The same general area of Japan that was devastated by an earthquake and tsunami almost exactly one year ago was rattled today by a 6.9 magnitude temblor that led authorities to warn of another possible tsunami along the nation's northeast coast. (Note at 7:42 a.m. ET: The U.S. Geological Survey had earlier estimated it was a 6.8-magnitude quake; we've updated our headline and post to reflect its new estimate.)
But just a short time ago, the Japan Meteorological Agency announced it had canceled "all tsunami warnings and advisories."
Still, the area was just shaken by another quake, this one a 6.1 magnitude. We'll watch for more news from there.
Update at 8:20 a.m. ET. Tokyo Shaken By New Quake:
The Japan Meteorological Agency says there was an estimated 6.1-magnitude quake near Tokyo just after 8 a.m. ET.
