The presence of water in Halema’uma’u has sparked an important discussion about what the pond means for future eruptions at Kilauea Volcano. There are no written records of water at the summit, so to guide the discussion we need information about magma-water interaction from deposits of the past.
In the past, HVO would occasionally post images of people collecting lava samples on our website. These photos usually featured a person (with little-exposed skin) holding a rock hammer, with a metal bucket nearby. The bucket contained water to quench the sample, solidifying the hot lava into a cold glass. Natural-fiber or heat-resistant gloves, and sometimes a face mask, protected the sample collector from heat radiating off the 2,100-degree lava. The hammer was used to scoop some of the molten material into the bucket, which would hiss and steam in reaction; more water would be added to cool down the sample so it could be placed in a cloth bag.
Last weeks Volcano Watch provided details of events leading up to the dropping of bombs on a Mauna Loa lava flow on Dec. 27, 1935. Heres the rest of the story.
In late February, Hawaii media reported on the recent discovery of two bombs on the north flank of Mauna Loa, but details were lacking. Today, we offer more info.
Hawaii County has released a report largely critical of its own response to the monthslong eruption of Kilauea volcano in 2018 in which Halemaumau crater threw ash 30,000 feet into the air, lava destroyed a 716 homes and structures in lower Puna, and hundreds of residents were displaced.
The origin(s) of volcanic ash deposits on the Hawaii Island have been an enigma, especially those found on and between Kilauea and Mauna Loa. We know that ash is from explosive eruptions, but the question has been from which volcano?
Portulaca sclerocarpa (also known as Ihi makole) is a critically endangered small succulent plant in the purslane family (Portulacaceae). It only occurs on Hawaii Island and on a small islet off the coast of Lanai. It can be found in various sites in Hawaii Volcanoes National Park, including the Puhimau thermal area.
The U.S. Geological Surveys Hawaiian Volcano Observatory recorded a magnitude-4.2 earthquake beneath Kilauea Volcanos south flank on Sunday evening.
When I was 7 years old, I won my countys earthquake safety poster contest. I remember going to a special award luncheon with the mayor, who complimented my work and gave me an Earthquake in a Can toy. Little did I know how much that event would influence my life.
The long-closed Thurston Lava Tube in Hawaii Volcanoes National Park could reopen within a month if a final repair project goes smoothly.
As many residents of the island of Hawaii can attest, volcanic gases can stinkliterally. But for those of us at the USGS Hawaiian Volcano Observatory (HVO) who are lucky enough to study those gases, our jobs are actually pretty amazing.
HILO On March 30, 2018, a change occurred within the ranks of the USGS Hawaiian Volcano Observatorys staff when geophysicist Asta Miklius retired.
About a month ago, I attended the 2019 National Diversity in STEM Conference, an annual meeting organized by the Society for Advancement of Chicanos/Hispanics and Native Americans in Science (SACNAS) and held in Honolulu this year.
HILO Over the last two centuries, six lava flows erupted from Mauna Loas Northeast Rift Zone and advanced toward Hilo.
