(BIVN) – Vigorous overflows from Kīlauea’s summit lava lake covered a large portion of the floor of Halema‘uma‘u this morning, and scientists with the USGS Hawaiian Volcano Observatory were able to capture the event on video during an overflight.

“In this video, the view starts from the north and heads south, showing the north and east sides of Halema‘uma‘u crater,” the USGS wrote about the footage. “During the overflight, a large overflow was active on the north margin of the lava lake, sending a cascade of lava down the elevated lake rim.”

The week of remarkable activity was summarized in this Volcano Activity Update issued on Thursday evening.
