On March 19, 2008, a new volcanic vent opened in Halema‘uma‘u Crater at Kīlauea’s summit. Nine years later, the eruption continues. The vent has grown to a gaping crater that’s roughly 195 m by 255 m (about 640 x 840 ft) in size. A lava lake within the vent rises and falls, with spattering on the lake surface sometimes visible from the Jaggar Museum Observation Deck. USGS Hawaiian Volcano Observatory geologist Matt Patrick presents an update and overview on the summit eruption, including stunning imagery.
