I'm here in Yokosuka Japan and that is exactly the way it felt! It wa super scary and we are still having aftershocks. We were VERY lucky not to have had the tsunami like our friends up north though. This whole country is in physical/psychological ruin :(
Mandy, I'll look up Yokosuka on a map in a minute! It's great to know that you are safe. Funny you mention the country in psychological ruin, it doesn't show in the videos, the culture has so much respect and honesty built into their morals that its surreal to not see people running around like jackasses looting, fighting, stealing, like would probably happen in the US if a coastal city was hit. I saw a video earlier of a train station, when the shaking began an attendant got on the loudspeaker and calmly started asking, yes ASKING that people kneel down to the ground in place, the doors to the trains were open, the ceiling in the station was dropping a piece here n there. NOBODY MOVED, everyone stayed in place as asked, no one went to save themselves, or made a dash for a train where a ceiling wouldn't collapse. When the shaking stopped, they stayed squatting in place, until the attendant got on the loudspeaker and informed them it was safe to stand and move about.
Other videos showed MILES of people standing in line for water, standing for days, in place, in a single file, at peace. Another, miles and miles of cars waiting for gas, not one horn, not one person thinking they are more important. May Japan be a model to the rest of the world on unity and morals, and make a prosperous recovery.
