Lava lakes at Kilauea seethe and bubble (and the UK media gets in a muddle) 10 June 2011

Halema'uma'u Crater lava lake, 2 June 2011: screen capture from Hawaiian Volcano Observatory video (USGS/HVO)

There are currently two active lava lakes at Kilauea volcano on Hawaii, one at the summit in Halema’uma’u Crater and one on the floor of Pu’u O’o Crater in the East Rift Zone of the volcano, about 25 km ESE of the summit. The Halema’uma’u lava lake has been particularly active since late May, with a rather spectacular lava flow feeding directly into the lake. This makes for some absolutely stunning images – when effusive basaltic volcanoes are in this mood, they can rival in their own way the visual drama of their more explosive silicic cousins. The Hawaiian Volcano Observatory have released a video taken on 1 June of the activity at the Halema’uma’u lava lake: the screen captures above and below come from this video (click here for the HVO page hosting the video, or here for a direct link to the .mov file).

Lava lakes are not unknown at Kilauea: a celebrated one existed for decades at the summit of the volcano, a favourite of visiting volcano artists, until it vanished during the eruption of 1924. The lava lake re-emerged at Halema’uma’u in September 2008 and has been there ever since, at varying levels and with periods of replenishment and circulation alternating with periods in which the lake has been static and crusted over. The Halema’uma’u lava lake has been formed by lava feeding into an existing crater and and forming a pond within it; the lake at Pu’u O’o is of a different type known as a perched lava lake or lava pond, where lava has been erupted from a vent or fissure and has become contained not by an existing topographic feature but within walls created by the cooling of its own margins.

The Smithsonian Institution and United States Geological Survey Weekly Volcanic Activity Report, compiled by Sally Kuhn Sennert, has been issued for the week 1-7 June 2011. It’s been a lively volcanic week – highlights include:

  • Dieng Volcanic Complex: carbon dioxide emissions and seismicity both remain elevated
  • Popocatépetl: ash plumes reaching altitudes between 1 and 3 km create ashfall in nearby regions
  • Puyehue-Cordón Caulle: an eruption began on 4 June following intense seismicity
  • Kilaeua: two lava lakes were active during 1-7 June

The Smithsonian Institution and United States Geological Survey Weekly Volcanic Activity Report has been issued for the week 25-31 May 2011. The report is compiled by Sally Kuhn Sennert. Notable volcanic events this week include:

  • Dieng Volcanic Complex: evacuations following increase in gas emissions and seismic activity
  • Grímsvötn: an eruption characterized by explosive activity and ash plumes, with limited ashfall
  • Kilauea: the level of the Pu’u’O’o lava lake continued to fluctuate
  • Taal: water temperature, acidity and water level all rose in Taal’s Main Crater Lake, and there was an increase in seismic activity

Here is the Weekly Volcanic Activity Report covering 5 to 11 January 2010, issued by the Smithsonian Institution and United States Geological Survey and compiled by Sally Kuhn Sennert. Some selected highlights:

  • Etna: still restless, with weak emissions, strombolian activity and degassing
  • Kizimen: eruptive activity continues with continuous emissions to 6-8 km a.s.l. and ashfall
  • Fuego: explosions, incandescence, ash plumes and ashfall
  • Merapi: lahars cause floods and damage on Merapi’s flanks

The maps accompanying this report will be available shortly – apologies for the delay.
