I tell you...untill you've been in one you just can't comprehend. I spent three and a half years in Japan and earth quakes were a weekly occurance. I was in some pretty bad ones too. Being from the mid north I never experienced an earth quake till then and it is something you can't forget. it just isn't a natural
feeling, very wierd infact.
Hope everything is ok brother...you live in a very unstable area and that's scary.
