An earthquake with a magnitude of 5.5 on the Richter scale hit northern Japan today, rocking Fukushima-ken Oki and causing three strong aftershocks within an hour.
While there have been no reports of major damage or injuries, those affected were concerned about a possible tsunami warning; however, no warning has been issued. Residents are likely reminded of the devastating tsunami that tore through Japan in March of last year and swamped entire towns, leaving more than 28,000 people dead or missing.
The strongest shockwave had a magnitude of about 4.2. We will update this article with any changes.
