| | Jul 14 2017 - 9:26am | Comments

The new “Geologic map of the northeast flank of Mauna Loa volcano, Island of Hawaii,” the culmination of many years of work by Hawaiian Volcano Observatory geologists, was recently published by the U.S. Geological Survey. The work was spearheaded by John P. Lockwood (affectionately known as “Mr. Mauna Loa”), who is now retired from USGS and HVO, and Frank Trusdell, HVO’s current Mauna Loa Project geologist.

    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.

    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).

    HILO — A new viewing area for the Kamokuna lava ocean entry opened Tuesday after two days of closure due to a New Year’s Eve lava delta collapse.

    A large section of the 26-acre lava delta formed by the 61g lava flow collapsed into the ocean around 2:45 p.m. on New Year’s Eve, launching showers of volcanic rock into the air, and creating a flurry of large waves that eroded away a portion of the older sea cliff and viewing area.
