USGS Geophysicist J. Chang On The 2018 Kīlauea Eruption & Citizen Science

9:11 PM · Nov 16, 2020

Full presentation on the impacts of citizen science during the 2018 eruption of Kīlauea, given by Jefferson Chang, Geophysicist at USGS. Chang worked with students from University of Hawaiʻi at Hilo to deploy sulfur dioxide (SO2) in Pāhoa and broadcasted the data collected in real-time. The equipment used by USGS during the eruption provided key monitoring of activity between the Kīlauea Summit, Puʻu ʻŌʻō, and the site of the eruption in the Lower East Rift Zone. Jefferson Chang finishes up by detailing a crowd-sourced, affordable seismic monitoring station that the community can buy to help USGS bolster its monitoring. Details from USGS: " Emerging tech as STEM platforms in problem-based learning (Kīlauea)" "Detailed Description USGS–Hawaiian Volcano Observatory Geophysicist Jefferson Chang talks about technologies that track activity at Hawaiian volcanoes and how crowdsourcing and citizen science can contribute to a greater understanding of hazards, in this presentation to the 2020 SACNAS Advancing Hispanics/Chicanos & Native Americans in Science virtual conference held October 19-24, 2020 ( During Kīlauea’s 2018 eruption, Jefferson met with a group of students from the Teaching Through Technology (T3) Alliance, a University of Hawaiʻi at Hilo Upward Bound program. The students created sulfur dioxide sensors and placed them in communal areas in Pāhoa to measure the particulate and sulfur concentrations in the air. The students broadcast data to the internet so people could monitor local changes in real-time. These air quality sensors were very helpful during the eruption, and can be used in many other communities to measure air quality changes brought on, for example, forest fires. Jefferson also talks about HVO’s monitoring of Hawaiian volcanoes, and how the community can set up a small, personal seismometer called Raspberry Shake, that will contribute data to a globally crowd-sourced earthquake monitoring network.
