Hi Petra - Yes I am familir with that link - I was just trying to point out that its also the same graph at the link I posted (from the documentation on the Mori site) - and there isn't any quake shown on the seismograph.

I think Roger was asking about motion represented - the site says this:
The full vertical range of the screen represents 0.0005 mm/s of ground motion.

Like I said - its just kind of a fun thing to look at - not really good to tell when there's a quake as it does have way too much motion and too short a window left to right.

The link below answers some questions.
