Aerial Video of Kīlauea Volcano’s Summit Lava Lake

This aerial video footage, filmed by USGS in late July 2016, features Kīlauea Volcano’s summit vent within Halemaʻumaʻu Crater.

Hawaiʻi Volcanoes National Park’s Jaggar Museum, and the adjacent USGS Hawaiian Volcano Observatory, are perched on the rim of Kīlauea’s summit caldera (foreground of opening footage) just over a mile from the crater, offering spectacular viewing opportunities for Park visitors. Closer to Halemaʻumaʻu, black lava flows on both sides of the summit vent are clearly visible; these flows spilled onto the crater floor when the lava lake overflowed the vent rim in April–May 2015.

At the time this footage was captured, the lava lake level was 22–26 m (72–85 ft) below the vent rim; this morning, it was about 32 m (105 ft) below the vent rim. The summit vent, initially 35 m (115 ft) wide when it first opened in March 2008, has since been enlarged by numerous vent rim collapses and is now about 180 by 250 meters (590 by 820 feet) across.
