Here we go again: a 7.4 earthquake has struck Japan, just off the coast of the Miyagi prefecture. There is now a tsunami warning in effect for the country's northeastern coast, which is still recovering from last month's quakes and tsunami.
The current warning predicts a potential tsunami of as much as four feet.
The quake is only 73 miles from Fukushima, and it's being reported that buildings shook and windows broke as far away as Tokyo, which is 207 miles away. No word yet on how badly the melting nuclear reactors have been affected by this latest quake.
