Yes, I had a very hard time going back in to get my things to move. I was lucky my friend who lived close by had water and electricity and my (ex) husband and I stayed with her for a bit. We actually went away for a week where we would not feel the aftershocks. I experienced the 71 Sylmar quake and it was NOTHING like Northridge. A lot of people moved away.
The website at
www.usgs.gov shows that he quake was not felt in Japan.
