Gabriela HidalgoLike any strato-volcano Popocatepetl has the potential for a big explosive eruption. It also has the potential for a bunch of small eruptions then going back to sleep for a few tens of years. Because that second scenario is what Popocatepetl has done in the past then it is a much more likely scenario for the current unrest. For the eruption to be devastating in Mexico City the eruption would have to be huge, and I think it is very unlikely. The officials at UNAM have the best data and they know much more than I do about the activity of Popocatepetl.
Sincerely,
Scott Rowland
