  • Tinker AFB - Sitting in my office, I felt a sudden jolt. Walls shook, etc. The whole building felt it. Some even went outside to see if something had hit the building.
  • Tinker AFB. - It was almost like one quick shake! The only thing I know to compare it to, is incoming mortar fire.
  • Near MWC hospital - House and walls shook, no damage noted. Believe it was closer/stronger than prior shakes felt by us.
  • Edmond - Sounded like shelves collapsing somewhere in the house, rattled the 55 gallon fish tank.
  • Midwest City - I would not say shaking, more like a drop fault type of earthquake. Short and noisy.
  • Downtown, Oklahoma Tower - From the 30th Floor of the Oklahoma Tower it felt like slight rumbling and made my stomach feel queasy.
  • Tinker AFB - Strong shake in the interior of 3rd floor of building.
  • Del City - While in the bathroom, I heard a small boom and the house shook a tiny bit. Cat meowed its "What's going on" meow from the garage. Nutty dog slept in the sun outside through the entire event. I agree with the person who wrote it seemed like a drop fault.
  • Memorial & Santa Fe - Working and it sounded like something crashed into the wall next to me.
  • Del City - One hard jolt like after an explosion but no boom. It jolted me in my chair and my whole desk.
  • Benham building 7th floor - Early afternoon I felt the floor of the 7th floor shaking.
  • Broken Arrow, Ok. - Not too sure what it was, heard a very low rumbling boom and house just sort of trembled lasted about 2-3 seconds,sounded almost like something hitting the house, then heard a louder boom to the So. of our house then nothing. Could it have been a sonic boom? We are so far away from OKC. And I heard and felt this at 11:30 A.M.Looked outside and didn't see anything.
  • OK - Seemed the house went both back and forth.
  • SW 104th & May, OKC - It felt like the chair I was in dropped a fraction of an inch with a quiet thump. Almost didn't notice it, but it caught my attention. Wondered if that what it was.
  • Tinker AFB - Sitting in the Dinning room working on paperwork at my restaurant i felt the table shake and felt a small vibration. When I asked workers "did you feel that" a lot of them did not.
  • USGS Oklahoma Feb 27 12:30 2.5 4 MAP I Felt It
  • Midwest City - The quake was felt on the second floor of the Midwest Regional Medical Tower akin to a swift shake/low rumble that lasted two to three seconds. The building felt safe though there was the feeling of an old roller coaster track, or even a farm truck on a gravel road.

    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.
