A bright thermal anomaly is noting over the volcano. Probably an extrude of lava blocks at the top of the dome continues, that prepares a strong explosive eruption of the volcano. \n\nStrong ash explosions up to 49,200 ft (15 km) a.s.l. could occur at any time during this day or next days. Ongoing activity could affect international and low-flying aircraft.
