Activity at Puu Oo crater received much attention in recent weeks as lava from multiple vents regularly began sending out small flows virtually covering the crater floor. The Puu Oo vent has been erupting continuously since January 1983, over the years producing much of the lava flows that have blanketed areas downslope of the eruption site, including the residential area of Kalapana and Royal Gardens, and vast sections of the Puna coastline.
Activity at Kilauea volcano’s summit Halemaumau crater, meanwhile, drew attention in February for a series of rock collapses, earthquakes and a rising lava lake below the surface of that crater’s floor. HVO geologists reported lava levels at the lake receding rapidly on Saturday afternoon and evening as the summit continued to deflate, possibly due to increased activity at Puu Oo.
Halemaumau crater has been producing a steam and ash plume from an ever-expanding vent in its floor since March 2008. Six months later, Hawaiian Volcano Observatory geologists discovered a lava lake roiling within the vent, deep below the surface of the Halemaumau crater floor.
The new active fissure between Puu Oo and Napau craters is located in a remote area of Hawaii Volcanoes National Park, now closed to the public.
Hawaiian Volcano Observatory geologists on Sunday set up a webcam offering live views of the new fissure eruption, refreshed every five minutes.
Access to Puu Oo is off limits to hikers. But activity at Halemaumau crater is visible to Hawaii Volcanoes National Park visitors from the Hawaiian Volcano Observatory’s Thomas A. Jaggar Museum overlook, which is open 24 hours daily. Daily updates on Kilauea volcano activity are available at the Hawaiian Volcano Observatory website.
