Whakaari/White Island volcano (North Island, New Zealand) - Smithsonian / USGS Weekly Volcanic Activity Report for 11 November-17 November 2020 (New Activity / Unrest)

Following a period of severe weather, on 11 November GeoNet reported some mainland observations of darker plumes and deposits on webcams; scientists conducted an overflight of Whakaari/White Island on 12 November to investigate. Aerial observations confirmed the presence of ash in the emissions, originating from the main steam vent at the back of the crater lake. An initial analysis indicated that the ash was from loose material around the vent being entrained into the gas-and-steam plumes. ... Read all

On 16 June GeoNet reported that during the previous few months activity levels at Whakaari/White Island had gradually progressed on a downward trend based on the volcano monitoring team's collective interpretation of all the monitoring data. Temperatures at the gas vents remained high (over 450 degrees Celsius) though a slow decline in heat input from depth has been recorded. Although magma remained at a shallow depth, an estimated 1 km below the surface, gas discharge and ground deformation were not increasing. ... Read all
