 Kilauea volcano (Hawaii), news: new gas vent in Halemau'uma'u cratermardi mars 18, 2008 01:47 |
While lava continues to flow into the ocean, an unusual event is taking place at the summit of the volcano: a new gas vent has opened at the base of Halemaumau crater in the caldera of Kilauea volcano. Here is some additional information released by HVO: A prominent new gas vent broke through the lower east wall of Halema`uma`u crater on March 12, 2008, doubling the already elevated level of sulfur dioxide gas being emitted from the crater. The vent was obviously incandescent by evening of the next day. Release of sulfur dioxide gas from Kilauea volcano is not new, but the current emission rates are unusual. Gas emissions have been unsettled since June 2007 but the root cause of the recent increase in SO2 emissions from Halema`uma`u crater is not yet clear. While it is a remote possibility, a summit eruption is not expected because the summit is deflating and not experiencing an unusual number of earthquakes.

It was reported that during 24-30 October fissure segment D from
Kilauea's 21 July fissure eruption continued to feed an advancing lava flow. Observations on 26 October confirmed that a tube-fed pahoehoe flow along the N margin of the main channel advanced 2.4 km from the channel end. A few small earthquakes were located beneath Halema'uma'u crater, and along the lower SW rift zone and S flank faults during the reporting period. [details] lundi, oct. 29, 2007
HVO reported that during 17-23 October fissure segment D from
Kilauea's 21 July fissure eruption continued to feed an advancing lava flow that frequently overflowed its channel edges. Activity was concentrated at the NE end of the channel where 200-500-m-long pahoehoe lobes built out in a fan shape to the NW, N, and SE. On 23 October, a lava flow traveled 1.5 km and entered the remains of a kipuka along the N margin of the flow field. A few small earthquakes were located beneath Halema'uma'u crater and the S flank during the reporting period. [details] jeudi, sept. 27, 2007
HVO reported that during 12-18 September fissure segment D from
Kilauea's 21 July fissure eruption continued to feed an advancing 'a'a lava flow that frequently overflowed its channel edges. Several of the lava flows that branched from the main channel continued to advance, widening the flow field. An 'a'a flow that developed within the previous two weeks crusted over and pahoehoe breakouts issued from near the flow front on 14 September. A few small earthquakes were located beneath Halema'uma'u crater, the S flank, and the lower SW rift zone during the reporting period. [details] |
