A relatively significant change in the activity of the volcano has occurred. As the effusive-explosive eruption has been dramatically increasing during the past 2 months, a weak strombolian activity continues from the Mackenney summit crater last days.

INSIVUMEH reported that no lava flows are being observed, but their absence has not been decreasing the seismic activity. Formation of lava flows in the near future is a possibility if activity at the volcano increases.
A satellite image from 23 July shows that the thermal anomaly is being observed on the northwestern slopes where the lava flows have continued to be active.
Strombolian activity continues from the Mackenney summit crater with ejecta thrown at an approximate height of 200 meters and 50 m away from the crater.
Incandescence continues to be observed in the crater.
Fluctuating seismicity continues with periods of high amplitude tremor associated with magma rising within the volcano.

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
