Effusive-explosive activity of the volcano continues at high levels during the past hours.

INSIVUMEH reported that the activity dramatically increases associated with lava flows, moderate strombolian explosions and constant incandescence from Mackenney summit crater.
Lava flows continue to be active on the northwestern slopes caused by eruptive fissure opened at the base of Mackenney cone, currently about 300 m long. New lava flows are expected on the northeastern and southwestern slopes. Elevated lava flows temperature could remain for several weeks or months.
Seismicity remains elevated including periods of high amplitude tremor associated with magma rising within the volcano.
Constant strombolian explosions caused partially collapse of the cone. Scoria is being ejected to an approximate height of 200 meters above the crater. Plume of ash rose to an altitude of 9,186 ft (2,800 m) and extending about 7 km to the southwest of the volcano.
In addition, fumarolic activity is observed and plumes were dispersed towards the W-NW direction.

Effusive-explosive activity of the volcano continues at high levels associated with lava flows in various directions and constant strombolian explosions in Mackenney summit crater. The same activity was recorded during 2006 and 2010, 2014 and during July-August 2019 as the magma was rising within the volcano through the eruptive fissures. Due to high level of activity it is expected higher effusion rate around the cone and explosions can become stronger. ... read all
