Hawaiian Volcano Observatory (HVO)

The Hawaiian Volcano Observatory (HVO) is a scientific institution that monitors and studies volcanoes, primarily on Hawaii’s Big Island. Operated by the U.S. Geological Survey, it uses specialized equipment to track volcanic activity, seismic signals, gas emissions, and ground deformation. This information helps scientists understand volcano behavior, predict eruptions, and provide warnings to protect communities and visitors. HVO's work is crucial for public safety and advancing geothermal and volcanic research, making it a key resource for both local authorities and the global scientific community.
