Update 10:42 UTC : The only positive fact about this latest aftershock is that a lot of people who lived in already damaged houses are now living in relief tents (some spend the rest of the day in the open air). This part of Yunnan is a subtropical area so no real problem with temperature.

Update 10:33 UTC : Another even slightly stronger aftershock has happened at 10:20 UTC - Chinese authorities reported M5.9 at a depth of 10 km. Same epicenter as the M5.8. This aftershock will certainly increase the damage of the earlier aftershock but will also put in danger the relief and rescue forces dispatched earlier today.

Update 09:08 UTC :  200 Jinggu police personnel have been send to the earthquake zone.

Update 08:57 UTC :  At the time of writing this update, the Chinese seismological authority measured 146 aftershocks. Only 1 in between 4 and 4.9 and 3 in between 3 and 3.9. The maps below are showing the epicenter in relation to the past seismicity.

Update 08:45 UTC : The number of injured did increase to 9 - At least 12 houses collapsed and many others were seriously damaged during this quake. Rescue and relief services have been send to the earthquake hit cities like Yongping. A lot of infrastructure like schools, government buildings, telecommunication equipment, water pipes atc were also damaged.

Update 23:32 UTC : The Yunnan Emergency services are reporting that at least 5 people have been injured by this earthquake. 25 rescue and relief teams have been send to the epicenter are to do assessment and to give give the first help to the victims.

Update 23:29 UTC : We cannot find a lot of details as yet (will certainly arrive the coming hours) but what we know so far is that the Yunnan Seismological Bureau has called a level III emergency situation which means that they consider this earthquake as very dangerous

Update 19:47 UTC : As usual in China, the focal mechanism shows a dangerous strike-slip mechanism = the most dangerous type in the world. Based on the M6.1 earthquake we expect a North-West to South-East acceleration.

Faults as published during the Mainshock - The red star is the epicenter of the M6.1 mainshock

Update 19:45 UTC :  We expect that it will last at least 3 to 4 hours before we will know more details from the earthquake region

Update 19:08 UTC : CEIC China reports a M5.8 at a depth of 9 km (extremely dangerous cocktail)

Update : dangerous earthquake in a luckily not so populates area, but still strong enough to be surely very damaging. The M6.6 mainshock generated a lot of damage and counted 1 fatality and 324 injuries!

Shaking Strength *
MMI II (Very weak shaking) ?
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.
Fittings :
Doors and windows rattle. Glassware and crockery rattle. Liquids in open vessels may be slightly disturbed. Standing motorcars may rock.
Structures :
Walls and frames of buildings, and partitions and suspended ceilings in commercial buildings, may be heard to creak.
MMI V (Moderate shaking) ?
People :
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.
Structures :
Some large display windows cracked. A few earthenware toilet fixtures cracked.
MMI VI (Strong shaking) ?
People Felt by all. People and animals alarmed. Many run outside. Difficulty experienced in walking steadily.
Fittings :
Objects fall from shelves. Pictures fall from walls. Some furniture moved on smooth floors, some unsecured free-standing fireplaces moved. Glassware and crockery broken. Very unstable furniture overturned. Small church and school bells ring. Appliances move on bench or table tops. Filing cabinets or "easy glide" drawers may open (or shut).
Structures :
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.
Structures :
Unreinforced stone and brick walls cracked. Low standard buildings cracked with some minor masonry falls. A few instances of damage to buildings of ordinary workmanship. Unbraced parapets, unbraced brick gables, and architectural ornaments fall. Roofing tiles, especially ridge tiles may be dislodged. Many unreinforced domestic chimneys damaged, often falling from roof-line. Water tanks Type I burst. A few instances of damage to brick veneers and plaster or cement-based linings. Unrestrained water cylinders (hot-water cylinders) may move and leak. Some common windows cracked. Suspended ceilings damaged.
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. A few instances of damage to buildings and bridges designed and built to resist earthquakes. Monuments and pre-1976 elevated tanks and factory stacks twisted or brought down. 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. Environment : Cracking of ground conspicuous. Landsliding general on steep slopes. Liquefaction effects intensified and more widespread, with large lateral spreading and flow sliding adjacent to streams, canals, lakes, etc.
