Lidar, which stands for Light Detection and Ranging, uses laser pulses to create precise, 3D maps of the earth’s surface. For HVO, this new tool will be invaluable in tracking ground deformation, measuring lava flow thickness, and mapping craters and other geological features. The system’s ability to measure subtle changes in topography is crucial for early detection of volcanic hazards, offering scientists a clearer picture of how Hawaii’s active volcanoes evolve over time.
The system’s first successful flight is a milestone for HVO’s efforts to improve the accuracy and frequency of their topographic monitoring. The airborne lidar unit is mounted on a helicopter and can scan large areas quickly, capturing data that would be difficult, if not impossible, to obtain through ground-based surveys alone. This will enhance HVO’s ability to respond rapidly to eruptive events, minimizing risks to communities and infrastructure.
This upgrade marks a significant leap in HVO’s capabilities, and it comes at a time when precision and speed in data collection are more critical than ever. By adopting airborne lidar, HVO is positioning itself at the forefront of volcano monitoring technology, offering a better understanding of Hawaii’s shifting landscape and improving public safety through enhanced volcanic hazard assessment.
