During recent summit deflation, the lava lake within HalemaÊ»umaÊ»u Crater dropped out of view of overlooks in HawaiÊ»i Volcanoes National Park. But since the switch to inflation early Sunday morning (September 18), KÄ«lauea Volcano’s summit lava lake has been rising again, bringing the lake surface back into view. This morning (Sept 20) the lake level was measured at 12 m (39 ft) below the vent rim, with sporadic spattering visible from the Park’s Jaggar Museum Overlook.
