There have been, at last count, more than 80 aftershocks in Japan. The Twitters have come fast, and a few translations are available via Global Voices. From @endamamicky: "Victim of tsunami here. Am at residence 2F with my mother, brother, and a neighbor waiting for rescue. No injuries. 1F is flooded and we can’t get out by ourselves. Also phone is not connected."
Chilling one from _mego, who is in Miyagi prefecture, the worst-hit city: “A tsunami just hit. I am taking pictures from the second floor of my house. The flooding continues and I am afraid of being left behind. Please come to my rescue!!”
