Monitoring
Thomas A. Jaggar, the observatory's founder, attempted a summit expedition to Mauna Loa to observe its 1914 eruption, but was rebuffed by the arduous trek required (see Ascents). After soliciting help from Lorrin A. Thurston, in 1915 he was able to persuade the US Army to construct a "simple route to the summit" for public and scientific use, a project completed in December of that year; the Observatory has maintained a presence on the volcano ever since.

Lorrin A. Thurston   Thomas A. Jaggar, the observatory's founder, attempted a summit expedition to Mauna Loa to observe its 1914 eruption, but was rebuffed by the arduous trek required (see Ascents). When geologist Thomas Jaggar of the Massachusetts Institute of Technology gave a lecture in Honolulu in 1909, he was approached by businessman Lorrin A. Thurston (grandson of Asa Thurston who was on the 1823 missionary tour) about building a full-time scientific observatory at Kīlauea. The Hawaiian Volcano Research Association was formed by local businessmen for its support. George Lycurgus, who owned the Volcano House at the edge of the main caldera, proposed a site adjacent to his hotel and restaurant.

Mauna Loa [SEP] Monitoring
Established on Kīlauea in 1912, the Hawaiian Volcano Observatory (HVO), presently a branch of the United States Geological Survey, is the primary organization associated with the monitoring, observance, and study of Hawaiian volcanoes. Thomas A. Jaggar, the observatory's founder, attempted a summit expedition to Mauna Loa to observe its 1914 eruption, but was rebuffed by the arduous trek required (see Ascents). After soliciting help from Lorrin A. Thurston, in 1915 he was able to persuade the US Army to construct a "simple route to the summit" for public and scientific use, a project completed in December of that year; the Observatory has maintained a presence on the volcano ever since.
