Tephra deposit names: Out with the old, in with the new

Sometimes you just have to sit down and do it. Everyone is faced with this challenge at one time or another and scientists are no exception. Our research into the explosive history of Kilauea Volcano came to just such a head earlier this year.

    Hawaii is not the only island in the United States with an ongoing eruption involving hot lava and cold water.

    Around Pahala are several ash layers composed of fine-grained volcanic deposits, generally called “soil.” The ashes are a mixture of altered glass, rare vitric (glassy) shards, Pele’s hair, pumice, and olivine crystals. They are derived from pristine ash-fall deposits, weathered and reworked ash, and sediments. Ancient soil horizons are present in some localities.

    Kilauea Volcano’s summit eruption in Halemaumau Crater began in March 2008. Since that time, countless changes have occurred. The crater enclosing the lava lake (called the Overlook crater) has enlarged through rockfalls, and explosions have thrown spatter around the crater and onto the rim of Halemaumau itself. The lava-lake level has fluctuated, leading to several overflows of lava onto the Halemaumau Crater floor.

    A fire hose of lava continues to pour into the sea at the Kamokuna ocean entry, the U.S. Geological Survey Hawaiian Volcano Observatory reports.

    Since its initiation on July 26, 2016, the Kamokuna ocean entry has drawn thousands of visitors eager to witness the creation of new land. The interaction of hot lava and cold seawater produces beautiful and powerful displays that can only be observed on Hawaii Island.

    HILO — National Park Service officials are again pleading with visitors to heed safety warnings.

    This is the story of how a new concept — slowly pulsing magma supply to Kilauea — emerged from observations of the Overlook lava lake in Halemaumau.

    If something is hot enough, it emits light in wavelengths that are visible to the human eye. This is called incandescence. If you’ve ever seen the red-, orange-, or yellow-ish glow from Kilauea Volcano’s lava lake or an active lava flow, then you have observed incandescence.

    Unknown to thousands of visitors in Hawaii Volcanoes National Park, a simulated Mars landing mission unfolded on Kilauea Volcano for two weeks in September.

    If you’re on Oahu and notice an unusual airplane landing and taking off from the Kaneohe Bay Marine Corps Base, you might be seeing NASA’s ER-2 aircraft.

    The “firehose” flow is no longer visible at the Kamokuna ocean entry, Hawaiian Volcano Observatory scientists reported Thursday.

    HILO — The seaside cliff near the Kamokuna lava ocean entry was preparing to split as a ground crack widened to more than 2 feet, geologists said Thursday.

    During Hawaii Island’s 8th annual Volcano Awareness Month (January 2017), we offered a series of Volcano Watch articles about four of the five U.S. Geological Survey (USGS) volcano observatories: Cascades (CVO), Alaska (AVO), California (CalVO), and Yellowstone (YVO). Today, we complete the series with a brief history of America’s first volcano observatory — the Hawaiian Volcano Observatory (HVO).

    Hawaii Island’s 2017 Volcano Awareness Month is almost over, and our Volcano Watch series about U.S. Geological Survey volcano observatories and their connections to Hawaii is also coming to an end. This week, we visit the observatory that monitors a volcano that produced some of the largest eruptions known on Earth — Yellowstone!

    This month, our Volcano Watch articles are exploring U.S. Geological Survey (USGS) volcano observatories and their connections to Hawaii. This week: California, here we come!
