True-color satellite image shows brown pumice rafts from an ongoing submarine volcanic eruption in the Central Bismarck Sea washing up on the shores of southern Manus Island (Papua New Guinea).
Satellite image of the Central Bismarck Sea (Papua new Guinea) showing an ongoing submarine volcanic eruption. Two white plumes of condensed water vapor emerge from the ocean surface above the eruption site, with currents of discolored cyan-to-green seawater and rafts of floating brown pumice flowing away in multiple directions.
A billowing cloud of steam produced by a submarine volcanic eruption rises above the ocean surface and drifts away into the distance. A plume of sediment in the water is also visible drifting downstream of the eruption.
Satellite image of a submarine volcanic eruption in the Bismarck Sea (Papua New Guinea), showing steam plumes rising from a raft of hot volcanic material on the sea surface, amidst meteorological clouds.
Cover page of the Hunga Atmospheric Impacts report, showing satellite images of the eruption plume.
Satellite image of sulfur dioxide (SO₂) column amounts in the atmosphere on November 24, after an eruption of Hayli Gubbi volcano in Ethiopia on November 23. SO₂ columns are depicted using a rainbow color scale ranging from white (low or zero SO₂) to red (high SO₂).
Map of column amounts of sulfur dioxide (SO2) gas in the Lewotobi volcanic plume, measured by the Sentinel-5P/TROPOMI satellite instrument. The map shows SO2 spreading west of the volcano in the upper troposphere.
Satellite imagery of nighttime lights shows darker regions of Spain and Portugal that were still affected by power outages overnight on April 28-29.
