Mike Zoeller and Adam Mosbrucker play key roles within the United States Geological Survey (USGS) Volcano Hazards Program. Both Mike and Adam rely heavily on the use of lidar and its derivative products to support applied science projects related to the specific volcanology of their respective regions, the Hawaiian Volcano Observatory (HVO) and the Cascades Volcano Observatory (CVO), respectively. In this episode, we chat about some of the exciting and novel applications of lidar within their work such as locating landing zones for helicopters and finding ideal placement locations for telemetry and solar power systems for GNSS instrumentation. We also discuss how lidar is utilized to constrain lava flow, develop geophysical models of underlying volcanic mechanics and get a handle on long-term sediment storage and basin yields.
