HVO Releases New Photo of Halemaumau Crater

One month ago the summit lava lake was at the rim of the Overlook crater (the small crater in the center of the photo), spilling lava onto the floor of Halemaʻumaʻu Crater (the larger crater that fills much of the photo), creating the dark flows surrounding the Overlook crater.

Since that time the lava lake has dropped, associated with summit deflation, and today the lake level was about 60 meters (200 feet) below the Overlook crater rim. The stack of recent overflows is visible on the wall of the Overlook crater as the layer of dark lava atop the older, light colored lava forming the majority of the Overlook crater wall.

The photo is taken from the southeast rim of Halemaʻumaʻu Crater. The closed Halemaʻumaʻu overlook is in the upper left corner of the photo. Jaggar Museum and HVO can be seen as a small bump on the horizon in the upper right portion of the photograph.

Lava Lake at Halemaumau Crater Continues to Drop

Kīlauea Volcano’s summit lava lake continued to drop today (May 15, 2015).

Measurements of the lake surface late this afternoon showed that it was 62 m (203 ft) below the top of the newly-created vent rim, a ridge (or levee) of solidified lava about 8 m (26 ft) thick that accumulated on top of the Halemaʻumaʻu Crater floor from multiple overflows of the vent during the past two weeks.

Webcam Captures “Bathtub Ring” Falling Into Lava Lake

This sequence of HVO webcam images of Kīlauea Volcano’s summit vent, recorded between 1:28 and 1:32 p.m., HST, on May 12, 2015, captures the moment a section of the dark-colored “bathtub ring” (a veneer of fresh lava that coats the vent wall as the lava lake level drops) fell into the lava lake (center).

The lava veneer collapse, which produced a visible cloud of rock and lava fragments, agitated the lava lake surface and exposed lighter-colored layers of older rock in the vent wall (right).

VIDEO – Lava Lake Remains High

The lava lake in the Overlook crater, within Halemaʻumaʻu Crater at Kīlauea’s summit, remains at a high level and close to the Overlook crater rim. Overflows onto the Halemaʻumaʻu Crater floor have built up the rim of the Overlook crater several meters, and recent overflows are visible in the right side of the photograph.

Spattering was vigorous today in the southern portion of the lake. From this view, the spattering was hidden behind a portion of the Halemaʻumaʻu Crater wall, but airborne spatter can be seen in the bottom left portion of the photo.

Over the past week, the summit lava lake in the Overlook crater rose and spilled out onto the floor of Halemaʻumaʻu Crater, creating the dark flows in the south part of Halemaʻumaʻu (left side of crater from this direction). The extent of the lake itself, set within the Overlook crater, is slightly difficult to distinguish from this view but the spattering at the lake margin is visible. The overflows onto the Halemaʻumaʻu Crater floor, not counting the area of the lake itself, total about 11 hectares (28 acres).

Lava Lake Overflows Vent Rim

Kīlauea Volcano’s summit lava lake, which was about 12 m (40 ft) below the vent rim on April 25 (left), overflowed the vent rim for the first time at about 9:40 p.m., HST, on April 28. As of noon on April 29 (right), the lava lake had overflowed the vent rim several more times. These Webcam images capture the summit vent before and after the overflows. (Click to enlarge)

Rise in Lava Lake Creates Surge in Visitation at Volcanoes National Park

Thousands of additional visitors are flocking to Hawai‘i Volcanoes National Park to witness the large lava lake steadily rise at the summit of Kīlauea volcano. lava Lake 427

Over the last several days, visitors waited up to 30 minutes or longer to park. To ease traffic once the Jaggar Museum and Kīlauea Overlook parking lots fill up, rangers are currently redirecting vehicles during peak visitation hours to park at the Kīlauea Military Camp ball field. From there, visitors can hike one mile to the Jaggar Museum observation deck, the closest and best vantage point to view the spectacular lava lake.

“Visitors should come prepared to ensure a safe and enjoyable park experience,” said Superintendent Cindy Orlando. “We encourage people to avoid peak hours, and arrive after 10 p.m. and before 4 a.m. if possible, or they will likely wait in line for parking. The park remains open 24 hours a day,” she said.

Tips for an optimal viewing experience:

  • Be prepared to hike one mile each way between Kīlauea Military Camp ball field and the Jaggar Museum observation deck on Crater Rim Trail. Wear sturdy closed-toe shoes, bring rain gear, water, binoculars, a flashlight, and extra batteries.  ​
  • Carpool if possible to reduce the number of vehicles in the parking areas.
  • As a courtesy to other visitors, no “tailgating” in the Jaggar Museum or Kīlauea Overlook parking lots. Choose another picnic location so others have a chance to view the eruption.
  • To observe viewing and weather conditions, monitor the USGS Hawaiian Volcano Observatory webcams. The KI camera provides a panoramic view of Halema‘uma‘u Crater from HVO.
  • High levels of dangerous sulfur dioxide (SO2) gas and volcanic ash can be blown over Jaggar Museum by southerly winds. These gases are a danger to everyone, particularly to people with heart or respiratory problems, young children and pregnant women. Kīlauea Visitor Center offers updates on air quality 24 hours a day, and visitors can monitor the Hawaii SO2 network website.

In addition, the public is reminded that park entrance fees apply and that the use of unmanned aircraft (drones) is prohibited in all national parks.

The flow surface consists of numerous scattered pāhoehoe lobes, and the advancement of the flow as a whole results from the combined, incremental movement of these individual lobes.

Lava Lake Continues Tantalizing Trend – Cool Youtube Clip of Lava Reaching the Ocean

The lava lake within Halema‘uma‘u Crater at Kīlauea is tantalizing visitors and park staff as it continues its current trend of repetitive rising and falling, attracting many to the best vantage point: the overlook at Jaggar Museum.

Photo taken Friday, October 19 courtesy of the U.S. Geological Survey Hawaiian Volcano Observatory

Scientists at the U.S. Geological Survey’s Hawaiian Volcano Observatory report that the lava lake rose to levels approximately 125 feet or less beneath the crater floor this morning, and HVO webcams today suggest the lake rose even higher, before sinking again this afternoon.

Dr. Jim Kauahikaua, HVO’s Scientist-in-Charge, says the lava lake will be visible from the overlook at Jaggar Museum if it comes within about 65 feet of the crater floor. The lava lake reached its highest level today since forming after an explosive eruption on March 19, 2008.

Meanwhile, rangers urge park visitors to obey traffic signs and to be safe. Visitors are gathering at park overlooks after dark to view the dramatic glow that lava beneath the surface casts upon clouds and the plume of volcanic gas, hoping molten lava will rise high enough to be seen. The parking lot at Jaggar Museum is busy with hopeful observers, who are reminded to park only in marked stalls and heed all signs.

All visitors who plan to come after dark are urged to bring flashlights, especially those who park at Kīlauea Overlook, which affords panoramic views of the crater and Kīlauea caldera. Earth cracks, rocks, and other hazards are not easily seen in the dark.

In addition, several pairs of nēnē, the federally endangered Hawaiian goose, are beginning to nest near the Jaggar Museum parking lot, and are sometimes spotted along roadsides and trails. Cars are the leading cause of nēnē fatalities, and drivers are cautioned to be alert, and to drive the speed limit.

“Safety is our number one priority,” said Park Superintendent Cindy Orlando. “We encourage everyone to visit during this fascinating episode, but to exercise caution. Staff will be assisting visitors with parking and interpretation of the current activities. If people come prepared and proceed as directed, they should have an unforgettable experience,” she said.

Hawai‘i Volcanoes National Park is open 24 hours a day.
