The volcano Popocatépetl (known as "Popo" for short) has erupted numerous times over the centuries that records have been kept. There was a major eruption in 1947, but after that the volcano was mostly quiet for nearly a half century. Then in 1994 it came back to life spewing gas and ash and prompting the evacuation of nearby villages and the beginning of scientific monitoring of the peak. Over the past three decades Popo has been fuming and occasionally erupting. In 2000 there was another major eruption, and tens of thousands of people living close to the mountain were evacuated.
In the past few days, the volcano has once again become very active. There are some photos from the Mexican webcam site that I often look at. This webcam is situated at Tlamacas, the site of a mountain-climbers' lodge which was shut down after the peak was closed to climbing due to increased volcanic activity.
