Roundup of Global Volcanic Activity
Popocatépetl (Central Mexico): A series of small to moderate explosions occurred during 26-27 Dec at the volcano. The largest one, at 17:07 local time Friday, produced an ash plume that rose 3.5 km above the crater. Yesterday, CENAPRED recorded 6 explosions. Night-time incandescence is visible at the crater where a cake-like lava dome is growing, confirmed also during a recent overflight. This type of activity is still well within the normal range of the current state of semi-persistent mild activity at the volcano, and the alert level remains unchanged at “Yellow Phase 2”.
San Miguel (El Salvador): The volcano remains restless with seismic activity above background and shows occasional pulsating gas and steam emissions. Overall, activity has been slowly decreasing over the past months. Monday marks the anniversary of the strong explosion on 29 Dec 2013, when a large ash plume caused ash falls in Chinameca, New Guadalupe, Santiago de María, San Jorge and other areas near the volcano.
