The explosive eruption of the volcano continues characterized by vulcanian-type explosions and pyroclastic flows.
INSIVUMEH reported that seismic instruments recorded a moderate explosion at 07:15 local time yesterday producing large ash content to an altitude of 15,000 ft (4,600 m). The explosion generated a pumice-and-ash flows caused by eruption column collapse. These pyroclastic flows traveled over the Caliente dome slopes and formed phoenix clouds, as can be seen in the image. The pyroclastic flows reached the area of San Isidro river without affecting of inhabited area. Volcanic ash is dispersed towards the southwest and caused ash fall on the volcano's slopes.
