Катмай
By 1898 there were reports of frequent earthquakes in the vicinity of Katmai Pass. These intensified around June 1, 1912, inducing the few local residents to leave. Katmai and Novarupta erupted on June 6 with a noise heard in Fairbanks, away, and Juneau, distant. Heavy eruptions continued through June 7, then gradually declined from June 8 onwards. Ash fell deep in Kodiak, and ash fell on the Alaskan mainland and eastwards as far as Puget Sound. Atmospheric haze was noted worldwide, and temperatures were depressed in the northern hemisphere during the second half of 1912. Initial reports pinpointed Mount Katmai as the center of eruption. Later reports cast doubt on Katmai's primary role, and it was not until 1954 that Novarupta was found to be the primary volcanic center. The region around the mountains, which had received heavy ashfall, was devastated.
