  7th Anniversary of Kīlauea Volcano's Summit Eruption


An aerial view into Kīlauea Volcano’s summit vent within Halemaʻumaʻu Crater on March 10, 2015. The lava lake level on this day was 57 m (187 ft) below the vent rim. The lava lake level has fluctuated several tens of meters (yards) over the past few months, as indicated by the black “bathtub ring” on the “Overlook crater” walls, which indicates a former higher level of lava within the vent.

        On March 19, 2008, an explosive eruption—the first at Kīlauea’s summit since 1924—blasted fragments of hot rock from Halemaʻumaʻu Crater, forming a gaping hole (vent) about 35 m (115 ft) wide at the base of the south crater wall, just below the former visitor overlook. This event marked the beginning of Kīlauea Volcano’s most recent—and ongoing—summit eruption.
        Over the past 7 years, the vent (informally called the “Overlook crater”) within Halemaʻumaʻu Crater has enlarged to about 160 m by 200 m (525 ft by 655 ft). The active lake of lava within the vent produces an impressive nighttime glow, but also continuously emits sulfur dioxide gas that results in “vog” (volcanic smog) that can impact downwind communities.
        USGS-HVO scientists are monitoring the lake level fluctuations, gas emissions, and other parameters to study how lava lakes form and evolve and what the summit activity might reveal about Kīlauea Volcano’s plumbing system.
        The first five years of Kīlauea's summit eruption in Halemaʻumaʻu Crater, 2008-2013, a USGS Fact Sheet published in 2013, includes an eruption chronology and overview of lava lake activity and Overlook crater growth from 2008 to 2013.
