MAINSHOCK ARTICLE

Update May 13 : The mainshock caused at least 9500 houses to be damaged !

Update May 11 07:07 UTC : Below the SSN (Mexico) seismogram which shows the mainshock on top as well as 2 aftershocks. Just as shown in the 10:05 UTC update seismogram from yesterday, we do see a very extended vibration.

Update 09:04 UTC : Reader Micocolembo Quirocia wrote in our Facebook Page :  Oh well...I was presently in the same spot as the one on Thursday and today it felt as a 6.3 (at least the initial jolt) the only difference it was the duration, today´s duration was less

Update 08:30 UTC : Power went out for a couple of minutes in some parts of Mexico City

Update 08:22 UTC : The video below has been recorded in the same studio than the video we published in our mainshock article

Update 08:15 UTC : A lot of the damaged homes from the mainshock resulted in complete loss, some of them even collapsed. Today's aftershock will add to all this misery. Contrary to other countries, the Mexican authorities are not publishing detailed statistics about earthquake damage.

Update 08:07 UTC : NO spectacular damage so far. No injuries reported

Update 08:05 UTC : SSN Mexico (Mexican seismological agency) has decreased the initial reported Magnitude from M6.3 to M5.9

Update 08:04 UTC : Mexicans are getting used to these earthquakes and are returning gradually to their bed again

Update 08:01 UTC : It is currently the "middle of the night" in Mexico (03:02). A gas line broke in Azcapotzalco. 1000+ homes were damaged by the mainshock

Update 07:55 UTC : USGS has in the meantime downgraded the aftershock to M6.0 at a depth of

Update 07:54 UTC : Mexican civil defense (Proteccion Civil)  is reporting a possible downgrading of the Magnitude from 6.3 to 5.8 (a lot weaker)

Update 07:39 UTC : Apparently the early warning alerts have been going off as many people from DF joined us just after the quake. A difference compared to earlier this week is that the depth of the hypocenter has a preliminary value of 68 km = less dangerous than earlier this week if confirmed.

    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.

    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) ?
    People
    General alarm. Difficulty experienced in standing. Noticed by motorcar drivers who may stop.

    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.
