In the middle of the image, the island that formed during the early phases of the eruption that began the evening of December 20, 2020, is visible; behind it, the west vent area is visible as a series of jagged peaks emitting volcanic gas. On July 18, a sulfur dioxide (SO2) emission rate of approximately 1,700 tonnes per day (t/d) was measured. USGS image by J. Chang.
