October 8, 2021 — Kīlauea, Halema‘uma‘u Lava Lake Depth

The elevation profiles running East-West across Halema‘uma‘u crater show the rise of the lava lake surface during the ongoing eruption at the summit of Kīlauea. The lake lake is now about 260 m (850 feet) deep, and has risen nearly 30 m (98 feet) above the previous lake surface since the eruption began on September 29. More 15 million cubic meters of lava (4.2 billion gallons, or 6300 olympic size swimming pools) has erupted as of 8am on October 8. USGS graphic by B. Carr.
