The continuing low-level effusive-explosive activity of the volcano started to decrease gradually and it seems to have paused as the Alaska Volcano Observatory (AVO) noted. Therefore the Aviation Color Code for the volcano was lowered to „yellow“ and the Volcano Alert Level to „advisory“.

No evidence of an ash and steam emissions was detected on 1 April.

The elevated surface temperatures continue to be detected in the satellite images from 31 March due to heat releasing from the cooling lava flows.

The seismic instruments recorded no significant seismic activity during the past days.

Pauses in explosive activity are common and lava flows and eruption of minor ash plumes could resume suddenly with little or no warning.
