M 5.5      2011/02/16 23:45    Depth 30.0 km     RYUKYU ISLANDS, JAPAN
local time 08:45
UPDATE 17/02 - 00:34 UTC : Earthquakes are being felt differently most of the time. A similar earthquake at an even bigger distance from Okinawa on February 15 had a bigger shaking impact than the present one.

UPDATE 17/02 - 00:23 UTC : JMA reports a magnitude of 5.2 at a depth of 10 km.  The earthquake Felt reports arriving at JMA are giving a JMA value of 2 = III MMI for the southern Okinawa Prefecture and a 1 JMA = 2 MMI for the northern part.
Because of the limited magnitude, a tsunami was immediately excluded.

UPDATE 17/02 - 00:18 UTC :
First felt reports out of Naha are giving a MMI value of II to III = weak shaking, probably caused by the very shallow hypocenter. In such cases the shaking will be very strong just above the epicenter and a lot less 50 km away.

Strong earthquake relatively close to  Okinawa.

UPDATE 19:44 UTC : Although the reported magnitude is rather limited, Earthquake-Report calls this earthquake moderately dangerous. The area is quiet unstable the last couple of weeks and the cities described below are close to the epicenter (if confirmed). It will take a number of hours to find out if everything is OK.

Shallow moderate earthquake close to Farkar and Taloqan.

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 Google Satellite Map links 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 reference for the time zone is UTC (Coordinated Universal Time, also called GMT)
The page is regularly updated to add new earthquakes.
green color = NOT dangerous for damage or injuries
orange color = MODERATE risk for damage or injuries
red color = CONSIDERABLE risk for damage or injuries

  1. Arisa Asrul says:

    i have question, when earthquake happened, mainshock always be occured at the first time?

    • Armand Vervaeck says:

      Normally Yes

    • In many cases there are a lot smaller magnitude earthquakes in the preceding days months or even years for a main shock, which can be tracked to the mainshock.
      Essentiallly the mainshock usually occurs and then an aftershock sequence.
      But in some cases like the Tongan trench, you get many earthquakes of similar magnitudes as similar size mainshocks.
      In other cases you may get a foreshock and then mainshock. Sometimes just the mainshock. It is very variable!

  2. Arisa Asrul says:

    Since 12pm (indonesian timezone), there a few small shake in sorowako, when i write this a minute ago i felt a a small shake, do you have any information about, several people still live in open area because they got rumor about middle of the night will occure a big earthquake.

    • Armand Vervaeck says:

      Rumors on a big coming earthquake are ridiculous. Earthquakes are UNPREDICTABLE.
      Of course, after an earthquake like yesterday, a lot of aftershocks can scare people a lot. Most of the time aftershocks are always smaller than the mainshock, however even that cannot be predicted. In some cases they can indeed be stronger, but nobody can predict that. BMKG, USGS, EMSC etc, the biggest organizations in the world cannot predict the magnitude of an upcoming earthquake.
      The current aftershocks may go on for days, weeks and even months, but normally the frequency will go down and the magnitude in average also. Some major aftershocks are still possible. The February 27 2010 massive earthquake in Chile still generates aftershocks today.

    • Arisa Asrul says:

      There a middle shake at 12:43 am 17 february 2011 in sorowako about 2-3 second, unpredictable

    • Armand Vervaeck says:

      Thanks for reporting Arisa.
      The aftershock is a magnitude 4.7 (yesterday it was 6.1) at a depth of 33 km (deeper than yesterday).
      Can you please continue reporting below the following page :
