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.

    Ten years ago, shortly after 7 a.m., on Sunday, Oct. 15, 2006, two damaging earthquakes struck off the northwest coast of the Big Island — a magnitude-6.7 earthquake beneath Kiholo Bay and a magnitude-6.0 earthquake offshore of Mahukona.

    Kilauea Volcano’s summit lava lake rose to within 54 feet of the crater rim Tuesday under the watchful eyes of the USGS Hawaiian Volcano Observatory.

    Characterizing earthquakes is one of the most important activities we do at the U.S. Geological Survey Hawaiian Volcano Observatory. Seismicity helps us monitor the “pulse” of volcanoes and can be a first indication of an impending eruption.

    KAILUA-KONA — Kilauea Volcano continues to erupt at its summit and at the Puu Oo vent on its East Rift Zone, U.S. Geological Survey Hawaiian Volcano Observatory scientists reported Thursday.

    Recent visitors to the Kamokuna ocean entry have been greeted with the spectacular sight of Kilauea’s lava pouring into the sea to form some of the newest land on Earth. The vigorous interaction between molten lava (2,000 degrees Fahrenheit) and relatively cool seawater (around 80 degrees Fahrenheit) seldom fails to capture the imagination and engage the two particular senses of hearing and sight.

    In 1870, while exploring the American West, Nathaniel P. Langford encountered an “immense volume of clear, sparkling water projected into the air to a height of one hundred and twenty-five feet.” He named this volcanic feature “Old Faithful.” This magnificent geyser became the signature attraction of Yellowstone National Park and remains a popular visitor stop today.

    HILO — Kilauea’s summit was rocked by earthquakes Wednesday afternoon as its churning lava lake put on a show for visitors in Hawaii Volcanoes National Park.

    HAWAII VOLCANOES NATIONAL PARK — The journey starts deep within the Earth and ends in one spectacular collision.

    HAWAII VOLCANOES NATIONAL PARK — The Kalapana lava flow has drawn thousands of people, some of whom risk life and limb by playing with the molten heart of the Earth.

    At 10:02 p.m., Saturday, Aug. 6, a section of altered, thermally-stressed rock enclosing the Halemaumau Crater lava lake detached from the vent wall and plummeted into the molten lava. Tons of rocky debris impacting the lake surface triggered a violent explosion of volcanic gas, incandescent spatter (blobs of molten lava), and pieces of solid rock that sent a jet of glowing debris skyward.

    In 1902, visionary geologist Thomas Jaggar — founder of the Hawaiian Volcano Observatory — traveled to the Caribbean Island of Martinique, where he witnessed first-hand the aftermath of the deadly Mount Pelee eruption. More than 30,000 people had been killed by the eruption, and the devastation he observed contributed to Jaggar’s lifelong work to “protect life and property on the basis of sound scientific achievement.”

    KALAPANA — “How far is it?”

    The lava flow from Kilauea’s Puu Oo vent makes its way to the ocean after crossing the emergency access road. The lava flow, known as 61G, reached the ocean early Tuesday.

    HILO — Lava began spilling into the ocean early Tuesday morning, sending a plume of volcanic gas skyward while adding new land to Hawaii Island’s southeast coast as waves crashed into 2,000-degree molten rock.
