Most high rise buildings built within the last 20 years sit on rollers which are anchored deep into bedrock; the structure itself doesn't move much. Ground surface in the Valley of México is generally paved over mud (think Jello), but even the 70 year old
Latinoamericana Tower came thru the 8.1 quake in 1985 with no damage. It is very well anchored.
Using the SkyAlert app, the CDMX population gets an average 60 second warning from earthquakes occurring on the subduction zone 300 km away along the Pacific Coast. There is quite a bit that can be done in that time frame to prepare. There are now several apps applicable to USA states, but not yet advanced as Japan's or México's networks.
