Kilauea volcano (Hawaii), news: new gas vent in Halemau'uma'u crater

mardi mars 18, 2008 00:47 |

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.

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]
