Coming soon to the incredibly sinking city…

10 August 2007

On the other hand, subsidence has had a few positives lately, uncovering  Ahuizotl‘s tomb (one of my fave’s among Aztec notables — he banged his head swimming out of a flooded bathroom and spent his last few years in a coma… alas, allowing the not to swift Moctozuma II to take over) and the Temple at Iztapalapa recently.

Xinhuanet— An vast offshore tectonic plate that has reversed course and is sliding backward has geologists worried that a devastating earthquake may strike Mexico City.

The tectonic plate had been sliding toward Mexico City at a rate of 1 inch per year, as recorded by Global Positioning System measuring stations near Acapulco and Guerrero, which is about 175 miles southwest of Mexico City. That movement was normal, as predicted by theories of how Earth’s crustal plates should move.

At subduction zones, like this one, an oceanic plate usually slides beneath a continental plate, and now and then major temblors occur. Suddenly, in the latter half of 2006, the plate began moving the other way and quadrupled its speed, scientists announced today.
