Kīlauea summit changes - Dec. 25 to 27, 2020

The KW webcam has captured the recent shift in vent activity in Halema‘uma‘u crater wall at Kīlauea's summit. The first image, taken on December 25, 2020, just after 6 p.m. HST shows the northern/eastern vent as more vigorous. HVO field crews observing the activity noted that at approximately 2:40 a.m. HST December 26, 2020, activity at west vent in the wall of Halema‘uma‘

Changes at Halema`uma`u Over Time

This is a comparison of photos taken from the same location in the Volcano House on May 19 and June 13, 2018. The focal length of the lens for each photo is almost the same. The photos show the enlargement of Halema‘uma‘u laterally and vertically. Note how much lower the rim is relative to the tree in the lower photo.

[HTcam] Halemaʻumaʻu Overlook Vent Thermal from Halemaʻumaʻu Overlook

This image is from a temporary thermal camera located on the south rim of Halemaʻumaʻu and looking steeply toward the north at the active Halemaʻumaʻu vent. The temperature scale is in degrees Celsius up to a maximum of 500 degrees (932 degrees Fahrenheit) for this camera model, and scales automatically based on the maximum and minimum temperatures within the frame.

An Endangered Honeycreeper, the `Akeke`e (Kauai Akepa), in Hawaii

Many species of Hawaiian honeycreepers have persisted into the 20th century because high elevation rain forests on the islands of Kaua’i, Maui, and Hawai’i are cool enough to limit transmission of introduced avian malaria (Plasmodium relictum). Malaria transmission is tied closely to the effects of temperature on development of malarial parasites within their

Lava flows can travel long distances if they develop insulating conduits for transporting fresh molten lava to the flowfront. These conduits are, of course, called lava tubes.

August 25, 1996

In a double handful of molten magma (weighing about a pound), there is less than a tenth of an ounce, by weight, of dissolved gas—roughly the same weight as a pinch of table salt. Yet this tiny amount of gas can drive spectacular lava fountains hundreds of feet into the air.

Floating hydrophones and sonobuoys recorded the crackling and grinding noises that are often indicative of an ongoing submarine eruption, but the University of Hawaii Pisces V dive team and their USGS, Bishop Museum, and University of Washington collaborators found no red lava or active eruptive vents as they explored the underwater world of Lo`ihi volcano last week.

In response to the intense off-shore earthquake swarm that began on July 16, scientists at the University of Hawaii (UH) received funding for a research cruise to investigate possible changes at Lo`ihi.

It was only 42 years ago that Lo`ihi and four other seamounts were discovered during a bathymetric survey of the area south and southeast of the Big Island by the U.S.S. Patapsco.

The ground's surface around the active Hawaiian volcanoes Kīlauea and Mauna Loa is constantly changing. Lava flows laminate their sides during active eruptions.

On Wednesday, July 17, a 10-year-old boy slipped into a large crack in the Sulphur Banks - Steaming Flats area of Hawaii Volcanoes National Park. Unfortunately, the crack was also a vent for steam, which scalded the young visitor and caused second-degree burns.

July 12, 1996

The 13-year-old eruption along Kīlauea's East Rift Zone has continued unabated since the pause from May 30 to June 4. Over a period of 18 hours on May 29-30, lava gradually stopped issuing into the tube system from the vent on the flank of the Pu`u `O`o cone.

The long-standing eruption of Kīlauea Volcano continues unabated this week as lava tubes spill 14 million cubic feet of lava per day into the ocean at Kamoamoa on Hawaii's southeast coastline. Flows have inundated the area almost continuously since 1992.

Each year, the Hawaiian Volcano Observatory records thousands of earthquakes with its island-wide network of seismographs. Often, many of these earthquakes are directly related to volcanic activity and indicate movement of magma beneath the summits or rift zones of the volcanoes.

The eruption along Kīlauea's East Rift Zone continues after a pause from May 30 to June 4. Over a period of 18 hours on May 29-30, lava gradually stopped issuing into the tube system from the vent on the flank of the Pu`u `O`o cone.

When Polynesian voyagers reached Hawaii, they found volcanic islands much like their homeland in the South Pacific. Geologically speaking, the Marquesas, Tuamotus, Society Islands, Cook Islands, and Austral Islands are about the same age and made of the same kind of volcanic rocks as are the Hawaiian islands.
