The National Park Service is cautioning people to heed safety precautions while watching volcanic activity since the latest eruption of Hawaii's Kilauea volcano.

What had been low-level lava flows since Thursday morning became more vigorous fountaining Friday evening, according to the U.S. Geological Survey’s Hawaii Volcano Observatory.

The fountaining that drew thousands of views on the USGS YouTube page died down Christmas morning, according to Hawaiian Volcano Observatory, as Kilaueaʻs latest eruption pauses once again. The lava has been draining since the fountaining slowed and could be seen on the YouTube page.
