A magnitude 6.8 earthquake jolted the disaster-affected prefectures of Miyagi and Fukushima in northeastern Japan on Friday afternoon. A tsunami advisory was issued, but was later lifted.
The Meteorological Agency says the quake struck at around 2:36 PM. Its focus was off Fukushima, at a depth of 20 kilometers.
Tremors with an intensity of 5 minus on the Japanese scale of zero to 7 were observed in Miyagi and Fukushima prefectures. Smaller tremors were felt in wide areas from northern to western Japan.
The agency withdrew a tsunami advisory issued to coastal areas of Miyagi and Fukushima about 40 minutes after the quake.
No abnormalities are reported at the Fukushima Daiichi nuclear power plant that was struck by the March 11th earthquake and tsunami.
Tokyo Electric Power Company says external power sources are intact and that radiation readings around the plant are showing no changes.
Sendai City in Miyagi Prefecture says one person suffered a light injury. Fukushima Prefecture says there have been no reports of damage or casualties.
The Meteorological Agency says the latest quake is likely to be an aftershock from March. It warns that more strong tremors are possible during active seismic periods that will likely recur in cycles.
Editor's Note: Apparently the quake has since been downgraded to a 6.3 according to reports by both the USGS and ESMC. Is there a scientific reason for this or is the reason more sinister as YouTube activist dutchsinse suggests? Refer to map below for quake location.
