The Novarupta-Katmai eruption of 1912 - largest eruption of the twentieth century; centennial perspectives
Wes Hildreth, Judy Fierstein
2012, Professional Paper 1791
The explosive outburst at Novarupta (Alaska) in June 1912 was the 20th century's most voluminous volcanic eruption. Marking its centennial, we illustrate and document the complex eruptive sequence, which was long misattributed to nearby Mount Katmai, and how its deposits have provided key insights about volcanic and magmatic processes. It...
