Did it's job properly. Putting a big mass up there to slow down the shaking of the building, plus sloshing around and absorbing oodles of energy.

It would be interesting to compare their building codes with those from other seismic areas, those tower blocks leaning over at 20 degrees are most impressive.

Yes. Impressive in their construction codes, not so impressive in their geotechnical skills.

"Most likely no liquefaction involved, but rather typical soft story failure. I'm guessing that the ground floors were commercial. Corner columns were knocked out, and the box above rotated. Buildings of 4-10 stories are more susceptible to this type failure than shorter or taller buildings." said an engineer.

So not geo, just poorly braced car parking levels etc.

Ehhh... Most Geotechs I know are also into the whole "ensuring structural integrity during earthquakes" thing. Or at least the ones I worked with during my decade doing geotech.

However, I am willing to stipulate that the company I worked for was not the typical company, and may have exercised care "differently" than others.
