i wonder how many buildings collapsed. it's not as if i expected them to be up to earthquake code in mexico d.f.

looks like 6-7 quake intensity in mexico city


I do a lot of work in Mexico, including tha D.F., and they do have seismic codes equal to the US. The '85 quake had a big impact on their building codes, and the quality of construction in the major cities has improved dramatically in the last 30-40 years. It's better than I saw in China and getting closer to US /Western Europe levels (not there yet).


well, you would know, i just picture it as

That's the sprawl where the common people live, they don't need no stinkin' codes.

Nuevo Polanco, however:

I've had a meeting in Torre Virreyes before, and I wonder how the ride was on the cantilevered side of the building during the quake.

You've never been in their traffic I take it? It can take you literally hours to get across the city if you go at the wrong time. All the big wigs use choppers to get around. Similar to Sao Paolo.

Just got off the phone with my partner and he was on the 19th floor of his hotel when it happened. High enough to really feel the building move. He was really impressed with how organized the hotel was with the evacuation and eventual re-habitation of the hotel. Clearly they had planned for this.

He's in the lobby right now waiting to get a new room lower down in the tower in case there are aftershocks.

Those videos are both awesome and frightening.

Watching something that large sway to and fro...jesus.

It's dual purpose of course. The other purpose is for evacuation/fire fighting for towers over a certain height. I don't recall what their requirement is but the towers in that pic are all close to 100m in height, which typically puts a building into the high-rise category for most international building codes.

A large volcano also is in the area. Popocatepetl, popo for short. Hope the quake don't spark that thing up.
