re: #137 Dr Lizardo

What makes quakes in Mexico City so damaging is that the land that Mexico City rests upon is not bedrock, but land that is far more susceptible to motion and liquefaction/subsidence.

The damage is going to be pretty bad, but after the 1985 quake, Mexico instituted rigorous seismic building codes, and newer buildings should do better. It’s the older ones you have to worry about - as well as those buildings that are adjacent to older structures.

If you have buildings swaying at different frequencies due to their height/size, they could damage each other in the process.

Mexico’s going to need lots of help, and Trump is going to prattle on about building a fucking wall. There isn’t a shred of decency in him or his admin (or the GOP at large, because they elected this sociopath).
