During this period, no impulsive acoustic signals were recorded, unlike previous episodes characterized by small explosive events and rapidly returned to typical low levels.
Webcam images since 18 May indicated and later confirmed (on 27 May) water-filled 2019 Primary Crater vents. No ejected material is apparent about the crater. Several active steam and gas vents are now under water.
Thermal infrared measurements from observation flights also confirmed temperatures of the active vents are cooling significantly.
The volcano continues to produce weak to moderate gas-steam plumes that may caused weak acid rain downwind of the island as usual.
The Volcanic Alert Level remains at 1 and the Aviation Colour Code remains at Green.
