A Japan earthquake today has struck early Saturday at the area where a deadly tremor struck almost three years ago. A tsunami warning was issued following the Japan earthquake today but the tsunami never materialized, CNN has learned.

A region in Japan has been struck by a powerful earthquake today. The said area suffered devastating events three years ago including a fatal tremor, nuclear crisis and tsunami.

According to the Japan Meteorological Agency a tsunami warning has been issued after the Japan earthquake today to ensure that the residents of the area will engage into precautionary measures.

The warning was later amended to advisories in certain areas where the Japan earthquake today struck such as Iwate, Fukushima and Miyagi prefectures. Fukushima is the site of the Fukushima Daiichi nuclear power facility, which was reportedly the center of a weeks-long radioactive crisis.

Nevertheless, at around 6:15 a.m. after the Japan earthquake today happened, the agency noted that all tsunami advisories be canceled.

While the previous announcement asked residents to "get out of the water and leave the coast immediately," the new one is less alarming. "Pay attention when fishing, swimming or engaging in other activities, as there may still be slight sea-level changes for the time being," the agency's new announcement says.

Reports said the Japan earthquake today was characterized as a 6.8 magnitude quake as per the Japan Meteorological Agency's statement, but the U.S. Geological Survey downgraded the quake to a 6.5 magnitude tremor.

The USGS said that the Japan earthquake today centered off Honshu island some 129 kilometers east-southeast of Namie and 284 kilometers east-northeast of Tokyo and it was 11 kilometers deep.

On March 11, 2011, a magnitude 9.0 earthquake struck Japan and caused devastating tsunami afterwards, leaving over 15,000 people dead and over 3,200 missing.
