Automated tracking of lava lake level using thermal images at Kīlauea Volcano, Hawai'i
Journal of Applied Volcanology
Tracking the level of the lava lake in Halema'uma'u Crater, at the summit of Kīlauea Volcano, Hawai'i, is an essential part of monitoring the ongoing eruption and forecasting potentially hazardous changes in activity. We describe a simple automated image processing routine that analyzes continuously-acquired thermal images of the lava lake and measures lava level. The method uses three image segmentation approaches, based on edge detection, short-term change analysis, and composite temperaturedoi:10.1186/s13617-016-0047-0 fatcat:7pgw6tjga5crrb3yewt5jm6v3a
