Update : Focal mechanism of this earthquake is a strike/slip mechanism (the most dangerous earthquake type as this has a dominant horizontal movement)

USGS Piedmont, Ca Mar 03 11:04 2.8 5 MAP I Felt It INFO
  • Lafayette - it woke me up. quick shake and I jumped out of bed at 3:11 a.m.
  • Berkeley - Very weak shaking
  • Oakland - I heard the earthquake go from piedmont to oakland.
  • Oakland - Lasted only a couple seconds, rattled my bed, no damage
  • Berkeley - I heard a slight rumbling noise, but nothing moved. I always look at my chandeliers to see them move, but they were still. It was just a few seconds.
  • Berkeley CA - Low rumble, just enough to wake me up around 3 am. No damage, no visible shaking, husband felt it too.
  • Berkeley - Was just a quick rattle. I happened to be awake. My girlfriend slept through it.
  • Oakland - Around 3am I heard a loud crash sound. I have not yet investigated any damage.
  • Oakland, CA - Very weak shaking
  • North Oakland - Felt the jolt & quick rumble, enough to wake me up. No damage.
  • Oakland - I heard a loud noise, the cat woke up, but I didn\'t feel any shaking.
  • Oakland - Woke up confused to a loud sound and rumble
  • Oakland, CA - Woke me and husband up. Quick, light shaking.
  • Oakland - Awoken by a short boom and shake very short
  • El Cerrito - It was enough to wake me up. It took me a bit to realize why I had awakened, it continued briefly after that. Rumble and shake, not a jolt or a roll.
  • Oakland - Thought it was part of my dream, so went back to sleep. Didn't realize it actually happened until a friend mentioned it later that day.
  • Pt. Richmond - Sudden jolt but passed quickly. I was awake in bed and felt the bed move. The rest of my household remained asleep. It was one of those deep jolts that suggest we might be on the verge of something.
  • Oakland - Weak shaking
  • El Cerrito - I was sitting at my desk working - heard a slight distant low, "boom" and the vibration and low bass that is common here with such events. Just a single shock; not even a jolt or any real movement, slight vibration. On a bed I may have heard it but probably not felt it (too much cushion). For reference the 6.x Napa quake didn't move us much either. Not sure what kind of ground we're on here but from experience I would have expected 2x the shaking then.
  • West Oakland - First felt a rumble/boom similar to a large truck heading to the Port of Oakland, but it was stronger than a truck rumble. After a brief pause there was a light rumble/shake for a couple seconds.
  • Berkeley - No damage. Felt like a strong ripple. Woke me.
  • Piedmont - A few seconds - woke me up.
  • Berkeley - Light shaking
  • Piedmont - A short, sharp juddering for less than one second. No damage. This type of earthquake - a sudden, brief jarring, or even just a thump - often happens here.
  • N. Berkeley - Light shaking
  • Oakland - Just about to fall asleep and I felt my wall shake. Thought somebody was stomping on the roof. My bedframe and the rocks on it shook. It was my first earthquake, and I didn't even realize what it was until my roommate told me the next day it was a quake.
  • Berkeley - Maybe 2 seconds, probably less. I was awake on Eastern time and in the bathroom-- been in NY for years, so was pleasantly surprised to be awake for a tiny tremor that caused no damage...(late report, back in NY with a computer and only now checked whether it was a real earthquake)...

    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.
