During an overflight on 13 April, an explosion from Sangay volcano was observed at 08:25 local time. It generated an ash and steam column of 2 km above the summit crater.
A new vent was detected, both on visible and thermal images, located next to the active dome on the SE flank (Ñuñurqu). The activity in this area has intensified since October, when the last aerial survey had taken place.
Extensive lava flows are descending on the SE flank of the dome and reaching the base of the cone.
Strong fumarolic activity was seen on the SE flank of the dome and on the S flank of the central crater.
