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”.

Japan Hitachi January 31 2013 earthquake

 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.

Alaska / British Columbia aftershock January 31 2013

Earthquake near Lata, Santa Cruz Islands
(M 6.2) Another strong earthquake with magnitude greater than yesterday. Epicenter located 65 km E Lata (pop 538). We categorize it as a harmless earthquake since populated residential areas are 1000+ km far from the epicenter.
No Tsunami expected.

  • 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.

    Useful 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. 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

    MMI VII (Very strong shaking) ?
    People
    General alarm. Difficulty experienced in standing. Noticed by motorcar drivers who may stop.
    Fittings :

    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.
