UPDATE: 10:10 am CDT (12:10 am Honshu): Fox has just said the USGS is reporting there were TWO 7.4 earthquakes, one after the other, at Honshu. [Original report] Some reports say the 7.4 magnitude quake hit the east coast of Japan within the last 15 minutes, another says within the last hour – at 9:50 am CDT it is 11:50 pm in Japan. Honshu is located in the same general area as the recent 9.4 Sendai earthquake. The quake is estimated to be 25 30.1 miles below sea level. A tsunami wave is estimated to be one meter high (3.28 feet). The reports are very early. Fox is just reporting that this 7.4 quake is the largest aftershock since the 9.4. I will have ongoing updates as available – see them below – the latest first.

Update April 8th 9:47 am CDT (11:47 pm Honshu): There are warnings that another “big aftershock” could hit the same region. Three fires were sparked from yesterdays 7.1 mag. quake and 13 gas leaks were reported in Sendai. The report linked below says the injured now numbers 250. Two to four are reported dead, but two are said not be as a result of the earthquake.
Some train services were suspended while about 8,300 houses were without water, and gas supplies were cut off in a wide area in Miyagi.
The quake had caused blackouts at as many as 4 million households and after recovery work more than 600,000 were still without electricity. Some mobile phone connections and landline phone services in north-eastern Japan were affected.
There was no impact reported at the stricken Fukushima Daiichi Nuclear Power Station, its operator, Tokyo Electric Power Co (TEPCO), said. The power station was crippled by the March 11 earthquake and subsequent tsunami.
Tohoku Electric Power Co, which runs Miyagi’s Onagawa Nuclear Power Plant, said water had spilled onto the floor at all three of the plant’s reactors, the public broadcaster NHK reported.
The company also said it found water leaks at eight locations in the plant, including inside buildings housing the reactors, NHK said.
The operator added that blowout panels, devices designed to control pressure inside the buildings, were damaged at a reactor turbine building, NHK said.
Update 10:53 pm CDT (April 8th 12:53 pm Honshu): Two people are confirmed dead, one a 79-year-old man (Miyagi) who died of shock, and a 63-year-old woman (Yamagata) whose oxygen machine failed in the power outage. Approximately 100 are injured.
Japan power said as of Friday, April 8th, 3.27 million buildings in 6 prefectures were without power following aftershock.
UPDATE: 10:15 pm CDT (12:15 am Honshu): The USGS is on Fox this minute saying THERE WAS ONLY ONE EARTHQUAKE/AFTERSHOCK, and the magnitude has been lowered to 7.1.
Also, an announcement has just been made that the men working inside the Fukushima reactor have not been affected by the new quake, and the site still has power. Now we wait to see if the Government is telling the truth.
UPDATE: 10:10 am CDT (12:10 am Honshu): Fox has just said the USGS is reporting there were TWO 7.4 earthquakes, one after the other, at Honshu.
UPDATE 10:oo am CDT – midnight in Honshu: Fox has a correspondent in Tokyo, saying people have lost power. In fact, they showed a satellite map of Japan and you can see the lights in the east coast area go out abruptly.
INTERESTING: This report says the US Geological Survey (USGS) reported last month that the force of the earlier 9.4 quake moved Japan’s main island by 2.4 meters or 7.87 feet.
