It looks like it happened almost at the same spot as Mar. 11th's earthquake.
Japan's northeastern coast has been rattled by a strong aftershock.
The Japan meteorological agency has issued a tsunami warning for a wave of up to one meter. The warning was issued for a coastal area already ravaged by last month's tsunami.
Officials say the quake was a 7.4-magnitude and hit 25 miles (40 kilometers) under the water and off the coast of Miyagi prefecture. The quake that preceded last month's tsunami was a 9.0-magnitude.
Buildings as far away as Tokyo shook for about a minute.
A strong earthquake has occurred, but a tsunami IS NOT expected along the California, Oregon, Washington, British Columbia, or Alaska coast. NO tsunami warning, watch or advisory is in effect for these areas.
Based on the earthquake magnitude, location and historic tsunami records, a damaging tsunami IS NOT expected along the California, Oregon, Washington, British Columbia, and Alaska coasts. At coastal locations which have experienced strong ground shaking, local tsunamis are possible due to underwater landslides.
At 7:32 AM Pacific Daylight Time on April 7, an earthquake with preliminary magnitude 7.4 occurred near the east coast of Honshu, Japan . (Refer to the United States Geological Survey for official earthquake parameters.)
Pacific coastal regions outside California, Oregon, Washington, British Columbia, and Alaska should refer to the Pacific Tsunami Warning Center messages for information on the event.
This will be the only statement issued for this event by the West Coast/Alaska Tsunami Warning Center unless conditions warrant. See the WCATWC web site for basic tsunami information, safety rules, and a tsunami travel time map and table. (NOTE: Travel time maps and tables indicate forecasted times only, not that a wave was generated.)

Flash lights in the distance. (in Sendai)
Was it a comet???

OMG exactly the same thing happened here in Peru in the 2007 earthquake!!! people freaked out, thinking we where on an Alien invasion! It got almost no press, one friend saw this same type lights from the beach, she says she saw them coming from the sea horizon and also coming down from the sky. I saw them from the city, and I saw something shockingly similar to the video of lights in Sendai.

The only examples seen on youtube are indeed from big cities. I wonder if the same has been observed outside cities were no power lines are present.
Some luminous phenomena has also been reported to be the result of the stresses on certain rocks but i don't know if these flashes are part of them.

EGVG said:My friend was with her school mates and they all where on a trip to the south of lima, outside the city and they all saw this phenomena coming from the sky and from the sea into the air where it flashed very strongly! Same when I saw the lights they came from the sea area.

Interresting. It may suggest some sort of electrical discharges then.

Just wondering if anyone is aware if any serious investigation has been carried out on the possibility that earthquake lights are a discharge plasma generated through piezoelectric effect by earth stress events.
.The earthquake on February 27, did more than shake people up in the middle of the night. Reports have come in that mysterious lights also appeared around the quake’s epicentre near Market Rasen, Lincolnshire
One witness described how a grapefruit-sized glowing sphere appeared in her bedroom and then went out like a light. “This thing seemed to be coming across the room straight at me. I was very frightened,” she told the Louth Leader. Another person described flashes like car headlights at her window, and others spoke of lightning flashes after the quake. However, there was no lightning activity at the time of the quake.
In fact, there have been many reports of “earthquake lights” throughout history. Residents of Tangshan in China, for example, were awakened one night in July 1976 by bright flashes in the sky. Two days later an earthquake registering 7.8 on the Richter scale killed 240,000 people and destroyed the city. And a Japanese scientist took photographs of balls of light and red streaks in the sky during a swarm of earthquakes in Matsushiro between 1965 and 1967.
One explanation for his phenomenon is that the electrical properties of rocks may change under severe stress before or during a quake. This may generate changes in the electrical behaviour of the atmosphere, ionising the air and producing glowing lights.
Check out this story Ben, written by my oldest brother. It's a very real story about an earthquake which happened near the town where I lived when I was only 7 years old. Whilst the whole piece is quite entertaining, the most interesting part, and very relevant to your ponderings, is this bit:
Phil Smith's 'The Earthquake' wrote:
... I still couldn't figure out how a road that had been perfectly okay yesterday could have been so badly damaged by this morning. As I stood there wondering about this, there was a very deep and dreadful roaring sound which came from beneath my feet and the ground started to rock and shiver just as it had during Saturday night's earthquake. This was accompanied by flashes like lightning from the broken ground where the road had collapsed. To this day I am still not sure about this ... was my mind playing some sort of tricks on me to get me out of there, or did these flashes really happen? As rocks and stones started to tumble down the mountainside and land all around me, I leapt back on the Triumph, spun it around, and headed off flat-out down the hill to get clear of the mountain. Later that day, when scientists arrived to invesigate the earthquakes, I learned that there had indeed been two periods of aftershock activity recorded that morning and the first of these must have caused my "moving humps" which I saw near Boolara and the landslide which had taken the foundations out from underneath the road where I had had my roller coaster ride, and the second had caused the dreadful noise and rockfall which occurred while I was standing looking at the damage caused by the first one. ...

But some of the radiation readings at Reactors Nos. 1 and 3 over the last week were nearly as high as or higher than the 3,300 rems per hour that the commission said it was trying to explain, so it would appear that the speculation would apply to them as well. At No. 2, extremely radioactive material continues to ooze out of the reactor pressure vessel, and the leak is likely to widen with time, a western nuclear executive asserted.
“It’s a little like pulling a thread out of your tie,” said the executive, who spoke on the condition of anonymity to protect business connections in Japan. “Any breach gets bigger.”
Flashes of extremely intense radioactivity have become a serious problem, he said. Tokyo Electric’s difficulties in providing accurate information on radiation are not a result of software problems, as some Japanese officials have suggested, but stem from damage to measurement instruments caused by radiation, the executive said.
