HAWAI`I ISLAND, Hawaii —January 2014 is “Volcano Awareness Month,” and Kilauea Volcano will be the focus of two talks presented at the University of Hawai‘i in the coming weeks.
Both presentations are free and begin at 7:00 p.m. in the University Classroom Building, Room 100, on the UH–Hilo main campus, 200 W. Kawili Street, in Hilo. A campus map is online.
According to Swanson, the footprints were left by people walking on muddy volcanic ash likely deposited within several hours of the 1790 eruption, which killed as many as several hundred people. “Probably some of the people who died during the eruption left the footprints we see today,” he said.
Fissure eruptions frequently occur on Hawaiian volcanoes and are the most common style of eruption on Earth. Yet, due to their complexity, they are not well understood. Carolyn Parcheta, in collaboration with HVO geologists, has taken on the challenge of figuring out how fissure eruptions work.
According to Parcheta, understanding what happens during a fissure eruption can help determine how magma behaves below ground seconds to minutes before it erupts, as well as how lava creates new surface features after it is erupted. “We are learning how magma and gas work together to form the lava fountains erupted from fissures, and how that lava then produces lava flows, spatter cones, and other features associated with fissure eruptions,” she said.
Parcheta will talk about her investigations of the 2011 Kamoamoa and 1969 Mauna Ulu fissure eruptions and what she has discovered from them in her Jan. 16 presentation.
These UH-Hilo presentations are two of many programs offered by HVO during Hawai‘i Island’s fifth annual Volcano Awareness Month. For more information about these and other Volcano Awareness Month talks, visit the HVO website, email askHVO@usgs.gov, or call (808) 967-8844.
