Update to Crater Rim Drive Lane Closure

The westbound lane fronting Steam Vents will be closed for up to 10 weeks, Monday through Thursday, while crews replace a deteriorated water main.

Weekly work will be completed during four 10-hour days, instead of five eight-hour days. There will be no construction work or lane closure in the area on Fridays.

Traffic controllers will alternate traffic flow through the single open lane, 7 a.m. to 5:30 p.m., Monday through Thursday. Wait times to pass the construction area should not exceed 15 minutes.

Both lanes will be open to traffic when there is no active construction.

The project will replace approximately 3,000 feet of failing pipe that supplies water to Jaggar Museum and the USGS Hawaiian Volcano Observatory.

 

Hawaii Volcano Observatory Update – Thermal Image Sequence of Lava Lake in Halemaʻumaʻu Crater

This thermal image sequence shows the typical motion of the lava lake in Halemaʻumaʻu Crater.

Thermal image sequence of summit lava lake motion... Click Picture to view the sequence.

Thermal image sequence of summit lava lake motion… Click Picture to view the sequence.

For scale, the lake is about 160 meters (520 feet) wide in this view. The clip spans about 12 minutes, and is shown at 30x speed. The lava upwells along the north margin of the lava lake (in this view, near the top of the image). The crust slowly migrates towards the south, where it sinks back into the magmatic system along the south and southeast margins of the lake (bottom of image). The surface moves at roughly 0.5 meters per second, or about 1 mile per hour. The lake surface consists of numerous thin plates of crust, separated by hot cracks. As the lake surface migrates, these plates split, merge and change shape.

Halema‘uma‘u Eruption Reaches Five-Year Anniversary

Kīlauea Volcano’s summit eruption within Halema‘uma‘u Crater marks its fifth year of continuous activity on Tues., Mar. 19.

To commemorate this anniversary, rangers at Hawai‘i Volcanoes National Park will offer additional “Life on the Edge” talks at the Jaggar Museum observation deck, which overlooks the fuming, enlarging summit vent. The 20-minute talks, offered on Mar. 19 at 10 a.m., 11 a.m., noon, 2 p.m., 3:30 p.m. and 5 p.m., encompass the dramatic geological and mythological history of Halema‘uma‘u Crater.

Kīlauea’s summit vent opened at 2:58 a.m., HST, on Mar. 19, 2008, when an explosive eruption created a gaping hole about 115 feet wide on the south wall of Halema‘uma‘u Crater.  Nighttime glow from this hole suggested the presence of molten lava, but it wasn’t until six months later that a lake of roiling lava deep within the vent was definitively observed by U.S. Geological Survey Hawaiian Volcano Observatory (HVO) scientists.

With the opening of the Halema‘uma‘u vent, already-high summit sulfur dioxide (SO2) gas emission rates increased even more, resulting in increased vog (volcanic air pollution) downwind.  Although the summit SO2 emissions have declined since 2008, they are still averaging 800-1200 tonnes/day, creating hazardous conditions along closed sections of the park’s Crater Rim Drive and poor air quality farther downwind of the vent.

Since 2008, rock collapses within the vent have enlarged its opening on the floor of Halema‘uma‘u Crater.  The vent is now about 520 feet by 700 feet (the area of about 21 Olympic-sized pools), and, according to HVO Scientist-in-Charge Jim Kauahikaua, is likely to continue growing through further collapses of overhung sections of the vent rim.

Halemaumau then and now1

Kīlauea Volcano’s summit vent  “then and now.”  In April 2008, a month after it opened, the vent within Halema‘uma‘u Crater was about 115 feet in diameter.  As of March 2013, it is more than 500 feet across. USGS photos.

Halemaumau then and now2

Kauahikaua describes the lava within the vent as a continuously circulating gas-rich “foam” that rises and falls depending on changes in Kīlauea’s subsurface magma pressure.  The lava lake reached its highest level to date on Oct. 26, 2012, when the lava surface rose to within 72 feet of the vent rim.

While the actual lava lake is not visible from safe viewing areas, its glow—the diffusion of incandescent lava light within the gas plume rising from the vent—is spectacular and easily observed from Hawai‘i Volcanoes National Park overlooks on clear nights.  When the lava lake level is especially high, park visitors can sometimes hear sharp sounds as rocks in the vent wall expand and crack due to the increased heat.

“The amazing beauty of this eruption, and the ease of viewing opportunities within Hawai‘i Volcanoes National Park, provides both visitors and residents with unforgettable experiences,” said Park Superintendent Cindy Orlando. “Where else in the world can you park your car, and walk just a few feet to behold the spectacle of one of the world’s most active volcanoes?”

Jaggar Museum and the overlook are wheelchair- and stroller-accessible. Other vantage points for viewing Halema‘uma‘u within the park include Kīlauea Overlook, Kīlauea Iki Overlook, and Keanakako‘i Overlook.

The summit eruption, Kīlauea’s second longest since the early 1900s, can also be experienced through photos, videos, and webcam images posted on HVO’s website (http://hvo.wr.usgs.gov).  A USGS Fact Sheet about this ongoing eruption is currently in press, and will be available online in the coming months.
