Roundup of Global Volcanic Activity:
Popocatépetl (Mexico): No significant changes in the currently low activity of the volcano have occurred recently. The volcano produces a small number (less than 10 usually) weak explosive emissions of steam, gas and sometimes ash on a daily basis, and magma continues to rise slowly to the summit where a lava dome forms. This is evidenced by glow at night, and was confirmed during a recent overfly with the support of the Mexican Navy.On the images obtained, one could see that a dome is slowly growing within the inner crater, partially filling it. Its diameter was estimated to about 200 m and it is about 50 meters below the average level of the floor of the main crater.The alert level of the volcano remains unchanged at Yellow phase 2
