"far field." In 1935, Jagger called on the United States Army to bomb lava flow that would soon reach the headwaters of the Wailuku River, which supplied water for the town of Hilo. His hope was that the lava tubes or channels could be destroyed, thereby robbing the advancing flow while feeding another flow that would re-cover the same area. The flow was bombed on December 27, and lava stopped flowing during the night or early morning of January 2, 1936. According to the United States Geological Survey, "Whether or not the bombing stopped the 1935 Mauna Loa lava flow remains a controversial topic today." Jaggar remained director of HVO until 1940. The Thomas A. Jaggar Museum in Hawaii Volcanoes National Park is named for him. In 2018, the museum closed when earthquakes associated with the eruption damaged its structure. , many of the museum's artifacts are in storage.
