Kilauea volcano (Hawai'i) activity update: lava lakes in Halema'uma'u and Pu'u O'o, lava flows on pali and coastal plain
Wed, 8 Aug 2012, 10:05
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. ...more [read all]

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 [read all]

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). ...more [read all]

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 [read all]

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 [read all]

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 [read all]

Following a week-long deflation, pressure returned to Kīlauea in full force, evidenced by an 8-microradian inflation at the summit! Correspondingly, the summit lava lake has returned to the previous record height of ~60m/200ft below Halema‘uma‘u crater floor, with exceptionally bright glow visible from the Jaggar Overlook over the past two nights! In the past, similar high lava stands have caused an increases in rim collapse and rarely, lava sprays visible from the museum! ...more [read all]

After a week-long deflation on Kīlauea, lava flows which had reached within 0.5mi/750m of the ocean finally felt the pressure relief and came to a pause. At the time of this writing there is still low pressure on the volcano, and the longer this continues the more likely that the plumbing system will be disrupted and that lava will re-emerge in a new location -- whether on a new point up the lava tube, or even all the way back to Pu`u `O`o crater on the east rift zone. Magma continues to come into the volcano, as evidenced by continued extension, and without an outlet, sooner or later something will have to give! While there is no red lava visible on the coast today, there is still bright glow from the newest summit vent in the National Park. This is a crucial period of change for the volcano, and we all await what will happen next!

Lava continues to flow on Kīlauea's coast, while its summit and rift zone continue to glow. Generally higher pressure over the past week, with fluctuations, has pushed new lava flows closer to the ocean than any time previously this year, but most are spreading out parallel to the coastline rather than directly to the ocean. Meanwhile, over the past week a new eastern flow branch developed above the pali and is now advancing down its steepest part, looking within reach of the coastal plain today. This eastern branch appears quite vigorous, and must be diverting a fair amount of lava from the flows near the coast. Stay tuned to find out if lava will reach the ocean for the first time in 2012 or if the volcano grows a new system of lava tubes or both!

Kīlauea's lava flows have surged in activity on the coastal plain accompanying inflation at the summit, though following by about 24 hours. This activity is farther from the ocean than before, relatively close to the base of the pali but moving quickly across cooling flows from the previous two months. Check out our new time-lapse movie showing the height of activity!
