Taiwan earthquake strong ground motion

I finally found the strong ground motion, here.

I just knew they put it out right away.

This is in velocity, although the scale reads 'acceleration'.  Who needs to worry about English over there?  :)

This is the beautiful clean plot near the epicentre on rock.  I am assuming this by the low value and short duration.  Max PGV of 5 cm/s .  It would be a lot of trouble to make sure this is hanging wall or footwall.

Farther away on soil we get 40 cm/s

This was my guess by the damage.  In Taiwan they have stated there should not be any structural damage until 50 cm/s and this is good target.  You can see that the solid buildings did well.  Tin can buildings fell, as well as soft storey buildings.  Inspection is everything!

In Chile, this made soft-storey condos lean over, and this has happened here as well.  For your homework kiddies, find the location of these sites, and see if there is a big difference between hanging and foot wall.  Also find the siting reports for these instruments.

Note: 40 in Chile for the main city.  80 right up next to the quake, and that made a solid building tip over in one piece.
