Popocatepetl, Location, Location, Location

The Popocatepetl volcano outside of Mexico City is not just spewing ash, it's making loud noises (loud enough to wake sleeping children in the middle of the night) and spewing burning rocks and lava (link here).  There's 20 million Mexicans in the possible ash / lava / devastation zone, but they don't want to evacuate and leave their homes.  Location, location, location.  Mt St Helen's ash cloud blanked under a million people.  Pompei was less than a million people (at the time).  Pinatubo affected 200,000 people.  Popocatepetl might be the biggest volcano of a lifetime...  ya veramos. 

If there are any Mexico City citizens who die from this eruption, it will be from their own choosing.  When the mountain shoots fire out of the top, move away, proactively, regardless of real estate interests.
