Water, ash, and the great unknown of explosive volcanic eruptions

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.

HVO’s geological sample collections are an important resource

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.

Report finds failures in county’s lava response

Hawaii County has released a report largely critical of its own response to the monthslong eruption of Kilauea volcano in 2018 — in which Halema‘uma‘u 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.

Hula about more than dance movements

For Kumu Hula Lona Warner, who started Halau Makanani in her Kailua-Kona carport at age 63, hula is about more than dance movements. It’s about life and mana.

Who and what is the scientist-in-charge?

Today’s article, written by HVO Scientist-in-Charge Christina (Tina) Neal, is the second in a series of articles about HVO people and jobs during Volcano Awareness Month 2020. Next week, another HVO team will write about its work.

HVO scientists mentor STEM students at national conference

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.
