In the early 20th century geologists had a limited understanding of volcanoes. Plate tectonic theory was still half a century away. Radio communications in remote, volcanically active areas were unreliable or non-existent. Eyewitness accounts of volcanic eruptions were difficult to gather. Seismographs, an essential tool for contemporary volcanologists, were almost unheard of in Alaska. For many years, little was known or understood about what happened in early June 1912 on the northern Alaska Peninsula.
