Moderate but very shallow coastal earthquake in Japan
Felt in Tokyo (see below). JMA Japan reports a M4.7 Magnitude at a depth of 10 km below land.
Maximum intensity JMA 5- at Hitachi-shi Juocho-tomobe*
ER considers 5+ JMA as a potentially dangerous earthquake but considers this earthquake also as “to be followed up”.

 Very strong aftershock along the Alaska coast
Far enough out of the coast (epicenter area is the same location than the M7.5 of some weeks ago) to be harmless. Based on our visitor statistics we expect a lot of people to sleep through it in Juneau etc.
One of the stronger aftershocks so far.
Update 10:19 UTC : USGS has now released his report which is mentioning a Magnitude of 6.0 at a depth of 9.7 km, fairly close to the (mostly unpopulated) coast.
Although the expected shaking is VII MMI near the epicenter, nobody will feel it there. A max. light shaking has been reported by people so far. As we are curious how you have felt the shaking, please let us know by filling in the form below.

  • Petersburg, ak - Quick jolt like something hit the house
  • Terrace, bc - Only reason i noticed it was my decor clanking
  • Sitka, Alaska - Felt it and heard the house make a few cracking sounds.
  • Sitka Alaska - Felt ground shaking/rocking and heard windows rattle, but didn't last as long or shake household items like the one on the 5th did..
  • Edna Bay - Wakened from sound sleep by something (stronger shaking?) and felt shaking for a few seconds.
  • Edna Bay - Wakened from a sound sleep by loud roaring noise like a strong wind hitting the house. Once awake there was only a few seconds of moderate shaking of the house
  • Thorne Bay, Alaska - I was sitting on my couch watching a movie when I heard the kitchen cupboards shaking lightly. I realized it was an earthquake. I then noticed other things in the house shaking and swaying (2 inches either way). It seemed to slow down and then it picked up suddenly shaking harder than it did originally. It then trailed off to nothing. The whole thing lasted about 10 sec.

  • Vancouver, WA - Desk at which I was sitting began noticeably shaking...2nd storey floor was shaking as though people were running. Went outside to see if there were any visual indications...none.
  • Hockinson, WA - Sitting at kitchen table eating dinner and my chair felt jolted, the house shifted as if a MAC truck hit it, and heard the house creak and pantry rattle.
  • Washougal, Washington - It was pretty short. Not weak; short and sharp/rigid. It was not quite long enough for me to finish thinking What is this? It's an earthquake; is it gonna get worse, keep go... oh; it stopped.
  • Vancouver, WA - I just felt my whole room shaking. I was sitting on my bed and it started to shake.
  • Salmon Creek - Light shuttering lasted a few seconds
  • Vancouver, Washington - My 7 year old daughter and I looked at each bewildered as we tried to figure out what was happening-was it a diesel driving by? Did our basement just collapse? Before we could react-it was over, we were online instantly trying to confirm our suspicions.
  • Vancouver WA - I felt my whole house shake like something had hit it. The chair that I was sitting in rattled and moved for a second.

    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.

      My 8 year old daughter and I looked at each bewildered. Did a diesel just drive by? Did our basement just collapse? Before we could react or even figure out what was happening-it was over.
