The sun angle was ideal this morning to show the complex texture on the surface of the lava lake in Halemaʻumaʻu Crater at Kīlauea's summit. Spattering was active in the southeast portion of the lake. For scale, the lake is about 230 meters or 755 feet across. Photo taken Wednesday, December 30, 2015 courtesy of USGS/HVO

A bubbling lava surface could be seen about 5 m (16 ft) below the opening of the new vent when viewed from the air. The size of the opening will likely grow with time, as the narrow septa between the individual holes collapse. Photo taken Thursday, December 17, 2015 courtesy of USGS/HVO

Lava, like this typical pāhoehoe flow on Nov. 12, 2015, continues to breakout northeast of Pu‘u ‘Ō‘ō (in background) on Kīlauea Volcano. Current activity is within about 6 km (4 mi) of the vent and poses no immediate threat to Puna communities. You can hear more about Kīlauea’s ongoing lava flow and other Hawaiian volcanoes during HVO’s Volcano Awareness Month talks in January 2016. Details posted at http://hvo.wr.usgs.gov USGS photo.

Volcano Watch: Volcano awareness: An important quest for Island of Hawai‘i residents

(Volcano Watch is a weekly article written by scientists at the U.S. Geological Survey’s Hawaiian Volcano Observatory.) This time last year, Kīlauea Volcano’s lava flow was threatening Pāhoa. Today, the immediate danger to Puna communities no longer exists, but lava continues to erupt from the Pu‘u ‘Ō‘ō vent. So, while the flow is largely out […]
