Very strong earthquake off East Coast of Honshu, Japan + dangerous 5.8 aftershock only survives with (mostly small) PRIVATE DONATIONS. Your gift will be highly appreciated.

Update : The 5.8 aftershock near the coast was far more dangerous (due to the shaking danger) than the earlier M6.9 mainshock. JMA reported a 5+ intensity which is seen by Earthquake-report as potentially dangerous for damage.
JMA 5+    Hashikami-cho Dobutsu*
JMA 4    Hachinohe-shi Uchimaru*,  Hachinohe-shi Nangoku*, Sannohe-machi Zaifu-kojimachi*, Aomori Nambu-cho Tomabechi*, Aomori Nambu-cho Taira*
JMA5+ means :
* Many people find it difficult to walk without holding onto  something stable
* Dishes in cupboards and items on bookshelves are more likely to fall
* Unsecured furniture may topple over
* Unreinforced concrete-block walls may collapse

Update 23:50 UTC : JMA message : <Tsunami Advisory> Marine threat is in place, Get out of the water and leave the coast immediately. As the strong current will continue, do not get in the sea or approach coasts until the advisory is cleared.
<Tsunami Forecast (Slight Sea Level Change)>
Though there may be slight sea-level change in coastal regions, no tsunami damage is expected.

Update : A Tsunami advisory has been called for the coastal area of the Iwate prefecture. The expected waves do range from 0.2 to 1 meter maximum

Update : Max shaking intensity is 4 at Gonohe-machi Furudate and Aomori Nambu-cho Taira* Based on our experience with Japanese earthquakes, considers JMA 5+ intensity as a potentially dangerous shaking.

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.
