In the video above dated Sept. 29, 2012, Ken Hon, professor of geology and volcanology, and colleague Peter Mills, professor of anthropology, teach students  in a UH Hilo volcanology class, along with visiting students from Stanford University, how to collect data in the field with a thermocouple and radiometer. This is a Kilauea lava flow on the Big Island of Hawai‘i, high up on the pali (cliffs). Note: there is no narrative in this video.

Kenneth Hon, professor of geology and volcanology at the University of Hawai‘i at Hilo, specializes in volcanology, petrology and mineralogy. Hon has studied volcanoes in Hawai‘i, the continental United States, and Russia. His research interests concentrate on basaltic volcanoes in Hawai‘i and large ash-flow caldera eruptions. He also teaches courses in physical geology, geology of the Hawaiian islands, mineralogy, and petrology.

“I’m probably best known for my work on the mechanics of pahoehoe lava emplacement, but all lava flows have a special place in my heart,” he says. “I love trying to gently coax a volcano’s story out of the rocks and minerals. But if that doesn’t work, grinding them to bits and torturing them in hot furnaces and under electron beams is kind of fun, too. One way or the other, they eventually talk and say some pretty interesting things.”

Hon also makes educational films about volcanic eruptions on the Big Island. He’s part of a team of filmmakers at Volcano Video Productions, where he narrates, shoots, edits, and writes scripts for videos. The films are shown in the theater at Hawai‘i Volcanoes National Park. A lot of the footage is used in many different TV programs on the major networks, Discovery Channel, Learning Channel, and others, as well as at a number of museums including the American Museum of Natural History.

Hon also conducts geoarchaeology research. In 2003, he teamed up with UH Hilo anthropology professor Peter Mills as investigators on a Major Research Instrumentation Grant from the National Science Foundation. That initial grant was used to found the UH Hilo Geoarchaeology Laboratory to specialize in non-destructive analyses of basalt and volcanic glass artifacts from the Pacific using an Energy Dispersive X-Ray Fluorescence spectrometer that allows rapid study of the material without any damage to the artifacts. The EDXRF is used to detect and record the geochemical “fingerprints” of the stone tools that prehistoric Hawaiians quarried from various sites, and tracks the extent to which that material was traded throughout the islands.

Hon also runs the UH Hilo Electron Microprobe Lab. The electron microprobe, called an Applied Research Laboratories Scanning Electron Microprobe Quantometer or ARL SEMQ, has been completely renovated with a grant from the National Science Foundation with assistance from the USGS Hawaiian Volcano Observatory. UH Hilo works cooperatively with HVO in analyzing lava samples to determine their thermal and chemical history.

The ARL SEMQ is running the most recent version of Probe for Windows analytical software, which is fully integrated with image analysis software and hardware from SIS. It is capable of quantitatively analyzing spots of 1-2 microns and can also produce backscatter electron and x-ray element maps.

The microprobe is housed in the UH Hilo Geoarchaeology Laboratory along with the EDXRF, which is capable of analyzing whole rocks. Both instruments are wired to the adjacent teaching laboratory and can be used by students as part of geology and archaeology courses.

“We are the only undergraduate liberal arts college in the U.S. with our own microprobe,” says Hon.

Prior to coming to UH Hilo, Hon worked for 15 years at the U.S. Geological Survey in the Volcano Hazards Program, including three years at the Hawaiian Volcano Observatory.

“During my tenure at HVO, the town of Kalapana was overrun by lava and I was intimately involved with monitoring the progress of lava flows and evacuating residents,” he says. “This experience had a profound effect on me and made me much more interested in making science more applicable to people.”
