Magma: What’s hot and what’s not

| | Nov 9 2017 - 3:40pm | Comments

Scientists at the U.S. Geological Survey’s Hawaiian Volcano Observatory routinely collect lava samples from Kilauea and use the chemistry of these samples to infer the temperature of magma (molten rock below Earth’s surface).

    The New Year is just around the corner, so it’s time to remind everyone that January is Volcano Awareness Month on the Island of Hawaii.

    There are more than 1,500 active volcanoes on Earth. With many millions of people living and working in their shadows, developing ways to co-exist safely with potential volcanic threat is essential. To do so, those at risk need to know the type and severity of hazards they may face.

    As winter approaches, many Hawaii Island residents eagerly await the appearance of sub-tropical snow atop Mauna Kea and Mauna Loa. Another common occurrence on Hawaii Island during winter months is the frequent interruption of the steady northeasterly trade winds. These winds, or the lack of them, play a leading role in determining where volcanic air pollution from Kilauea, known as vog, is distributed across the island, and sometimes the state.

    Ask almost any volcanologist and field technician what they consider to be the most important and yet potentially dangerous aspect of their work on active volcanoes and they will probably say, “flying in a helicopter to remote areas to make observations or install and maintain monitoring instruments and radio systems.”

    Using the Global Positioning System (GPS) in your cellphone or car has become an everyday occurrence that many of us take for granted and now consider indispensable. GPS-enabled gadgets are, in fact, everywhere; watches, cameras, luggage and dog tags can all tell us exactly where on the planet they are.

    The lava lake within Halemaumau Crater at the summit of Kilauea Volcano is creating a scene remindful of a messy barbershop floor, except that it’s acres and acres wide rather than a few square feet. The ground downwind of the crater is strewn with Pele’s hair, and it is almost impossible to avoid stepping on it.

    The Kilauea volcano lava lake has burped fresh lava onto the floor of the Halemaumau crater for the first time since spring, 2015.

    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.
