Photo and Video Chronology — December 30, 2024 — Kīlauea summit eruption continues
Maintenance of the Hawaiian Volcano Observatory's instrumental monitoring network is an ever-ongoing process, but it is especially important during eruptions. Here, two scientists perform repairs on a gas monitoring station located just west of Kaluapele—Kīlauea's summit caldera—on Saturday, December 28, 2024. An upward-looking spectrometer measures the amount of sulfur dioxide (SO2) passing over the station, and when combined with data from other similar instruments located downwind of the ongoing eruption within Halemaʻumaʻu crater, an approximate SO2 emission rate can be calculated.
