Ah, ground-dancing ain't so bad...

I have been wanting for a long time to upload a movie of 2011 M9 earthquake. I found
just the right one recently, quite by accident, which is here.
https://www.youtube.com/watch?v=XqP-mar25a4This is probably the most compreheisive record of what it was like in the region up north. In
my area, which is Devon to London equivalent, I think, it was different. It was a lot milder and
the ground actually felt like slowly dancing below me.
It was a typical simple harmonic motion of perhaps 0.5 Hz and lasted for 5 minutes or so. Amplitude
felt like 30cm, and something like that is actually shown in the movie with gaping pavement.
We are currently expecting another big one like this. There is a local saying here which says that
at leats once in your life time you will experience a giant earthquake. My auntie who lives up north
in Sendai, close to the epicentre of this earthquake, has had 3 such experiencies already with her cats.
I have had one, but it may not be the last... P
