The Story of the HVO: 100 Years of Tracking Eruptions and Earthquakes

Detailed Description

Thomas A. Jaggar founded the Hawaiian Volcano Observatory in 1912 and served as its Director until 1940. Shown here in 1925, Jaggar is at work in HVO's first building, which, at the time, was located on the northeast rim of Kīlauea Volcano's summit caldera, near the present-day Volcano House hotel. Today's HVO Scientist-in-Charge presents the story of America's first volcano observatory in a talk at the Kīlauea Visitor Center at 7 p.m. on Jan. 17. Photo credit: USGS photo.
