Kilauea Volcano, Hawaii
The original Hawaii Volcano Observatory building, was used from 1912-1940's, when the Observatory was able to occupy a new building 200 m back from the caldera rim. In 1948 Hawaii Volcano Observatory moved to a building at the top of Uwekahuna Bluff on the northwest rim of Kilauea caldera; a new and larger building was completed in 1986.
