Stromboli (Eolian Islands, Italy): Volcanic tremor has increased during the past 24 hours, but is back to lower values at the moment. All in all, activity levels is elevated, and the magma column inside the conduit is standing high.
Batu Tara (Sunda Islands, Indonesia): An explosion produced an ash plume rising to 8,000 ft (2.4 km) altitude this morning, VAAC Darwin reported.
Popocatépetl (Central Mexico): Ash emissions continue. A plume rises to at about 27,000 ft (7 km) altitude (or approx. 1500 m above the crater) and drifts east.
The seismic signal shows numerous volcanic quakes, but less tremor. Glow can be seen on webcam images.
Santa María / Santiaguito (Guatemala): Activity remains similar to before. Moderate explosions from time to time produce ash plumes rising about 700 m altitude.
Light ash fall was reported yesterday in Calahuaché. Effusive activity has been low at the lava flows on the dome's flanks.
