The surprising threat from Mexico's awakened volcano - msnbc.com

All eyes continue to be on Popocatépetl and the volcano clearly still deserves the attention. Over the weekend, Popo produced at least 91 explosions over a 24 hour period. However, none of the events were larger than what we’ve been seeing over the last week. In fact, UNAM scientist Giovanni Sosa Ceballos says that we shouldn’t be expecting a large Plinian eruption from Popo as its recent volcanic history doesn’t favor such behavior. This doesn’t mean that the volcano isn’t still dangerous and doesn’t entirely rule out a large event. However, looking at the past activity at a volcano is one of the best ways to know what to expect in the present. The Mexican government still has people and resources ready for evacuations if the activity gets worse.
