M 5.8      2012/02/29 14:32    Depth 20.0 km     JAPAN
local time 23:32 - Epicenter location see below in list
70 km SE Choshi (pop 75,650) and 108 km SE Narita (pop 100,641) (Narita is one of the Tokyo airports)
Earlier report we wrote when we found out the earthquake occurred
Preliminary data are talking about a strong earthquake 20 km out in the sea near Tokyo
We are estimating that the epicenter is about 50 km out in the sea. Certainly NOT strong enough to generate a tsunami.
JMA Japan reports a magnitude of 5.8 at a depth of 20 km. Max. registered intensity by JMA : 4 at Isumi-shi Misakicho-choja* - Earthquake-Report.com considers 5+ as dangerous for eventual damage
Conclusion Earthquake-Report.com : NOT dangerous for damage or injuries

  • Shinjuku, Tokyo - Woke up to the room swaying. 20-30 seconds.
  • Utsunomiya tochigi - We were here 3/11/11 in this same concrete third floor apartment. Our place is solid and we didn't have any damage even them. This morning at 7:30 AM 3/1/12, closet doors shaking - a little longer and louder than other tremors. Yesterday at 4:30 there was one too. Seem to be getting bigger and more frequent though I'd still say "tremors" vs. earthquakes as felt here.
  • Tokyo - Woke up shortly before earthquake exactly 8 hours after the earlier earthquake on the exact same 13th floor in Shinjuku hotel. This earthquake was shorter in duration but felt stronger than the one prior. ER : This is normal as the epicenter was below land and at an intermediate depth. The stronger M 5.8 earthquake had a max. intensity of 4 JMA, this one had an intensity of 5- JMA, that's only 1 marker below potentially dangerous for damage.
  • Tokyo - Suis pas une experte des tremblements, ça a vacillé un peu et duré
  • SINGAPORE - I felt the swaying as I was lying in bed in my hotel room on the 8th floor in Shinjuku. Heard sound of things knocking too. Lasted about 30 seconds.

  • Tokyo, Roppongi - Was in the bathtub and water began to sway quite strongly, strong enough to push me around. felt it or about 20 sec. 3rd floor of hotel.

    seismograph - recordingUseful information to read this daily earthquake list
    This earthquake list covers important earthquakes in the world.
    If a more detailed page is present, the earthquake line will be linked to the detailed page.
    For your comfort, we will provide in most cases a Google Satellite Map to give you an idea where the earthquake struck, which terrain it happened and if villages or cities are located in the immediate vicinity. The multi-source approach has been setup to compare values as seismology is not an exact science and needs a lot of calculations. The reference for the time zone is UTC (Coordinated Universal Time, also called GMT). Color explanation if we add some details above the list :
    green color = NOT dangerous for damage or injuries
    orange color = MODERATE risk for damage or injuries
    red color = CONSIDERABLE risk for damage or injuries

    QuakeSOS+ and QuakeSOS free are iPhone applications developed by Armand Vervaeck, the founder of Earthquake Report. The Application simplifies immediate group communication to friends and family members (with your exact GPS location) and is feeding the users with Earthquake Report news. The 0.99 US$ QuakeSOS+ version will support the activities of SOS Earthquakes.

    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.

    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.
