The Character of the eruption as indicated by its effects on nearby vegetation Scientific results of the Katmai Expeditions of the National Geographic Society
Griggs RF. 1919. The Character of the eruption as indicated by its effects on nearby vegetation Scientific results of the Katmai Expeditions of the National Geographic Society. Ohio Journal of Science. 19(3):173-209
This paper discusses the effects of the Katmai eruption on vegetation. Rains bearing sulphuric acid in such concentration as to destroy plants occurred as far as 300 miles from the volcano. An area of 7,300 sq mi was covered with ash so deep that it destroyed plants. Blasts from the volcano killed trees 25 miles away. "Mud flows" were so hot as to reduce to charcoal all vegetation in an area of about 53 sq mi. Fires destroyed an area of about 100 sq mi. The recovery of the vegetation is discussed and contrasts are made with Kodiak. Refers to the 1912 eruption of Katmai.
