USGS Chamberlain, South Dakota Feb 07 20:49 2.9 14 MAP I Felt It
EMSC South Dakota Feb 07 20:49 2.9 14 MAP I Felt It
USGS Custer, South Dakota Dec 12 09:43 3.5 4 MAP I Felt It
  • Custer - I woke up in the middle of the night for no reason. Sounded like someone was knocking on my storm door. Dog was pacing around the bedroom and huffing like he was about to bark but settled down in less than a minute.
  • EMSC South Dakota Dec 12 09:43 3.5 5 MAP I Felt It INFO
  • Hermosa SD - Unknown at this time
  • Hermosa - My wife and Dog woke me up and said the house shook violently. Dog was pretty ruled up and so was wife.
  • Rapid City/Rapid Valley - Felt a vibration and thought it was a snow plow. Dog was barking.
  • Rockerville, SD - We did not see any damage to our property. I did not know South Dakota experienced earthquakes until now.
  • Hermosa - my husband, daughter and i awoke to the house shaking
  • Rapid City - There was no damage. I was at work and felt the ground shake and others felt it too. It was very light shaking.
  • Keystone - I was at work and heard it, but barely felt it. It lasted less than a second. No damage that I am aware of.
  • Hermosa - Awakened by a rumble like thunder, followed by a "bump" and felt the house move. Heard things on walls rattling. Lasted only a couple of seconds. My daughter (in the same home) described being awakened to the same experience.
  • Hermosa - I'm not sure if I even know the range of very weak to violent shaking as I have never experienced it before. It "growled". Wondered if it was a huge semi that went by--but that did not make sense because vehicles have never had that effect before. However, I wasn't sure what it was until people told me much later in the day. I have no idea of damage--I don't think so.
  • Rapid City - I woke up in a panic - I thought our house was being broken into. I didn't even know there was an earthquake until the next day, but waking up in that way made sense since there was an earthquake.
  • Ottawa - I felt it in Ottawa, Kansas. I was at a party, but I was the only one there that noticed. It was a brief movement, like the feel of a floor moving near an elevator.
  • Custer - I woke up but didnt know why. The cat was bouncing off the walls after that!
  • Hermosa South Dakota - Felt like a natural gas explosion. @-4 second rumble and vibrations
  • Hermosa - My husband felt the house shake & thought someone had run into the garage!
  • Rockerville, SD - January 5, 2015 approximately 9:10am. Was sleeping with my little dog and was awakened by "something" which was shaking. My dog was shaking and clamoring for my chest and neck, which he does only when he's super scared. Bed felt like the massager was on but the remote wasn't even on the bed. Weird Schneider.!!??

    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) ?
    People
    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.
