A researcher at the University of Hawaiʻi at Hilo who specializes in economic geography has generated mapping data showing the possible effects if or when the current lava flow in lower Puna cuts off the highway and then reaches the shore.

Mark Kimura is an affiliate faculty member of the Department of Geography and Environmental Sciences, and when the Hawaiʻi County Civil Defense and Hawaiian Volcano Observatory started discussing worst case scenarios of the current lava flow, he saw a need for easily accessible information about demographics and businesses in Puna that would help the community make important decisions. He started posting his maps and analysis on a Facebook page called Lower Puna Infographics by Mark Kimura.

“The more I read comments (on my Facebook page), the more firmly I’m convinced that education is crucial across the island both geographically and demographically,” says Kimura. “I try my best to make my graphics both accurate and concise at the same time, but there are limits for that effort. The existence of UH Hilo is also crucial in a situation like this. I wouldn’t have been able to do this without my access to UH Hilo’s resources, mainly software licenses, and connections with other scientists and staff.”

For his analysis, Kimura is using geographic information systems or GIS, which are computer systems designed to capture and analyze spatial or geographical data. For many of the images, he is using a GIS tool called Esri Community Analyst, which he learned as a former postdoc and member of the UH Hilo Spatial Data Analysis and Visualization Lab. Esri is used by organizations and communities around the world that are using GIS to increase spatial literacy, protect the environment, assist with disaster response, and support humanitarian affairs. With this computerized tool, Kimura created the maps of Puna and pulled up the statistics.

Kimura says the making of the maps is helping him to grow as a scientist and as a person.

“To be honest, I’m a bit scared of possible impacts my (Facebook page) may have on people,” he says. “The responsibilities that come with the information I share feel too much at times. But my salary for the past three years has been paid by tax payers, so if I can help people using my skills and resources, I have to do this. After reading people’s comments by people who live in the affected area and those who have their loved ones living in lower Puna, I can’t stop.”

Kimura wishes to add this disclaimer: The information did not go through the peer review process, so he does not claim accuracy of the graphs. He notes that he does his best in the hopes that this will provide people in lower Puna and the rest of the world with some insights.

    Hey, great job Mark. I live in Leilani Estates, so it’s good to get this kind of detailed information. Thanks. Richard.

    Aloha Mark,

    I was recently made aware of this situation in a lecture in my Hawaiian studies/Botany class. In order to decrease the worry of many people on the island of Hawaii and throughout the world in general, is it possible to drill release holes off the coast of our islands? This would have the same concept as drilling for oil. Maybe this could offset the amount of lava that could hit and destroy residential areas, human life and agricultural upbringings, to say the least. I am aware of the concern for marine life but as late in the game as we are, this would seem to be a logical solution. Letting mother earth breathe and giving her an opportunity to release much built up pressure while at the same time easing the worry and fear of many individuals. This may even attract national attention and perhaps funding from major corporations and industries may be donated to fund a project such as this. This would also give scientist a unique chance for research and the education that could be passed along from this would be invaluable. Well, this was just a thought of mine. I think it makes complete logical sense, of course there are a lot of content that would need to be ironed out, sort of speak but definitely worth looking into if not already in process.

      Hi Lynn,

      I wish I could answer your question, but I don’t study the behavior of the lava itself. If you live in Big Island, there’s a lecture by Dr. Ken Hon tomorrow at UH Hilo campus UCB 100.

      Mark
