I wasn't even born yet!
But I did read about it. Official papers read 4-5 thousand casualties, with something like thirty thousand injured .. Of course, I'm sure any number that can be presented wouldn't be completely correct, so there's absolutely no telling.
I also saw that a majority of the deaths were caused by the subpar construction of newer housing that put residents' safety second to the accomplishment of just COMPLETING said structures .. And that the earthquake caused the founding of an emergency system that will now alert Mexico City of the threat of an earthquake, minutes before it happens.
Apparently they're building another system nearby. It measures movement in the earth's crust underneath the water surrounding Mexico, so if there ever was the possibility of another tragedy, the people of Mexico City will have a better chance of surviving ..
It's sad that such things have to happen before we have a better way of coping with them.
What kinds of things does Mexico do to remember this day, Alex?
