The ongoing eruption at Kilauea summit continues to fill Halema‘uma‘u crater with lava. A gas plume rises from the active vent on the west (left) side of the crater as lava flows from the vent into the rising lava lake (black surface). An overflow onto the lowest visible down-dropped block on the east (right) of the lava lake occurred on Nov. 15. Above the block with the overflow, the edge of the largest down-dropped block stretches from bottom- to center-right. (USGS photo taken by N. Deligne on Nov. 16/Special to West Hawaii Today)
This plot shows the elevation of Halema‘uma‘u crater along a line running from west (left) to east (right). The pre-2018 collapse line (blue) shows the relatively shallow depth of Halema‘uma‘u during the lava lake period of 2008-18. The post-collapse (2019) elevation line is black, showing that 1,640 feet of collapse occurred during the 2018 eruption. The eruption which began in December 2020 created a lava lake that reached a depth of 740 feet by May (green line). The current eruption has caused the lake surface to rise another 200 feet and overflow a down-dropped block (red line). (USGS figure/Special to West Hawaii Today)
