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.
49 km SE Haebaru (pop 34,239) and 55 km SE Urasoe (pop 110,282)

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

QuakeSOS+ is an iPhone application developed by Armand Vervaeck, the creator and main contributor to Earthquake Report. The Application simplifies immediate group communication to friends and family members (with your exact GPS location) and is constantly feeding the users with œEarthquake Report news. Together with your own family and friends, QuakeSOS+ will be your closest earthquake friend. Buying QuakeSOS+ will support the activities of SOS Earthquakes.

a was also created by SOS Earthquakes. makes it easy to let the world know which shaking people have experienced during the earthquake. gives also the opportunity to write some additional text. Filling up the form takes only 1 minute. gives an overview of all the resent earthquakes and let you even go back in time and retrieve earthquakes of a certain date in the past. headlines on twitter

  1. On the early afternoon of 2-17-2011 I felt a strong vibration. The last time I experienced this was when there was a rare quake in the Gulf of Mexico and I felt that as well. I live in Central Florida area. Now 5 days after I felt the vibration on 2-17 there has been an earthquake in New Zealand. Also, it seems strange that everytime there is an earthquake on one side of the planet a few days later there will be one on the other side of the planet. Why is that? Does anyone else notice this? I have been aware of this for years and yet no one seems to ever say anything about it.

    • Yes, I do. These earthquakes correlate to Moon Perigee---when the moon is closest to earth. Check out moon perigee calculater. Next month will be even bigger events: the moon will be closest on the 17th of march; this perigee just past, caused the New Zealand quake and caused a swarm to happen in Arkansas, as wells as a swarm in Yellowstone park; last year it caused the Hatii quake and Chile. Earthquakes by Japan seem to predate quakes across the pacific. Check out the Usa map--google usa earthquakes to watch them happen--use animation on the map and watch earthquakes over a seven-day period; google earthquakes on Feb. 18 2011 to see there were other events---the same day as the Full moon.

    • Hi Swayze,
      There are many other systems at play.... but it is always interesting to find trends in things. The fact is that there are many earthquakes at ALL periods of the moon cycle in terms of magnitude, strength, death toll, size, economic loss etc. etc.
      The moon does not cause earthquakes, but the gravitational pull etc. could PERHAPS be one factor.

      More interesting still is the fact that before many earthquakes, the number of cats and dogs that go missing is greater etc. etc., radon gas levels occasionally increase etc etc. But never for all earthquakes!
      Earthquake prediction is difficult and there will always be errors. Just like estimating death tolls and economic losses. is more interested in the tangible effects of earthquakes, but thanks for the input.
