Kilauea volcano (Hawai'i): activity summary 28 Nov - 4 Dec 2012
Wednesday Dec 05, 2012 11:05 AM | BY: T
During 28 November-4 December HVO reported that on most days the circulating lava lake periodically rose and fell in the deep pit within Kilauea's Halema'uma'u Crater. Occasional measurements indicated that the gas plume from the vent continued to deposit variable amounts of ash, spatter, and Pele's hair onto nearby areas.
At Pu'u 'O'o Crater, lava circulated within the perched lava lake at the NE part of the crater, and glow emanated from spatter cones on the SE part of the crater floor and from a spatter cone at the NW edge. Lava overflowed the lava lake on 24 November and 2 December.
Lava flows remained active in two branches on the coastal plain: a small W branch, and a larger E branch with scattered activity extending from the pali to the coast E of the easternmost boundary of Hawai'i Volcanoes National Park. During 28-30 November steam plumes did not rise from the ocean entry point; on 30 November geologists confirmed that active lava flows were 100 m from the coast. Lava again entered the ocean during 1-2 and 4 December.
