Overflows from the perched lava pond within west pit, a small crater adjacent to the main Pu‘u ‘Ō‘ō crater on Kīlauea Volcano’s East Rift Zone, continue to build up the levees around the pond. The rising level of the perched lava pond during the past month is a sign of the increasing pressure within the magma system beneath Pu‘u ‘Ō‘ō. This overflow, captured by a USGS-Hawaiian Volcano Observatory time-lapse camera, occurred on April 17, 2018. Photo taken Tuesday, April 17, 2018 courtesy of U.S. Geological Survey

Wednesday (February 22, 2017), the breakout along the eastern edge of Kīlauea Volcano's episode 61g flow remains active and had advanced approximately 570 m (620 yards) since it was last mapped on February 14. The flow front consisted of sluggish, oozing pāhoehoe that was approximately 730 m (0.5 miles) from the ocean and 540 m (0.3 miles) from the emergency route road. Channelized lava flows have been recently reported on Pūlama pali, but no active channels were seen by HVO geologists while working in the area this afternoon. They did, however, observe scattered breakouts on the pali. Photo taken Wednesday, February 22, 2017 courtesy of USGS/HVO
