The U.S. Geological Survey’s Hawaiian Volcano Observatory has captured remarkable video of lava bubbling near the surface at Kilauea volcano's summit.

The expanding vent of Halemaumau crater helps confirm scientists’ belief that the lava is close to the surface of the summit, said Janet Babb, a geologist and spokeswoman for the observatory.
Park rangers have begun keeping the overlook at the Jaggar Museum open later at night to accommodate the growing number of visitors arriving at dusk or after dark to view the glow.
Kilauea has been erupting for more than 25 years, with its lava creating a plume of steam as it spills into the Pacific Ocean.
But this recent activity is coming from the top of the volcano, not its sea-level side. This is the strongest glow coming from the crater since October, but scientists don’t know if lava will ever erupt in a fountain from within the crater, Babb said.
“There’s no way to know if that will ever materialize,” she said. “It would be grand to see some fountaining here.”
