Halemaʻumaʻu Crater is a pit
crater located close to caldera of Kīlauea in Hawaii Volcanoes National Park.
The approximately circular crater floor is 770 meters x 900 m and is 83 m below
the floor of Kīlauea caldera. Halemaʻumaʻu means "house of the `ama`u
fern" is home to Pele, goddess of fire and volcanoes, according to the
traditions of Hawaiian mythology. This place is burned like another planet with
constantly changing scenery especially the view of Halemaumau crater at night
is stunning. Pictures can't begin to capture how magnificent it is. The crater
is presently active, encompassing a lava lake. The current vent inside Halemaʻumaʻu
crater first erupted explosion on the night of April 9, 2008 that widened the
hole by an additional 15 to 30 feet, ejected debris over some 200 ft and
further damaged the overlook as well as scientific monitoring instruments.
The present lava inside the vent is
changing from 20 to 150 meters below the crater floor. The molten lava in the
vent, known as the Overlook Crater, became directly visible for the first time
from the Jaggar Museum overlook at the Hawaiian Volcano Observatory; the lava started
spilling over the rim of the Overlook Crater and onto the floor of Halemaʻumaʻu
Crater, ultimately adding approximately 30 feet of fresh lava to the crater
floor. The walls of the crater become destabilized by heating, weathering,
earthquakes and loss of support. They fall into the lava causing degassing of
the lava, the exsolution of gases happens rapidly, leading to the explosion.
Usually, the lava within the lake is 100 feet to 200 feet below the rim, but
recently the magma chamber that flows into the lava lake has shown increased
inflation, suggesting that lava is being driven into the lake from an
underground chamber below.
The lake level has since remained
close to the rim, with an additional minor overflow event in October 2016. Therefore,
early eruptions were recorded by oral history. One large eruption in 1790 killed
several people, and left footprints in hardened ash of some Hawaiians killed by
pyroclastic flows. However, the crater bottom was covered with lava, and the
south-west and northern parts of it were one vast flood of burning matter, in a
state of enormous ebullition, rolling to and fro its "fiery surge"
and flaming billows.
The Crater Rim is not paved, so
wear close-toed shoes with solid grip. Once you reach the overlook, you’ll be
peering into the volcano goddess Pele's sanctuary. Though her flows are
plunging into the ocean somewhere else, her home is in Halema'uma'u. Moreover,
cultural ceremonies are held and offerings are sometimes left for her on the
crater rim. It was like gazing at the
sun at noon-day, except that the glare was not quite so white. At uneven
distances all around the shores of the lake were closely white-hot chimneys or
hollow drums of lava, four or five feet high, and up through them were bursting
stunning sprays of lava-gouts and gem spangles, some white, some red and some
golden--a ceaseless bombardment, and one that fascinated the eye with its
unapproachable splendor. The meager distant jets, sparkling up through an
intervening gossamer veil of vapor, seemed miles away; and the further the
curving ranks of fiery fountains receded, the more fairy-like and beautiful
they appeared.
