Mary of course is correct. But, I did see images of an eruption on CNN television news last night...they just called the volcano something like Mexico's mountain of fire (is that what Popocatapetl means?). Since I was not sure what volcano this was, I just tried Google on mountain of fire...and then was fooled....
So, I think it is erupting now, but for all I know CNN pulled out old footage because they were bored..
