On Manam, in Papua New Guinea, the Deep Carbon observatory teams were able to measure the gases emitted by two summit volcano vents with a drone equipped with a MultiGAS, and send us this photo.

Partially cleared weather on the coast of Papua New Guinea has resulted in satellite images that confirm the emission of gas and ash from the Kadovar summit vent. The westward extension of the plume is however poorly defined because of the clouds present.

The eruption continues at Veniaminof, characterized by minor spattering and effusion of lava from the intracratal cone, confirmed by satellite temperature measurements.

Diffuse ash emissions have been observed on the webcam in previous days ... and traces of ash fall are possible on the surrounding communities depending on the wind conditions.

The aviation code remains orange, and the volcanic alert to Watch.
