Kilauea volcano (Hawai'i) activity update: lava lakes in Halema'uma'u and Pu'u O'o, lava flows on pali and coastal plain
Wednesday Aug 08, 2012 10:05 AM | BY: T
During 1-7 August HVO reported that the circulating lava lake periodically rose and fell in the deep pit within Kilauea's Halema'uma'u Crater. Measurements indicated that the gas plume from the vent continued to deposit variable amounts of spatter and Pele's hair onto nearby areas.
Glow from the lava pond in a small pit on the E edge of the Pu'u 'O'o crater floor and two vents along the S edge of the floor was visible with the web cameras.
Lava flows were active on the pali and the coastal plain.

Over the past two weeks, many DI pressure cycles have dominated the style of eruptive activity on Kīlauea volcano, influencing the location of coastal lava flows to be closer to the ocean or to the hillside with more and less pressure respectively. Active lava flows have been accessible over private land every day except one since our last update, and during higher pressure stands the activity has often put lava just inside the National Park boundary close to the ocean. During higher pressure days, lava flows often also break out on the lower part of the hillside and can be seen from a great distance from specific points within the National Park. ... [more]

Despite smaller-scale pressure cycles on Kīlauea volcano, recorded as a series of 1-2 microradian deflation-inflation events at the summit, lava levels have remained high with lots of activity for visitors to experience up close or from a distance! Glow visible from the Jaggar Overlook of the newest summit crater, the Overlook Vent, continues to be spectacularly bright during the evening hours, and lava flows continue to be active on the coast and are even visible from a distance on clear nights, better from the National Park side (as shown by the USGS Hōlei Pali Mobile Cam 4). ...

Over the past week and a half, lava flows on Kīlauea's coastal plain have persisted first through a low-pressure phase and now during a high-pressure phase, with the entire active flow-front advancing noticeably to with about 1km/0.5mi of the ocean. Compare today's image capture to our previous post to see this difference! ... [more]

Over the past week, lava flows on Kīlauea's coastal plain have been persistently advancing towards the ocean, though at a slower pace during a mid-week pressure decrease, increasing over the past day with renewed pressure. The flow front is estimated to be about 2km/1mi from the ocean still, so we await the effects of this renewed pressure at the coast! A series of webcam captures from the USGS-HVO shows the progression of these flows over the past week. ... [more]

During 30 May-5 June HVO reported that the circulating and spattering lava lake periodically rose and fell in the deep pit within Kilauea's Halema'uma'u Crater, rising as high as the inner ledge about 60 m below the crater floor. Periodic measurements indicated that the gas plume from the vent continued to deposit variable amounts of ash and Pele's hair onto nearby areas. The level of the lava pond in a small pit on the E edge of Pu'u 'O'o crater floor rose back into view. ... [more]
