Kīlauea summit eruption - September 10, 2023

A line of vigorously fountaining vents was visible on the floor of the downdropped block within Kīlauea caldera during the afternoon of September 10, 2023. This image, taken from near the Uēkahuna overlook, shows the activity extending east of Halemaʻumaʻu crater and onto the downdropped block. The scarp of the downdropped block, which formed during the 2018 summit collapse, is visible in the background of the image. USGS image by M. Patrick.
