but my wife lying in bed in 15th floor apartment reported dizzy wave for 15 seconds whilst lying on bed. Immediate reactions on my wife's WeChat feed from friends, including video footage from a friend driving near MianYang showing landslides on highway. Chengdu hospitals were sending all available ambulances within the hour. Limited information on News feeds, only information through private accounts and first hand witnesses who are friends.
  • Ankang, Shannxi - We are very far from where the Earthquake took place. I actually thought something was wrong with me, I felt myself moving slightly, left to right and dizzy just for about 20 seconds. First time I felt this.
  • xi'an - Strong shaking
  • Xi'an - We live on the 29th floor. We saw the lights swinging around violently and we didn't really feel the floor move. I guess it is just a lot worse if you live up this high. The neighbours on the first floor were almost undisturbed. It all lasted several minutes (it felt like that)
  • Deyang - Weak shaking
  • Chengdu - Bed swayed ever-so-slightly for a couple of seconds. On 6th floor of hotel. First thought: earthquake? Second thought: imagination. Upon waking this morning, I find that my first reaction was, sadly, correct.
  • Deyang City - no damage, but i was frightened.
  • Chengdu - From 30th floor first shaking then swaying lasting 30seconds. Strong enough to get a supplies bag to evacuate

    People :
    Felt by persons at rest, on upper floors or favorably placed.
    MMI III (Weak shaking) ?
    People :
    Felt indoors; hanging objects may swing, vibration similar to passing of light trucks, duration may be estimated, may not be recognized as an earthquake.
    MMI IV (Light shaking) ?
    People :
    Generally noticed indoors but not outside. Light sleepers may be awakened. Vibration may be likened to the passing of heavy traffic, or to the jolt of a heavy object falling or striking the building.

    Generally felt outside, and by almost everyone indoors. Most sleepers awakened. A few people alarmed.
    Fittings :
    Small unstable objects are displaced or upset. Some glassware and crockery may be broken. Hanging pictures knock against the wall. Open doors may swing. Cupboard doors secured by magnetic catches may open. Pendulum clocks stop, start, or change rate.

    Slight damage to buildings with low standard. Some stucco or cement plaster falls. Large display windows broken. Damage to a few weak domestic chimneys, some may fall.
    Environment :
    Trees and bushes shake, or are heard to rustle. Loose material may be dislodged from sloping ground, e.g. existing slides, talus slopes, shingle slides.
    MMI VII (Very strong shaking) ?
    General alarm. Difficulty experienced in standing. Noticed by motorcar drivers who may stop.
    Fittings :
    Large bells ring. Furniture moves on smooth floors, may move on carpeted floors. Substantial damage to fragile contents of buildings.

    Environment :
    Water made turbid by stirred up mud. Small slides such as falls of sand and gravel banks, and small rock-falls from steep slopes and cuttings. Instances of settlement of unconsolidated or wet, or weak soils. Some fine cracks appear in sloping ground. A few instances of liquefaction (i.e. small water and sand ejections).
    MMI VIII (Severe shaking) ?
    People Alarm may approach panic. Steering of motorcars greatly affected. Structures : Low standard buildings heavily damaged, some collapse. ordinary workmanship buildings damaged, some with partial collapse. Reinforced masonry or concrete buildings damaged in some cases.

Some pre-1965 infill masonry panels damaged. A few post-1980 brick veneers damaged. Decayed timber piles of houses damaged. Houses not secured to foundations may move. Most unreinforced domestic chimneys damaged, some below roof-line, many brought down. Environment : Cracks appear on steep slopes and in wet ground. Small to moderate slides in roadside cuttings and unsupported excavations. Small water and sand ejections and localized lateral spreading adjacent to streams, canals, lakes, etc.
    MMI IX (Violent shaking) ?
    Structures Many low standard buildings destroyed. Ordinary workmanship buildings heavily damaged, some collapse. Reinforced masonry or concrete buildings damaged, some with partial collapse. Buildings and bridges designed and built to resist earthquakes damaged in some cases, some with flexible frames seriously damaged. Damage or permanent distortion to some buildings and bridges, designed and built to normal use standards. Houses not secured to foundations shifted off. Brick veneers fall and expose frames.
