Update 10:00 UTC: ER congratulates the Mexican government for their swift assessment and response after the earthquake. Governors were quick to respond with news bulletins via social media.

Update 09:51 UTC: NO fatalities (except for the helicopter accident) and only 2 injured people is the VERY POSITIVE outcome after this potentially very dangerous earthquake. The earthquake type as well as the location of the epicenter are the most important reasons that this earthquake has a relative happy end.

Update 09:24 UTC: A sad accident took place after the earthquake when an helicopter transporting SGOBMX personnel crashed while landing in damaged Jamiltepec killing 2 people on the ground. As these are not fatalities directly related to the earthquake, we will not count them to register this earthquake as a deadly earthquake.

Update 09:21 UTC: Power was lost for 109,000 people in the Oaxaca province: governor Alejandro Murat
In total more than 900,000 people were affected by the loss of power. Power was however reestablished soon for most of them.

Update 09:10 UTC: Seismologist Jascha Polet : Cross-section of seismicity near today's M7.2 indicates that the earthquake occurred in a region of flat slab subduction, near the bottom of the coupled zone, on the interface between the two plates.

Update 09:06 UTC: Seismologist Robin Lacassin : Yesterday Mexico M7.2 #earthquake: thrust mechanism with NE dipping plane compatible with subduction #megathrust (but hypocenter depth 20-25km perhaps too shallow). Simple source time function hints for probable simple rupture.All solutions for M7.2 #Mexico #earthquake = confirm thrust mechanism. Depth estimates range between 15 & 26km (quite shallow, but 25km may be just compatible with megathrust).

Update 09:04 UTC: Geologist Dr. Jay Patton : Possibly too shallow for megathrust. only mapped fault is Chacalapa fault, a sinistral strike-slip fault, may have thrust motion in places. Duncan F Keppie 2009 PhD

    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 :
    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.
