Whakaari/White Island (New Zealand) - Report for 28 April-4 May 2021

GeoNet reported that a brief period of low-energy tremor and acoustic signals was recorded at Whakaari/White Island beginning at 2230 on 29 April.
During an overflight on 30 April scientists did not observe new deposits near the active vent or thermal anomalies at the active vent area.
Gas-emission rates had been relatively unchanged since March.
The brief period of increased activity was likely caused by a series of low-energy subterranean explosions, similar to activity observed in mid-February and early-mid March.
Seismic tremor remained at background levels.
The Volcanic Alert Level remained at 1 and the Aviation Color Code remained at Green.
