You can move the map without zooming and the circles follow. I think the circles are quite proportional. I have a friend of a friend in Osaka who said they did feel the 9.0M one all the way down in Osaka so that circle is correct. Edit: Actually I had zoomed in a level. I think zooming in one level is a little more accurate. I really don't think people in Korea or Eastern Russia felt it.
